Airport card painfully slow or doesn't work at all

[rgwoehr]

A day or two ago I booted up my hackintosh and my Airport connection was slow. When I ran a speed test it was around 2MBps while my MacBook Pro was around 19MBps. Today when I booted it up it says it's connected but nothing loads, and if I try to load a web page it will drop the connection and nothing shows in the WiFi menu in the menu bar. I checked the network preference pane and all the settings seem to be fine. I tried repairing permissions, reinstalling kexts, swapping Airport cards with my other hackintosh and still nothing. Anyone have any ideas?

The same Airport card works fine under Windows.

Edit: forgot to mention I'm running 10.7.4

Problem solved; apparently OS X decided it didn't like WiFi channel 1 anymore. I changed the router to channel 6 and it's working again.
