Same issue. Constantly getting disconnected with Error 90006 since yesterday afternoon. the game will only let me get as far as getting on before pretty much instantly kicking me off. Been happening since the hotfix and despite what the updates on yesterdays PSN issues say about it being fixed, it is not. And I do not have the time to try uninstalling and reinstalling the game as it would take 15-20 hours for it to update.

Only thing thing I know about my internet provider is that it is Century Link. Don't know anything about the router or anything else. And I am located in the Mountain time zone, Colorado.
