    no internet

    so i tried to finally set up my wireless internet on my inspiron 1521 with ubuntu 8.10 yesterday i upgraded to the new 9.04 thinking there would be something new that would make it easier to connect but nothing.
    so i find this https://help.ubuntu.com/community/Wi...eisty_No-Fluff and do all the steps (2x)
    now i have no ehternet connection or wireless on my laptop!!

    when i look at 'connection properties' on the taskbar the only connection in the drop down menu is 'lo' and the status is idle with 44 packets sent and receieved at one point i remember it haveing eth0 and wlan0 before following the tutorial!

    iwconfig
    lo no wireless extensions.

    eth0 no wireless extensions.

    wmaster0 no wireless extensions.

    wlan0 IEEE 802.11bg ESSID:" "
    Mode:Managed Frequency:2.412GHz Access point: Not- Associated
    Tx-Power=20 dBm
    Retry min limit:7 RTS thrff Fragment thr=2352 B
    Power management: off
    Link quality:0 Signal Level:0 Noise level:0
    Rx invalid nwid:0 Rx invalid crypt:0 Rxinvalid frag:0
    Tx excessive retries:0 Invalid misc:0 Missed beacon:0

    pan0 no wireless extensions.

    any help would be great Thanks!

    You should see them under the gnome network manager in the panel. If you dont try activating the other driver.
