Ok so this problem started about 3 or 4 days ago, I can't remember doing anything to my system that might have caused it. My internet be fine for a bit then get really slow until I got into cmd and do ipconfig /release and /renew. This fixes it for like 1-5 minutes. I have no idea really, I've tried different NICs so it's not that, other computers on my network seem to be fine, I tried a different router even. The one outstanding thing I see is that when the other computer on the network is on it seems to do it more often. Sometimes when that computer is off it is even normal. I have no idea what to do.. this is really f-ing annoying, please help!
