I literally just installed ubuntu and it seems to be working great except the network is deadly slow.

I'm running a TL-WN951N wireless card which can download at about 600-700 KB/s in windows but in Ubuntu the max speed it seems to get is around 5KB/s. I guess I should note that my WAP is only wireless-G but like I said, I can get much better speeds in Windows.

I'm testing the speeds by downloading files from here: http://mirror.internode.on.net/pub/test/

Anyone have any idea? I saw some people recommend downloading drivers and compiling them myself but I'm really really new to all of this so would appreciate someone babying me through it so I don't brick my computer!

Here are the results of lspci -v:
