Ubuntu boots up and doesn't find any available wireless network and it doesn't recognize my wireless card either. However, when I open the terminal and type: sudo modprobe b43 it finds my wireless card and all of the available networks around me and everything is cool... until I shutdown my system.

When I shutdown and then turn my computer back on it completely forgets about the network I just found and told it to connect automatically to. So, back to the terminal to find the wireless card and networks manually. Every. Single. Time.

How do I configure my system so that I don't have to manually find the wireless card and connect to my network every time I restart my computer?

OUTPUT from TERMINAL:

root@jake-XPS-M1530:/home/jake# dmesg | grep b43
[    8.684953] b43-phy0: Broadcom 4312 WLAN found (core revision 15)

Run echo b43 | sudo tee -a /etc/modules. That should make sure the b43 module gets autoloaded, and your wifi should work after shutdowns.

should I run that in root terminal? –  Jake Newkirk Aug 26 '13 at 0:30
    
You don't have to. Running is as a user with admin rights should work as well. –  mikewhatever Aug 26 '13 at 1:07
    
I opened a terminal and ran the code. I restarted my system and it still doesn't automatically connect. –  Jake Newkirk Aug 26 '13 at 1:22
    
That's odd. Check that it got added to /etc/modules with cat /etc/modules. –  mikewhatever Aug 26 '13 at 7:07
    
This is what it shows after I execute the command cat /etc/modules root@jake-XPS-M1530:/home/jake# cat /etc/modules # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. lp rtc b43 b43 b43 b43 b43 root@jake-XPS-M1530:/home/jake# –  Jake Newkirk Aug 27 '13 at 3:17
