running ubuntu 12.10 usb wireless card is N300. Internet works fine when just surffing the web but once i start to download anything ie bitorrents and even updates the N300 stops working. I still have a connection on the top right hand side but no internet activity at all. First i thought maybe the card was junk so i went out to got a N600 still the samething. Then i tried with a windows laptop the connection was great even downloaded a movie 1gb in 12 minutes with no problem. Any ideas????
