We didn't get a 3G iPhone at Macworld, but at least we got a software update that brings pseudo-GPS abilities, customizable home pages and more to Apple's coveted handheld. Here’s a few quick first impressions.
GPS: Actually, we're not talking actual GPS here; instead, this update to the iPhone's Maps app triangulates your position according to your distance from the nearest cell phone towers. You activate the feature by tapping a little bulls-eye in the left-hand corner of the Maps interface; 10 to 30 seconds later, a blue circle appears on the map showing your approximate location—and "approximate" is the key word. In my first few tries, the circle encompassed almost a third of Manhattan—a pretty massive swath of land, and not terribly helpful for, say, finding the nearest ATM. A couple of tries later, however, Maps found my location within a block; not bad at all.
Customizing the home page: Used to be you had to hack your iPhone to tweak the icons on the home page. Now you just touch and hold an icon, and all the icons begin to wiggle; next, just drag the icon wherever you want it to go, even on a subsequent home page (you get a total of nine). Also nice: you can turn Web pages in the mobile Safari into icons on the home page. (Apple calls them Webclips, but they don't work like the real-time, updating Webclips widgets in Mac OS X Leopard.) The wiggling, moveable icons will come in especially handy once third-party iPhone apps become widely available.
Chapters, subtitles, and languages: I was only able to test chapter support for videos (I don't have any iTunes movies with subtitles or alternate languages yet), and it worked nicely; you just tap an icon to the right of the playback controls, and the video image flips around, revealing chapter titles, thumbnails and time elapsed.
Lyrics: Not as impressive as the other new features, if you ask me. Basically, if you have a song in your iPhone tagged with song lyrics (select a song in iTunes, click Command-I, and click the Lyrics tab to add lyrics) field, you just tap the cover art while the song is playing to see the words. Unfortunately, the lyrics display on the iPhone seems to do away with line breaks, which makes a mess of nicely formatted choruses and the link. Pretty disappointing.
SMS messages for multiple recipients: One of the most puzzling omissions on the iPhone has finally been fixed; at last, you can send text messages to multiple recipients at once. Of course, the only drawback is that if you get into a back-and-forth with one recipient, everyone in the group will get your replies, which could get a little confusing. Still, a welcome improvement.
Note: Like each of the previous software updates for the iPhone, this latest patch will wreak havoc with hacked handsets; expect any unauthorized applications (including iPhone unlocking apps) to be wiped clean by the update.

New iPod Upscale Video to HD
A couple of upcoming iPod docks come with the standard "video out" feature, but with a twist—they'll upscale your images to 720p or 1080i. Pretty nice, but don't expect a full-on HD image, and brace yourself for the respective price tags.
Straight out of Macworld comes the DLO HomeDock HD, a sleek iPod dock with an HDMI output (along with composite and S-Video connections), an RF remote, and the ability to upscale standard-def iPod video to 720p or 1080i. Now, let's make something clear from the get-go: like upscaling DVD players, an upscaling iPod dock won't magically turn your iPod video into crystal-clear HD. Instead, upscaling devices interpolate 480p signals to take better advantage of 720p- and 1080i-capable displays. The results vary, of course; in the case of the DLO HomeDock HD, CrunchGear blogger Matt Hickey was impressed enough with the demo to call the HomeDock one of the cooler offerings at Macworld.
Another new contender: the Creative Xdock HD, which not only handles HD upscaling duties but also juices the audio as well, using a technology Creative calls "X-Fi Crystalizer" and CMSS-3D (enough initials for you?) to turn stereo sound from the iPod into full DTS surround sound (akin to receivers that convert stereo tracks to Dolby Digital Pro Logic II surround). Even better, the Xdock HD (which debuted last week at CES) can wirelessly transmit audio to the bundled X-Fi receiver.
Good stuff, but neither of these high-end docks come cheap: the DLO HomeDock HD will retail for $249 when it hits stores this spring, while the Xdock HD (also due this spring) will sell $399.

