I think there might be something wrong with my wireless card, but I'm not sure what.
When I start my computer, the internet works fine for about 15-20 minutes, then it just stops. When I click on "Available networks" to reconnect, NOTHING shows up, but I know that my network is available because it's working on other computers. I also notice a LARGE spike in memory usage when this happens. The only way to make the internet work again is to restart.
I have a Linksys WMP54GS PCI with SpeedBooster.
