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.