40 hour laptop batteries
Imagine running your laptop nonstop from New York to Tokyo -- crunch some numbers, work on a memo pop in a few DVDs -- and then do a full day of meetings, using your machine throughout the day and into the night. Imagine doing all this without ever plugging in your computer to recharge its battery.
This scenario may become reality in the near future, if Stanford University scientists succeed in commercializing a breakthrough in the laboratory. Assistant Professor Yi Cui and associates at Stanford's Department of Materials Science and Engineering said they have developed a method to increase the life of rechargeable lithium ion batteries to a whopping 40 hours.
Publishing in the journal Nature Nanotechnology, the Stanford researchers have shown that by using silicon nanowires as the battery anode instead of today's graphite, the amount of lithium the anode can hold is extended tenfold.
Revolution in Battery Design
"It's not a small improvement," Cui said. "It's a revolutionary development." And Cui means to move the development out of the lab as soon as possible. "We are working on scaling up and evaluating the cost of our technology," Cui said. "There are no roadblocks for either of these."
Cui has filed a patent on the technology and is evaluating the formation of a company or licensing the technology to a battery manufacturer. Potentially two-day batteries could be on the market within "several years," he said.
Silicon anodes are not a new idea. Researchers have known for some 30 years that they have the "highest theoretical charge capacity," but, until now, they haven't been practical because they change volume by 400 percent as lithium is inserted and extracted, the journal said. Cui's solution: a sponge-like network of tiny silicon nanowires, each of which expands but doesn't fracture.
"Nanowires grown directly on the current collector do not pulverize or break into smaller particles after cycling," the journal reports. "Rather, facile strain relaxation in the nanowires allows them to increase in diameter and length without breaking."
The Many Advantages of Nanowires
Not only can the nanowires handle the extreme volume changes, they also "provide good electronic contact and conduction, and display short lithium insertion distances," Cui wrote. "We achieved the theoretical charge capacity for silicon anodes and maintained a discharge capacity close to 75 percent of this maximum, with little fading during cycling."
The nanowires are grown directly on the metallic substrate that collects current, a process that has several advantages, Cui explained. First, the nanowires' small diameter can better accommodate the four-fold expansion in volume without fracturing. In addition, each nanowire is electrically connected to the metallic current collector, so all the nanowires contribute to battery capacity.
The nanowires also offer efficient "charge transport" and eliminate the need for additives to conduct electricity, which add weight, the journal stated. In addition to Cui, the researchers were Candace K. Chan, Hailin Peng, Gao Liu, Kevin McIlwrath, Xiao Feng Zhang and Robert A. Huggins.

New MySpace security issue McAfee has notified both MySpace and Microsoft
Security Watch is reporting a new MySpace security issue. The hack sendS an authentic looking patch from Microsoft to a person's computer, once they have clicked on a link to view a person's profile.
Once install the virus by hitting run, it opens a back door on the compromised machine and proceeds to download more down loaders, Trojans and a remote control tool from multiple servers. The infected files are coming from servers located in Malaysia and the Ukraine. McAfee has notified both MySpace and Microsoft but, at the time of writing, the booby-trapped MySpace profile was still live and serving up the malicious file.
When the article was published 01/13/08, MySpace had not fixed the issue, odds are very likely that they will be doing so in the future if not today as news gets out. The problem with getting this information out,is not everyone who uses MySpace reads security blogs or security news sites. Odds are most likely that there are going to be a huge number of people running around with compromised and virus infected computers.

What is a hardware firewall? Wi-Fi Facts Tips And Problem Solvers
If my router has one, do I need to run the Windows firewall or other third-party firewall software?
Wireless routers have a hardware firewall that safeguards the network by providing both incoming and outgoing protection. A hardware firewall will include network address translation (NAT) capabilities that make your PC invisible to anyone trying to attack it. If you enable the hardware firewall, you probably don't need a third-party software firewall. You should still run the Windows firewall, however, because it keeps a low profile and will stop basic worms if your PC gets hit by a drive-by downloader.

Should I worry about people grabbing my information when I browse the Web at public hot spots?
Yes, you should at least consider this possibility. Anyone can install packet-sniffing software that will enable him or her to eavesdrop on what you do at a public hot spot. These snoops can read your e-mails and see what Web sites you visit, but they will not have access to the files on your laptop, unless you have file sharing enabled. And they cannot see any messages or Web pages sent over the secure server connections typically used by banks and e-commerce sites.
If you use a VPN to access your corporate network, you can use it at hot spots to encrypt all transmissions and shield them from packet sniffers. If you don't have a corporate VPN but frequently use public hot spots, you might consider a consumer VPN service such as the PersonalVPN from Witopia ($39.99 per year, www.witopia.net) or BlowFish from HotSpotVPN ($10.88 to $13.88 per month, www.hotspotvpn.com). These employ powerful 128-bit encryption to protect your data as it is transmitted.

