Title:
offer 6.20.155.1 build in trusty
Status in “bcmwl” package in Ubuntu:
Incomplete
Bug description:
As opposed to open-source software, proprietary software has the USP
that newer versions are not always better. This seems to be the case
for the 6.30.223.141 driver which offers considerably worse
performance for many users than its predecessor 6.20.155.1. This
assumption is based on the reactions
<https://plus.google.com/+NickGroenen/posts/HF828QcPK6k> to
instructions for a "forthport" of 6.20.155.1 to saucy
<https://zoni.nl/posts/2013/11/09/fixing-the-broadcom-bcm4331
-wireless-drivers-on-ubuntu-1310/>.
Please continue to provide older BCM packages in the tree to make it
easier for users to switch.
