The problem seems to have fixed itself, so this question is now irrelevant.

I've been having an annoying wireless internet issue in 11.10, where my download speeds are EXTREMELY slow. I had no problem with my internet in 11.04, but in 11.10, my download speeds are abysmal. I always used to get As on the speedtest.net test, but now, I get Cs or Ds. I made a topic in the Ubuntu forum for assistance, but they've been of no use, so I came here. How can I fix whatever the problem is and make my download speed the way it was? Here is some information about my internet and such:

There is a difference between the wifi bandwith and the internet bandwith... From what you wrote it's not clear - for me at least - which one might be the problematic.

Can you try and transfer files between different computers on the wifi network? That way you can see if the wireless connection is working properly or not - if it is, the problem is in your internet connection.

That's the thing, I don't know what the problem is. But I can't do the file transfer procedure as the other computers on my network are Windows and I have no idea how to transfer files around to them. –  Icedrake Dec 24 '11 at 23:08
    
Ubuntu detects Windows shares great (granted, I didn't try it with Windows 7), so it might just simply work :) In Nautilus, try Browse Network to see if it is –  dinchamion Dec 25 '11 at 0:45

The problem fixed itself, I have no idea how, but it did.
