Comment 10 for bug 989610

Same issue on TravelMate TM8372TG-5454G50Mnbb. Unfortunately Steffen's work-around didn't work for me.

I also tried following the instructions at https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#b43_-_No_Internet_access but when I returned to Additional Drivers b43 didn't show up.

What did work was manually building and installing the Broadcom hybrid wireless driver available from here: http://www.broadcom.com/support/802.11/linux_sta.php

The README.txt is very clearly written. One caveat though: Running `make` I received a compiler error about 'ndo_set_multicast_list' not being a recognised field or something. An internet search turned up that all you have to do is change 'ndo_set_multicast_list' to 'ndo_set_rx_mode' in the code (src/wl/sys/wl_linux.c, line 388). It's really very easy and it compiles fine after this, and you can continue following the README to install your newly compiled kernel module.

One (more) caveat: it may be my imagination but it appears as if my signal strength is now *slightly* less than it was under 11.10. Perhaps it's the same though and something has just changed in the way it's reported, like what happened with an iOS update a while ago and got a lot of people upset.

Anyway, if anyone else can't get Steffen's method to work I this proves useful.
