My wireless network at home was working great...until a couple days ago. I had some family over for Christmas and they were trying to help me change it so that I could use my own password to get onto the network instead of putting in the long WEP key (or whatever it's called).

Anyway, so now I can get my wireless to work ok until I restart my computer. Then I have to connect it to my ethernet cable and set up a new wireless connection each time. It has to be something with my computer because I know that my network is working fine. I can use the wi-fi on my phone and PS3 anytime with no problems...So what can I do about my computer?
