Comment 37 for bug 1159306

This bug prevents me from connecting to some wireless routers. Please set the importance as high prority and assigne it to someone.

I am using Ubuntu 14.04 (3.13.0-40-generic x86_64), my laptop has BCM4313 (as lspci reports), and I am using latest bcmwl-kernel-source driver (6.30.223.248+bdcom-0ubuntu0.1).

Since it is an issue in Ubuntu 14.04 LTS, and it prevent connecting to WiFi router, it is a critical bug, and it needed to be fixed even if it is a kernel issue.
