Can't get into my GUI >.< !

[Anthony]

I could before . . and now i gotta enter a username and password. I put "admin" in both fields, and it still doesn't work. I've tried a bunch of combinations with just "admin" for username, etc, and it still didn't let me in. I was having an issue with my internet light being red. Very weird. Really wanna know what's going on and how to fix it if it happens again. (i got my internet to work somewhat, hopefully it stabilizes for this message lol)
