Im facing a peculiar problem with Ubuntu 12.04. When I'm on wireless all my webpages load very very slowly but videos + transmission downloads are very fast(actual speed).

I tried all fixes - upgrade kernel,ipv6 disabling,wifi-n diabling etc.. This happened suddenly without me making any changes to network settings. Eralier it was working flawlessly.

Also when I run a windows VM on top of this ubuntu 12.04 there the webpages run very fast(Like normal)..

So stuck on how to fix this issue..

My o/p of lshw :-

$ lshw -C network

Does it make any difference if you turn Transmission of? –  mikewhatever Jan 8 '13 at 5:50
