Thank you to anyone who can help.
I searched for a resolution in this forum for my specific driver, but didn't find one, and following the advice of numerous others who had this problem has failed to help, so far.
I have a Dell Inspiron laptop 32-bit and upgraded Ubuntu to Pangolin 12.04, suddenly I have no wireless. I have a Broadcom STA driver, but when I try to activate it under "Additional Drivers" I get:
"Sorry, installation of this driver failed.
Please have a look at the log file for details: /var/log/jockey.log"
When I go to settings/wireless it says, "Firmware Missing"
Following instructions from Chili555 in a thread very similar to my situation, I opened a terminal window and entered:
lspci -nn | grep 0280
This is what I got:
0c:00.0 Network controller : Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
I don't see a solution for "4315" on this forum, yet. Here is the thread I'm talking about, that's similar to my situation:
I sincerely appreciate anyone who can help, please keep it simple as I'm not as much of a techie as you all, thank you!
