I recently completed my first PC build and I had a cheap USB WiFi adapter laying around and I thought it would work well. But the little piece of junk can't handle my 80 meg down speed and craps out after 50MB of downloads. So I need a new adapter soon but I don't want to buy a junk one. I'm willing to spend $50 on one but I'd like to get a decent one and I know there are a ton of bad ones out there. Please help me pick out one.
