More info - I have been using my laptop to reply to this and just now I switched back over to my desktop and now the speed is back to 3.75 Mbps (where an hour ago, I couldn't get .75).
GeeRant, I have been having the EXACT same problems as you on a brand new Windows 8 computer (Lenovo Yoga 13). I got it 3 weeks ago originally but called Lenovo for a replacement since I thought it was the wireless card or something and they have a very short return period, so I did not want to waste time figuring it out. However, the new one is having similar issues. Here are the problems with the computer (all speeds are from speedtest.net but they are confirmed by downloading pages like Facebook or NYTimes and making sure a slow speedtest corresponds to slow downloads in typical usage):
1. Sometimes finds the network with 2-3 bars and connects.
2. Is sometimes fast (2-3 Mbps) but sometimes crashes down to 0.1-0.3 Mbps while my old computer right next to it is still getting 4-5 Mbps.
3. Sometimes finds the network and connects but says "No Internet Connection" or drops the connection and stops showing any networks for a few minutes even though my other computer is connected to the same network and it's fine.
Does anyone have any insights?
