    Unhappy Cannot find Wireless network

    Hello everyone,

    I´m a new Ubuntu user and I´m still learning to work with Ubuntu. I installed Ubuntu 8 a couple of weeks ago and when I was finished Ubuntu was unable to find my wireless network (at home and at work). Eventhough every other PC can connect to the network.

    I figured out how to fix this problem, with some help from so guy at work. But now that I´ve updated to Ubuntu 9.04 the problem is back. The guy from my work isn´t able to help me (very busy guy).

    Therefor I would like some help from you guys. How can I make my Ubuntu version find my wireless networks? I would need a detailed overview of the steps I need to take.

    It´s an desktop Ubuntu 9.04 version on my Dell laptop inspiron 1521. I was able to post this thread because of my Windows version on the same PC.

    Please help me with this problem..
    Thanks,
    ConanB

    I'm not sure, but you may need to install some 3rd party drivers for your wireless card, in the menus:

    System > Administration > Hardware Drivers

    Check to see if there is an appropriate driver for your card?

    I´v just tried the above by trying a different driver, but this driver needed to download. Seeing this wasn´t possible I tried deactivating the current one and activating it again. After I did that Ubuntu was able to find the wireless networks and connect to them.

    But when I try to start Fire Fox and go online I get a network error (right away). The router works perfectly. Does anyone have any ideas?

    Current driver: Broadcom STA wireless driver.

    Thanks.

    The following output came up:

    The issues has been solved by deactivating and activating my driver. The issue that is still a problem is the switch at my work. I´ll let you know which switch this is asap i´m back at the office.

    Ok, try this:

    Go to: http://ubuntu.cafuego.net/dists/hardy-cafuego/broadcom/

    and get the b43-firmware .deb package. Now, install it on your computer (double click) and restart.

    That should take care of the wireless issues, hopefully
