The b43 does not support 5GHz on this chip and 3.4GHz connections are so unreliable and slow that I lost quite some hair because of that one. Basically the connection drops either after some time (10-20 mins) or as soon as there is more than 5 Megabytes of traffic to handle.
The standard wl driver does recognize the card (only b/g), but does not connect at all. I'm now using this driver for around half a year (version 6.20.155.1 +bdcom-0ubuntu6 ) without a single connection drop and data rates of around 13 MB/s which is something I never experienced in Linux ever before. Here's some more people happily using this driver with the BCM4331: http://www.hackermusings.com/2013/02/better-wireless-drivers-for-the-bcm4331/ Please, please, keep it working for the 4331 even if it might not be explicitly listed as a supported device in its README. I've been using broken WiFi drivers in Linux since 2004 and just got it working properly half a year ago. Don't take that away from me again :D. Btw, Right now I'm using Saucy + linux-generic-3.8.0-030800 + 6.20.155.1 +bdcom-0ubuntu6 since the minute I reported this bug without any connection drop on 5GHz. ** Changed in: bcmwl (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1189611 Title: bcmwl-kernel-source 6.30.223.30+bdcom-0ubuntu1 fails to see 5GHz networks and is unstable on 2.5GHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1189611/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
