Hi there! I've been having much difficulty finding the solution to my problem, so hopefully you guys can help. I just recently did a firmware upgrade on my Lynksys WRT54GSv4 router, and have been having problems with getting it to work. It asks for username and password, and it doesn't seem to recognize them. I've tried every possible combination of a user name and a password that I can think of, but it won't let me back on. Is there a way to go back and reset it? It said that the upgrade was successful, but I just can't log back on. It won't let me connect to the internet, and there are 4 other people in my household who are using it to connect to their computers. The firmware upgrade I used was: WRT54GS-v4_1.06.3.002_fw Any help would be tremendous! Thanks!
