[ubuntu] Issues Connecting to Wifi

view story

http://ubuntuforums.org – Hello I am very new to Ubuntu, I recently installed Ubuntu 12.10 on my HP 2000 Notebook PC. I am having problems connecting to my router. At times it connects and at other times it doesn't, the behavior is very odd but now it's on a streak of not connecting. I have ran numerous commands that I have found in other threads with the same issue to no avail. I'm hoping I can get some help here, thanks in advance (Hardware)
