Laptops with wireless routers that keep failing may indicate that the device is suffering from interference. To solve this problem, it is recommended that the owner download and run NetStumbler, which could locate another access point with a strong enough signal or multiple access points on the same channel. Interference could also be caused by nearby wireless devices such as cordless phones that use 2.4-Ghz frequency range. One solution to this is to contact a ham radio operator with equipment that can convert the signal to a lower frequency.
