Suggestion 8: Use a less-crowded wireless channel
Note: This Option requires you to login to your router and is for more advanced users.
If you have neighbors, their routers and access points may be interfering with yours and causing the signal to degrade. Wireless routers can operate on a number of different channels, and you want yours on a channel with as little interference as possible. Though your router can probably pick the best channel for you, you want to make sure that it’s evaluating the situation correctly. Use a tool like Network Analyzer Lite or WiFi Analyzerto see where your wifi network falls in relation to everybody else’s, and switch channels manually if your router picked poorly.
You should avoid use 40MHz-wide wifi networks on 2.4GHz if there are other wireless networks nearby. Your router shouldn’t do this if it obeys wireless coexistence mechanisms, but it might not. (And if you’re setting up a wifi network in a wifi-free location, feel free to force your router to run 40MHz channels if it isn’t already—and you have the option to do so.)
