Bad connection issues...

Yes I should post this on tech support. But i have, and now i'm going to ask you guys. Because it's driving me insane ><

I've recently been downloading UI's. Ever since I have, i've been getting weird connection issues. Net crashing whenever i turn in a quest. etc etc, so i reinstalled. This morning, with my new UI, it was working fine. Then, all of the sudden, i log off for a couple hours.

I log back on my level 27 mage in Orgrimmar, and it doesn't let me do anything, quits me out emedietly, disconnected from server (not net, just server). So then i delete my UI folder, and my WTF folders. I try to log back on, same thing. Reboot, log on my level 60 rogue (yune) in tarren mill, she's fine, everything is fine. I just can't log on my mage for some reason. I tried to log on a different server, on a level 11 priest in tirisfall glades, lagged out emedietly. I don't know what the heck is going on, but has anyone had this problem before? Solutions would be much appreciated, as this is driving me insane ^_^

I've been under 100ms since they did their so-called server upgrades.
