wifi won't stay connected

Question

I have a HP Pavillion dv6000 with Ubuntu 14.04 LTS and a Broadcom wireless card (BCM4312).

My Ethernet connection is fine. But when the wifi is turned on, it will stay connected for a short time and then disconnect and reconnect again. The wireless card is supposed to use the b43 driver, but it still does not hold the connection.

How can I fix my WiFi problem?

The output from the diagnostic script: http://paste.ubuntu.com/10988134/

Please run the script that is in the accepted answer in the link below so we may see the information needed to help diagnose the issue. http://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work- what-can-i-do — Wild Man, May 04 '15 at 22:01

If it does not work properly after reinstalling the b43 driver then post a new script file so we can see what is going on using the b43 driver. Thanks — Wild Man, May 10 '15 at 16:35

Please do:

sudo apt-get purge bcmwl-kernel-source

the above command will remove the wl driver that is the wrong driver for your device. The next command installs the b43 driver that your device needs.

sudo apt-get install firmware-b43-installer

Reboot

Go into network manager and remove wireless connections then reboot and set the settings to match the screenshots. DNS SETTINGS IPV6 SETTINGS

Also reboot your router.

Well... I appreciate all the help. I ran the above script and and did the reboot and the same thing keeps happening. I have no idea what to do after doing this several times. I am at this computer all the time and apologize for my delay in also returning my results. I don't get it??? – Ted Tarant May 16 '15 at 18:45

Dear Wild Man, Thank you so much for the last set of instructions. It is now holding the connection, however when I changed the METHOD to: DHCP address's only, I could not connect to the internet. So I changed it to DHCP and I am now on the web holding the wifi connection. You have stuck with me to get here(fixed) and it is so well appreciate, and most of all I learned alot about my computer, Ubuntu and the GREAT support. I look forward to helping someone else. Now I hope people that use the Broadcom b43 driver can use this vital information. THANKS WILD MAN !!! ted – Ted Tarant May 17 '15 at 17:56
