If you are having problems with your WiFi connection, such as dropouts or disconnections, slow speeds, etc., it could be interference on your router’s WiFi channel. (Yes, your router has channels, just like your TV.) One way to check this out is using WiFi Stumbler. This is a free (beta as of this writing) online tool that uses Java to search out all the WiFi networks and reports their signal strength.
Here is a screen capture of WiFi Stumbler.

Find your WiFi network on the list, then look at the Signal (%) column. If the percent is low, or there are other WiFi Networks using the same channel as your router, it might be time to make some adjustments. In order to the change WiFi channel on your router, please consult your router’s documentation or search the manufacturer’s website.
In my case, my router’s WiFi strength is pretty good and I don’t have any problems with it. However, I know someone who is having problems, so I’ll be using WiFi Stumbler to help troubleshoot their network.
