Problem staying logged in

[icogs]

I keep getting randomly disconnected from the game while playing for no apparent reason. Sometimes it's isolated, happening once an hour or so. Others I get disconnected in succession right after logging back on from a disconnect. It's getting annoying because dungeon groups have wiped because I, the tank, dc'd at the key moment.

Yes, I installed everything correctly, deleted WDB, changed realmlist to west, north, east and even triple checked. Nothing helped.

Are there any ports I need to open for this game to run properly?

What is your average latency?
High latency + movement can result in false positives anticheat kicks.

It's around 180-220ms. I thought that bracket was considered good latency.
