Broadcom BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01) does not connect

Question

I have a fresh install of Ubuntu 14.04 on an HP Pavilion DM4 1200. I can see all of the local SSID's in my area including my own. However when I provide my WPA Personal key to login into my wireless Apple Router it does not authenticate and times out. I can connect via Ethernet.

I have searched many of the Ubuntu solutions including building and updating the more recent Broadcom STA driver without success. I have updated the installation. I haven't found this specific issue and would appreciate being led in the corrective direction.

Maybe this helps: https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/251650

• forcing the wireless router to use wireless-G (54 Mbps) speeds for troubleshooting purposes
• changing the access point name from "FRITZ!Box 6320 v2 Cable" to fritzbox without any special characters or spaces in the SSID name.

Then reboot the router and your PC and retest wireless.

• Also changing to wireless channel 11 in your router will help.