Should I allow other people to access my Wi-Fi service? Wi-Fi Security Tips And Facts
Some users often see no harm in sharing there Wi-Fi signals, giving neighbors and even total strangers free access to the Internet. Others hold fast that piggybacking can open their networks to potential danger. The decision is yours, but if you choose not to encrypt, make sure to disable file sharing. Assuming you have your hardware firewall turned on, the worst that probably will happen is that your throughput will drop if your piggybacking friends crank up BitTorrent every evening. If you want to determine whether others are using your unsecured network, most routers have a page that lists all the wireless clients currently connected.
Some people, are not comfortable with the idea of allowing just anyone to use their wireless service. Feeling that that kinda practice can make your network vulnerable to hackers, since anyone who uses your wireless signal is on your home network. Malevolent users, for instance, could release nasty viruses or hijack your PC. That's not vary likely, but you should avoid the possibility by using WPA to protect yourself and keep others off your network.

How do I share files on a wireless network? Wi-Fi Problem Fixs
You will need to set up a workgroup and make sure that all PCs are assigned to the same workgroup, then enable file sharing in Windows. First, right-click on the folder you want to share, choose Sharing and Security from the right-click menu, then click the Sharing tab. Put checks in the boxes labeled "Share this folder on a network" and "Allow network users to change my files" to enable others to modify the documents. Now just, click OK.
Which wireless channel should I use? Wi-Fi Tips and Tricks
Wireless 802.11b and 802.11g routers have 11 channels in the United States and 13 in Europe, and most routers come set to channel 6 as the default. If you experience interference—from a neighbor's router, for instance—you can change your channel to solve the problem. Channels 1, 6, and 11 are non-overlapping channels. So if your neighbor's network uses channel 6, change your router to 1 or 11. You'll typically find channel settings on the router's basic wireless-settings page. Just click the drop-down menu and select an alternate channel, then save the settings.
How do I automatically connect to a Wi-Fi network without having to manually connect the first time? Wi-Fi Tricks And Tips
If you just want to connect fast to any available Wi-Fi network, you can set your notebook to do it automatically. Go to Control Panel > Network Connections and right-click your current wireless network. Then click Properties > Wireless Networks > Advanced. Make sure the button next to "Any available network" is on, then check the box "Automatically connect to non-preferred networks."
How do I extend the range of my wireless signal? Wi Fi Problem Solvers
Improving a wireless signal is part trial and error. No two homes are alike, and no two solutions will work for everyone, but here are some common guidelines. First, position your antenna on a high perch clear of obstructions. (The wireless signal radiates down.) Keep in mind that certain things will interfere with the signal: metal, and dense building materials such as brick, stucco, and concrete. So avoid metal pipes and construction.
If changing your Wi-Fi antenna positioning doesn't help, you can get an extender (or "repeater"), such as the Linksys Wireless-G Range Expander WRE54G, available for around $90. Devices like this will boost your range from 50 to 75 feet, A somewhat easier approach is Wireless Garden's Super Cantenna. This $39.95 tripod-mounted, high-gain antenna connects to your router and can be pointed at a specific area to amplify the signal.

How do I open ports on my router? Wi-Fi Problem Solvers
Certain applications,IP Webcams, home FTP servers, and online games—require that you open ports on your router to allow outside requests to be sent to an internal computer on a home network. This procedure, called port forwarding, is pretty straightforward. First, you'll need to find out which ports you need to open for your particular application or service. Then, you'll open those ports on the router. All models are different, but the process is similar. Open your router's configuration tool, and find a tab labeled Port Forwarding. Enter the service or software name, then type the Start Port and End Port numbers. If you're opening one port, enter the same number in both fields. Select TCP as the protocol, then click OK. Check your router's Web site for instructions for your specific brand.
What should I do to secure my Wi-Fi network?
Routers offer two common forms of security: WEP, and Wi-Fi Protected Access (WPA) encryption. Both are easy to enable, although you'll get maximum protection from WPA. To activate security, go to your router's browser-based administration tool (the default address for most routers is http://192.168.0.1 or http://192.168.1.1) and look for the wireless-security area. WPA requires you to enter a simple security phrase (eight to 63 characters), or, with some routers, a more secure (but much harder to remember) 64-digit key. Similarly, WEP demands that you choose from 64-bit or 128-bit encryption, and enter an alphanumeric hex phrase,.
In addition to enabling wireless security, you can also disable the broadcasting of the Service Set Identifier (SSID, or network name). Doing so can make the network more difficult for hackers to see. Also, make sure to enable the router's hardware firewall (more on that later), and change the router's default password. And never enable file sharing, unless you really use it.

