I have had 11 disconnects with a 90002 error in the last 4 hours. That's not counting the number of times I lagged out for ~10 seconds but didn't get disconnected and recovered.

I didn't have this problem prior to the past week, and nothing has changed on my end. And the only thing I'm being disconnected from is FFXIV, my internet remains connected for everything else even while I'm being dropped from FFXIV.
