OK, for the ones of you that keep saying it has to be some sort of interference, let me run this problem by you. I have a Netgear WNR2000 which I got from a friend. He had 1 PC connected through this router by LAN, 1 laptop on WiFi, and 1 PS3 also on WiFi. He lives 15 miles from anyone, so no one around could be stealing his WiFi. This router however, has the same problem at his house and mine which has a lot more devices. The LAN works fine on the router, but when anything gets connected to its WiFi the speeds drop from 54mbps to 2mbps. After reading some articles online, I was able to increase WiFi speeds to 5.5mbps by, and get this, DOWNGRADING the firmware!!! This router makes no sense. No device in his house could be causing the problem, I know. As for my house, everything is protected by the highest encryption methods I could mustar. Unless someone can explain this, (cause NETGEAR can`t) I`m sticking with the thought that Netgear just flat out sucks, because my belkin has no problems at either house.
