    Question Wireless Suddenly Stopped

    Hi Everyone,

    My internet was working an hour ago but seems to have stopped after installing some updates. I'm using Ubuntu 9.10. I've restarted my router but I know it's working because Windows works. My wlan card is a bcm4318 based card.

    It's able to see my network and lets me enter the WPA key but then it fails. I've trid changing security levels on router and machine to WEP to see if that was a problem but it wasn't.

    As I said it was working perfectly about an hour ago...

    ifconfig output:

    I did a re-install and it didn't work. Then I moved the antenna on my card a bit and it worked. I'm guessing my antenna might be a bit "dodgy".

    Thanks for looking.
