    wifi will not connect

    I've done some looking and none of the ideas have worked. I've tried turning on and off the wireless, and when I try:

    Sudo iwconfig wlan0 channel 03

    I get device or recourcse busy.

    So I've tried the command with networking off, same deal.

    I want to change channels because every other device in the house seems to connect to the network just fine, except my lubuntu machine. My ubuntu machine, windows 8 machine and android devices work just fine.

    Sensativity is forced auto on my card so I cannon set sens...

    Thanks guys!

    Re: wifi problem, channel change problem.

    Hi,, the channel selection/setting is done at the router.
    Not the wlan0 settings. Your other machines will auto/adjust
    to the channel change. Generally chan 1 or 11 seem to work best
    with Ubuntu, and also set to wpa2. Hope that helps.

    Well its not a channel change problem I've discovered as my ubuntu (12.04) machine works fine in the same place, same with my android device.

    This is exactly what happens:

    -I boot the machine up
    -it connects to the network for about a minute
    -it all of a sudden seems to not find the network, even though the machine right next to it shows full strength along with previously showing full strength on my "problem" system.

    Lshw -C network shows:

    Description:wireless interface

    Vendor: Ralink corp.

    Sorry if that doesn't make sense. I had to take type it from my phone as well I'm or able to connect with the machine right now lol

    Help would be fantastic

    new update!

    the wifi seems to stay connected until I use it. When I use firefox it automaticly disconnects, but if I dont use the internet, it stays connected, until in use.

    this happens about one boot per day. other than that, it auto disconnects.