And never enable file sharing, unless you really use it.
I cannot connect to my router. How do I Fix This Wi Fi Problem
This is a problem with an almost limitless range of causes and solutions. First, make sure your router is configured for Dynamic Host Configuration Protocol (DHCP). If it is, try disabling and re-enabling the DHCP function. If that doesn't work, disable wireless security and see if you get a connection; sometimes a mismatched Wired Equivalent Privacy (WEP) key can drop the IP address. You should also check for electrical interference from competing devices such as cordless phones, baby monitors, alarm systems, and microwave ovens. Disable all suspect devices, then recheck your Wi-Fi connection. If none of the Wi Fi Fixes I mentioned work, reboot the router and all computers on your network.
How To Get Secure Internet access in a public hotspot
Wireless transmissions on a public hot spot are typically unencrypted, and thus exposed to snooping. All computers on a public hot spot are typically exposed to each other, and thus vulnerable to network attacks.
Use a software firewall
A good software "firewall" will protect your computer from network attacks.
Make sure you are using strong passwords on all system accounts (including Administrator) and on all user accounts.
When Using Microsoft Windows
Use Simple File Sharing (Windows XP only); or
Make sure that all network shares are secured with strong passwords (all versions of Windows). Use Control Panel, Administrative Tools, Computer Management, Shared Folders, Shares to review and check Properties of all network shares

Improving Wi-Fi Why high transmit power will tend to increase your interference with other Wi-Fi users, making you a bad neighbor
Higher Power WI-FI
Will having higher power Wi-Fi help improve your range, no, since higher power only helps on transmit, not receive. Thus it's only likely to help if the other end of your connection is using higher power as well, which is often not the case. Also, unnecessarily high transmit power will tend to increase your interference with other Wi-Fi users, making you a bad neighbor. It's usually much better to just improve your antenna, which helps both transmit and receive.

What hardware is needed to build a wireless network?
Wireless network adapters (also known as wireless NICs or wireless network cards) are required for each device on a wireless network. Some newer laptop computers incorporate wireless adapters as a built-in feature of the system. Separate add-on adapters must be purchased for most computers, however.
Popular wireless network adapters for PCs exist in the form of a PCMCIA "credit card".
Macintosh computers use the distinctive AirPort card. USB wireless adapters that do not resemble cards also exist.
No wireless hardware other than adapters is required to build a small wireless LAN (WLAN). However, to increase the performance of a WLAN, accommodate more computers, and increase the network's range, wireless access points and/or wireless routers can be deployed.
Wireless routers function comparably to traditional routers for wired networks. One generally deploys wireless routers when building an all-wireless network from the ground up.
An alternative to routers, access points allow wireless networks to join an existing wired network. One typically deploys access points when growing a network that already has a wired switch or router installed. In home networking, a single access point (or router) possesses sufficient range to span most homes. Businesses in office buildings often must deploy multiple access points and/or routers.
Access points and routers often utilize a wireless antenna that significantly increase the communication range of the wireless radio signal. These antennas are optional and removable on most equipment. It's also possible to mount antennas on wireless clients to increase the range of wireless adapters. This is common practice for wardrivers, but add-on antennas are generally not required in typical home or business networks.

One typically deploys access points when growing a network that already has a wired switch or router installed. In home networking, a single access point (or router) possesses sufficient range to span most homes. Businesses in office buildings often must deploy multiple access points and/or routers.
Access points and routers often utilize a wireless antenna that significantly increase the communication range of the wireless radio signal. These antennas are optional and removable on most equipment. It's also possible to mount antennas on wireless clients to increase the range of wireless adapters. This is common practice for wardrivers, but add-on antennas are generally not required in typical home or business networks.

