Affects kernel 3.8.0-19-generic (stock on raring) too. I noticed wifi connections dropping constantly and overall pretty bad wifi performance after upgrading to raring recently. Testing with a 3.6.3 kernel produced the same results. At first I thought the firmware was to blame but after toying around with the open source b43 driver and b43-fwcutter (I'm using a MacbookPro 8,1 to test this) and comparing the installed firmware with the files from the proprietary Broadcom archive as described at https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#b43%20-%20Internet%20access I decided to use an older kernel.
And indeed the only way to eliminate this is to use a 3.2.0-32-generic image (the upgrade to raring removed quite a few images from /boot :-( ). I will try a 3.9 kernel as outlined above once I have the time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1142385 Title: B43 Wireless Autoconnect Failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1142385/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
