Improving wireless networking range

If you're having problems with the range or reliability of a wireless network (at home or at work), consider eliminating 2.4 GHz cordless phones in the area. Most wireless access points operate at 2.4 GHz as well, so a simple cordless phone could be interfering with the network signal.

An old 900 MHz phone is an option, but 5.8 GHz phones are readily available as well.

If you continue to have problems with the signal, the source of the problem may still be in your own residence (items such as microwave ovens, bluetooth-enabled devices, baby monitors, flourescent lights, wireless game controllers, etc. can also cause interference). Alternatively, a neighbor could have a 2.4 GHz cordless phone, or even a "competing" wireless access point. In that case, you may need to move your own access point, or at least change the channel that your access point is operating on (it's not too difficult to do; see the instruction manual).

Of course, interference works both ways. Crackling noises on your cordless phone may be caused by interference from any of the devices mentioned above. Also, don't forget that you may be the cause of somebody else's interference problems. If you live in, say, a dorm where wireless networking is relied upon by dozens of people, consider doing them a favor and upgrading your cordless phone to a 5.8 GHz model. That phone may someday cause interference with future wifi networks, but for now, it will be pretty safe.
