My laptop (Dell Inspiron 17R 5720) came with preinstalled Ubuntu 11.10. I removed it and installed 12.04. Now I can't find driver for wireless. Apparently, in 11.10 there was Broadcom-STA driver. But in 12.04 there is no additional drivers to install. I tried using:

sudo m-a a-i broadcom-sta

But building fails on 26%. How can I install driver?

According to lspci i got:

Broadcom Corporation Device 4365 (rev 01)

Actually, i found a patch and applied it to wl_linux.c, now broadcom-sta compiles with make command. I installed resulted module (wl.ko). It loads and just does nothing. Wi-fi still doesn't work. I wonder whether I did something wrong or this is wrong driver (strange though, in OEM 11.10 in list of 3rd party drivers there was Broadcom STA (although it was not activated)). – NilPointer Oct 21 '12 at 4:15

Looks like I've reached end of that long maze on my own. I've installed modified deb from here:


And loaded kernel module "wl". After that, Wi-Fi started to work. I added wl to autoload at boot time... Anyway, looks like problem is solved.
