The Dreaded Error 90000

Earlier today I couldn't log in due to the over 90000 error, and I had to restart my router and modem due to having other internet issues as well (certain pages wouldn't load, etc) and after the restart, I got on no problem.

Here's the thing, after playing for 3-4 hours with only 2 or 3 lag spikes, which other people were getting, I have been kicked off. When I log back in, I get kicked off within seconds. The weirdest part of it all is that my wife is connecting to my computer for her internet, and she's not getting disconnected at all nor has she experienced any of the lag spikes that I have.

What's the dealio?

Edit: I neglected to mention I'm on Hyperion.
