Wireless interference

   

Wireless networks are awesome... when they work. Sometimes other devices interfere with your wireless signal. Any device that emits a signal can interfere with your connection. Common offenders include cordless phones, wireless speakers, microwaves, and Blu-Ray players.

Testing for wireless interference

Connect to your network through ethernet. (You know - the yellow cable) If the problem goes away after connecting through ethernet, there's a good chance something is interfering with your wireless.
