Do you have mods that log data? For WWS, or stuff like Recount/DPS meters. If you do try turning them off.

If you run too many damage meters or mods that try to sync with other mods, what you describe can happen. The mod will flood a certain channel with ALOT of data, to the point where you will DC. If you attempt to log back in the flood continues and you get kicked out again.

OK. An update. I found out that its impossible to raid on 60.50, 60.53, and perhaps others. These IPs won't give you any lag when you're running around, but if you zone into raids, you will DC. I DCed on MH trash until I switched IPs around.

Workable IPs are 60.48, 60.49, 218.111.
