Network cuts out randomly

view story

http://askubuntu.com – Yeah, so my WiFi will randomly cut out every 10-45 minutes. I have a Dell Inspiron 1545 and have updated my drivers with sudo apt-get install bcmwl-kernel-source. The issue is specifically with Ubuntu on this computer. The internet works just fine with other devices and computers in the house, and with Windows 7 on this computer. I will provide any information asked for to the best of my ability, though I am kind of new to Ubuntu, and Linux in general. Is there anything I can do about this? (HowTos)
