    Unhappy Wireless BCM4312 STA won't even turn on after downloading 10.10

    Ok so i am very new to ubuntu and i've tried various solutions that have been posted on this fantastic forum, but to no avail. I have a BCM4312 Broadcom wireless card. Since i transferred my OS from vista to ubuntu my external wireless switch doesn't seem to work (No light turns on when it's in the On position). I thought this was really weird so i did the whole activate STA drive and reboot while plugged in via ethernet to get all updates etc etc. That didn't work either, so I decided to try a ndiswrapper guide, i found an inf, but it gave me an invalid drive icon in the ndiswrapper window and i did get the right inf. SO then i thought id try some blacklisting and i blacklisted good old wl1 and then when i did the schw -C network check the config simply read latency: 8 (if i do recall)....I checked my BIOS too and it seems that everything is enabled as it should be. Anyone have any hints besides activate STA and reboot, cause its been done prob 8 times by now. Thanks.

    Ok i forgot to add some specs about my machine and situation.

    I'm running a Dell Vostro 1320 laptop.
