Root More MIUI issues help can't connect to wireless


So after losing a bunch of icons from the home screen I reflashed the rom. It worked great. I didn't tweak anything life is grand. Well this morning I was trying to do a batch app to sd through titanium and i couldn't get root access. So I read on a forum that you just delete super user and you're good. Blah blah blah. Long story short, I can no longer connect to my wireless network. It just get stuck at obtaining IP address. I realize i'm asking dumb questions every few days but I'm at a loss and really don't want to go through the whole delete and re flash process again as my phone has tons of apps and it's a night mare..
