Michael Zanetti, regarding b43 not working as expected, you would want to file a new report following https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#b43_driver so that the firmware (or other root cause) gets fixed, and allows for your chip to work as expected.
Regarding bcmwl-kernel-source, the issue you are reporting is an upstream one. Could you please report this problem to Broadcom by following the instructions _verbatim_ at https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#Broadcom_STA_Wireless_driver ? Thank you for your understanding. ** Changed in: bcmwl (Ubuntu) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1387221 Title: 14e4:4331 [MacBookPro10,1] 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/1387221/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
