    RaLink 3090 unstable wireless connection

    Recently I moved from Windows, and since I installed a Linux distro(I'm using Xubuntu 13.10) my wireless connection is uncommonly slow (~50kb/s from ~2mb/s). I got no problems using wired Internet from the same router. I've read about alot of possible issues around the web the past couple of days, i tried disabling ipv6 and n connection, wicd, edited nsswitch.conf, did wlan0 power off, got rt2800 firmware pack(i think that here is the problem, no fix found tho), checked blacklist, modified channel and dns and etc.
    What i got is, that every time i connect to my wireless network my internet is good for the first 1-2 minutes, then it drops. I think that this would explain the problem to a person, that is into network and wireless.
    Thanks!

    Would you be so kind to post the output of:
    Code:
    sudo lshw -C network
    lspci | grep Network
    and 
    sudo nm-tool
    Thanks,
    Chris
