Choose Your WiFi Channel Wisely
If you are running a WiFi network in your home, pay attention to the channel number on your wireless frequency. Most (if not all) routers are set to channel number 6 by default. There are 11 possible channels to choose from. If you are broadcasting WiFi in an area that has a lot of networks, you could be having problems with interference if several networks are broadcasting on the same channel.
If you have an iPhone or iPod Touch, I have an easy way to find which channels your neighbors are using. Grab the app WiFiFoFum and see all channels which are in use in your WiFi area. I love this app. It is extremely helpful in many ways beyond this single example. I highly recommend it. I’m sure desktop solutions are available, but I prefer using my iPhone for portability.
Once you can see a map of channels in use nearby, choose a channel for your network that is not in use by other nearby networks. Technically, each channel number represents a range of frequencies, many of which still overlap each other. To get as far away from other networks in the channel spectrum, choose a channel number that is 5 points away from other networks. For example, if everyone around you uses channel 6, choosing channel 1 or 11 would be best in that case. You won’t always be able to space your network that far from the others, but choosing any number not being used by others would still be helpful. I am providing a link that you can read for more information about this topic.
In addition to wisely choosing your WiFi channel, also make sure you also have renamed your network from the default (such as “linksys”) and have turned on WPA or higher security. For additional security, it is also wise to change the router login/password and disable wireless access to the router setup page.
