Ridiculous Disconnects

Since 0.88, I've had d/c problems while doing anything. Luckily, they've slowly fixed most of the things that were d/cing me, and I haven't had any problems keeping a shop up or doing a long grinding session without d/cing in the past week. However, I am STILL d/cing upon switching channels or characters. In fact, EVERY TIME I change channels or characters, I d/c. I have a brief window of like 5 minutes upon starting up the game where I can change channels without getting booted to the login screen and then to my desktop like 5 seconds later. After that, I d/c within 15 seconds of changing channels or characters . No exception. I don't understand why this is happening at all.

I'm fine with changing channels, but if I get a lot of cutscenes and whatnot (ahem, Visitors event), then I DC faster.
