I was able to get fairly good speeds and steady video/gaming. However, after I upgraded to Windows 7 64-bit, I am now unable to get more than 5% traffic, no matter how hard I push the system. I am on a wireless network (no hardlines available), using a D-Link WDA-2320 with manufacturer's drivers.
Video is extremely slow (cache pausing a stream takes almost 30min to get 5min from youtube) games are out of the question (autobounce for bad connection) and even firefox is slow. There is also an issue with port forwarding that I posted separately which may be related.
Nothing about the internet set up changed between before and after this problem started besides the change in OS. Does anyone have any idea what could be causing this and how to fix it?
