Slow Wireless: Change the Channel
If the wireless connection to your computer seems really slow, try changing the channel. Since your router's wifi shares the same spectrum with cordless phones (2.4 GHz), the signals may collide leaving you with a very slow connection to the internet. Point your browser to your router (https://192.168.1.1/wireless.htm works for some Linksys) and just change the channel settings. Eleven channels are available, so just keep changing until you find one that works.
