** Description changed:
Hardware: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)
This chip is working perfectly fine on 2.5GHz and 5GHz using version
6.20.155.1+bdcom-0ubuntu6 of the driver.
After upgrading to saucy or any newer version and installing version
>=6.30.223.30+bdcom-0ubuntu1 it fails to find any 5GHz networks and
connections on 2.5GHz are unstable.
Downgrading the machine to kernel 3.8.x and bcmwl-kernel-source
6.20.155.1+bdcom-0ubuntu6 (both from raring) makes the chip work again.
- UPDATE: Up to kernel 3.13.0-23 a patched working package of
bcmwl-kernel-source 6.20.155.1+bdcom-0ubuntu6 can be found in the comments of
this bug report: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1189611
+ UPDATE: Up to kernel 3.13.0-23 a patched working package of
bcmwl-kernel-source 6.20.155.1+bdcom-0ubuntu6 here:
http://notyetthere.org/data/bcmwl-kernel-source_6.20.155.1+bdcom-0ubuntu6_amd64.deb
Currently there is no way to have utopic with an up to date kernel and
properly working BCM4331 chip at the same time.
Looking at the changelog its most likely caused by the update to the new
upstream release in version 6.30.223.30+bdcom.
As of utopic unicorn this is still broken.
