    No wifi signal found

    I just installed 10.10 on a Dell Inspiron 1300. The wired connection(eth0) works fine but I get no wireless signal when I unplug and try to connect to my network/internet. It shows that wlan0 does exist but it gets no signal. I've used the rfkill to make sure that it wasn't blocked and everything seems to be ok, except I get no wireless signal.

    I uninstalled Network Manager and installed Wcid and it found nothing. I even tried installing several signal scanners I found in the package manager. I've removed, updated and reinstalled the broadcom drivers. I still get nothing. The wireless signal from my router is nonexistent according to Ubuntu.

    The wireless works fine when I put my windows XP HD in and it also works fine when I put my Mepix or PCLinux OS HDs in the laptop. So I know that the wireless card is not busted.


    Someone please help, I'm stumped and have no idea what else to do.

    today no network connection. The eth0 and wlan0 are both not connecting.
    I run all the various rfkill commands and get nothing.

    Have a hunt (on this site, for a start) for mentions of broadcom and problems - I think I remember one a couple of days ago, with a suggestion to remove the linux drivers and use the Windows inf file (via ndis...?)

    this post goes further, and tells how to fix (one) failing broadcom chipset.

    I figured it out. I had to uninstall the driver and install a new one. once I did that I worked just fine.
    I searched the forums/site and did everything mentioned, but none of those drivers worked. I actually found the correct one by mistake.
