I have exact the same notebook model with the same wifi card. I'm using the mainline kernel build and the card is still not working.
To confirm the use of mainline kernel, uname -a returns Linux darlan-G75VX 3.9.0-030900-generic #201304291257 SMP Mon Apr 29 16:58:15 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1173761 Title: Broadcom Corporation Device 43b1 (rev 03) - not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1173761/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