What is wireless networking? Wi Fi How does it work?
A wireless network uses radio signals or microwaves to broadcast data and information. Rather than being transmitted through traditional coaxial, CAT5 ethernet or other standard wired methods, the data is beamed out over the airwaves.
Wireless networks offer advantages for some. Users with personal digital assistant (PDA) handhelds such as Palm Pilots, wifi enabled cell phones, or users with laptops can use wireless technology to allow them the convenience to move about while maintaining their network connectivity. Another pro is the ability for users to network desktop computers at various locations without having to deal with the hassle or expense of running a wired connection to that spot.
Most wired networks operate at 100mbps, and many organizations have upgraded to the newer standard of 1gbps.
A large percentage of wireless networks operate at 11mbps, roughly equivalent to the old wired speed of 10mbps. Most wireless network equipment available today is compatible with both 802.11b and the faster 802.11g which operates at speeds up to 54mbps. There is also a new, emerging wireless network standard, 802.11n, which theoretically increases both the speed and the range of the wireless network.
WHAT CAN AFFECT MY WI FI CONNECTION
Wireless network speeds are affected by obstructions such as walls and floors. Most wireless network equipment, for consumers in particular, also operates in the 2.4Ghz frequency range. This is the same range as other household devices such as cordless phones, baby monitors, etc. The interference from these devices, as well as microwave ovens and other electrical interference can greatly impact the range, speed and quality of your wireless network.

Accidentally connecting to neighbor's Wi-Fi Or Are They Connecting To Your Wi Fi
Products with the same (default) SSID seem like a single network!
Set a unique SSID in your wireless router or access point.
Set up security (WEP, or better yet WPA), a very good idea in any event
Some wireless access points support broadcasting multiple SSIDs, allowing the creation of Virtual Access Points - partitioning a single physical access point into several logical access points, each of which can have a different set of security and network settings.
Security Basics For Home ComputingThree Easy Steps
As a home computer user accessing the Internet, whether through a broadband connection or traditional dial-up, you should do the following three things at a minimum to protect your compute:
1.Install and maintain anti-virus software. There are plenty of great anti-virus software packages available. This software checks for known viruses by scanning your computer periodically. Most will also check for viruses on incoming email. It is important to update the software as well though. New viruses are discovered almost daily. At least once a week you should check the web site of the vendor that makes your anti-virus software to see if there is an update available.
2.Do not open unknown or suspicious email. Many viruses and worms use what is called “social engineering”. That is, they attempt to trick you into becoming a participant in the process. The latest viruses can “spoof” the sending email address so that it looks like it is coming from someone other than the computer that infected it.
If an email is not from someone you know, it is usually best to simply delete it without looking at it. If the email appears to be from someone you know, you should read the message carefully before opening any attached files. Viruses and worms often have bad English and poor grammar. Consider whether the person you know would really have written that message or forwarded you the attached file.
3.Keep your computer patched against known vulnerabilities. Almost as often as new viruses are discovered, new vulnerabilities are discovered as well. Many times they are in the operating system (like Windows), but vulnerabilities are also found in tools like your web browser, email software and other 3rd party tools. Left unpatched, these vulnerabilities can be exploited by hackers to obtain access and control of your computer.
Staying up to date can be difficult. Some vendors, such as Microsoft, have automated utilities that check for updates and notify you. Other vendors may have an email mailing list you can join so they can notify you of any new updates. If your vendor doesn’t offer one of these solutions, you may just need to periodically visit their support web site to check for any new patches or updates.

I Can't connect to wireless router or access point How Do I fix This
Most such wireless host devices have a web page that can be accessed with a standard web browser (e.g., Internet Explorer). Check the user manual for the address of the web page, and try to connect with a web browser.
If that doesn't work, try to ping the wireless host; under Microsoft Windows, click Start → Run,
type "%COMSPEC% /k ping WIRELESSHOSTADDRESS" and press [Enter].
If that doesn't work, check network addresses with Start → Run,
type "%COMSPEC% /k ipconfig /all" and press [Enter].
The wireless adapter network address will normally begin with the same three number groups as the wireless host web page; e.g., if the wireless host web page is 192.168.1.254, then the wireless adapter should be something like 192.168.1.11.
If you have a wireless router (not an access point), the Default Gateway should normally be the same network address as the wireless host web page.
If all else fails, you may need to reset the wireless host to factory default settings, and start over. Check the user manual for how to do this.

Wireless router locks up and has to be restarted How Do I Fix This
Possible causes:
Firmware bug Upgrade firmware to the latest version, downloaded from the manufacturer website. In some cases it may be necessary to ask Support for more current "beta" firmware.
Upgrade to a better/newer router
ARP cache/table overflow (typically in an older router)
Overwhelmed by peer-to-peer (P2P) filesharing application (e.g., BitTorrent/Azureus, eDonkey/eMule)
Reduce the maximum number of connections in the P2P application. Start pretty low and then work up to a maximum safe level.

