I have an enormous problem: I've a Sony Vaio VGN-NR21S with win7 and Ubuntu 12.04 in dual boot. With Windows everything is fine (except that is windows) but with Ubuntu the wireless connection is awfully slow, basically unusable.

I've already search for similar discussion but the solution proposed didn't worked. I've noticed this issue also in live mode both with ubuntu and linux mint. I've installed Ubuntu onto an Acer that shows the same problem when connected via wifi to my router, so I think that maybe the issue is about compatibility with my home router.

I really need help, I don't want unistall ubuntu! Please tell me which output u need to help me, thanks.
