Alright I have a big problem with my gateway laptop, I'm posting this from my PC. Here is my problem, it wont let me connect to the internet with the wireless connection and it seems like my wireless connection in my whole house is down due to this one computer. Its up and running but no computers can connect to it. The laptop also can not connect to the internet using a cable from a internet jack. No clue on how to fix this. I've done everything I think is possible, please help!
Also is there anyway to reinstall windows complete without using a disk? I do not have one.