My Wake On LAN (WOL) won't work from the Internet how Can I Fix This
The problem is that for a router to send magic WOL packets to your network, you need either: 1.an external router interface for generating and sending magic WOL packets, or 2.manual enabling of a static route or directed broadcast. Many (most?) low-end routers don't have that capability because of the risk of smurf denial of service attacks.
WHAT IS A SMURF ATTACK?
The smurf attack is a way of generating a lot of computer network traffic to a victim site. That is, it is a type of denial-of-service attack. Specifically, it floods a target system via spoofed broadcast ping messages.
In such an attack, a perpetrator sends a large amount of ICMP echo (ping) traffic to IP broadcast addresses, all of it having a spoofed source address of the intended victim. If the routing device delivering traffic to those broadcast addresses delivers the IP broadcast to all hosts (for example via a layer 2 broadcast), most hosts on that IP network will take the ICMP echo request and reply to it with an echo reply, multiplying the traffic by the number of hosts responding. On a multi-access broadcast network, hundreds of machines might reply to each packet.
Today, thanks largely to the ease with which administrators can make a network immune to this abuse, very few networks remain vulnerable to smurf attacks.
The fix is twofold:
Configure individual hosts and routers not to respond to ping requests to broadcast addresses, and Configure routers not to forward packets directed to broadcast addresses.
Another proposed solution, to fix this as well as other problems, is network ingress filtering which rejects the attacking packets on the basis of the forged source address.

Wi-Fi Speed Whay Is my Wi Fi Connection Slow Slow
The raw speed reported by your wireless network adapter is not necessarily a reliable indicator of actual raw speed. The reason is that transmit speed fluctuates according to the wireless error rate, and when the wireless link is idle, unrealistic speed may be reported (since no errors are occuring when the wireless link is idle).
Data can only flow on one wireless link in one direction at any one time, which means that the maximum data transfer rate will be well below half of the raw wireless network speed.
Increase transmit power
Won't help on receiving, so higher power may well be needed at both ends.
Takes a lot more power to make a substantial difference in range.
May increase interference to other users of the frequency band.
Improving antenna (helping sending & receiving) is usually more effective & neighborly.

My Wireless connection drops periodically How Do I Fix This
Possible interference
Try manufacturer's wireless connection manager -- If your hardware came with its own wireless connection manager, trying installing and configuring it to manage wireless connections. (Some drivers will not maintain the association with the strongest signal access point in situations with high density access points.)
Too much wireless (RF) interference
Switch to a different channel
First try minimally interfering channels: 1, 6, and 11
If that doesn't solve the problem, try other channels
Remove interference (e.g., replace 2.4 GHz cordless phone with 900 MHz or 5 GHz cordless phone) Use a directional antenna or reflector pointed
toward desired radio, and
away from source of interference,
Switch to 802.11a (5 GHz)

Can't connect to Wi-Fi client bridge and Internet at the same time How Can I Fix This
In network terms, a bridge is transparent, passing data from each side to the other side (wireless to wired, wired to wireless). Thus in normal operation it doesn't have any use for IP addresses, just MAC addresses.
However, because of the need to manage Wi-Fi operation (SSID selection, WEP/WPA security, etc.), a Wi-Fi client bridge will typically have configuration screen(s) at a specified private IP address (e.g., 192.168.0.254) that can be accessed with a standard Web browser (e.g., Microsoft Internet Explorer) from a local computer. Unfortunately, unlike with a Wi-Fi router, a computer connected to a Wi-Fi client bridge can't normally communicate with both the client bridge configuration and the Internet at the same time.
How To Configure a Wi-Fi client bridge.
Problem: The NIC on a local computer needs a manually-assigned IP on the same subnet to connect to the client bridge config interface but then can't access the Internet, and when configured for DHCP through the client bridge can then talk to the Internet but not the client bridge.
Solutions:
Multihoming of the NIC (single link, multiple IP addresses)
For Microsoft Windows XP, see "Configuring Multiple IP Addresses on a Network Adapter" in Configuring IP Addressing and Name Resolution. Note: This only works with all manual addresses, not DHCP, which can be problematic when roaming unless managed with configuration manager software.
Two NICs in one computer, both connected to the client bridge:
one manually configured to talk to the client bridge config
the other with DHCP for the Internet.

client bridge config (manually configured)
Internet access (DHCP).

PROBLEMS WHEN I ADDED WIRELESS ACESS TO A WIRED NETWORK
When adding wireless access to a wired network, as in the diagram, be careful not to create double NAT problems. Since the wired router already has NAT, use either:
1.a wireless access point with no NAT instead of a wireless router (with NAT), or
2.a wireless router setup as a wireless access point.
