For your own sake don't start messing with your routers and re-installing over and over. If you didn't change anything to get this 3001 error than chances are it's not your network. SE is feeding you the same line they give everyone when they break stuff. I already sent them proof of the latency problems on JP routers and gave them till 6/30 to resolve it. This is an issue with Comcasts routing through to SE. SE need's to get on the phone and figure out issue or look into servers to see what changed on last major update. Do searches or for some of us this happened before and the same response from SE was given. They seem to want people to stop giving them money.

* And just so if a SE rep chimes in and says it's port forwarding. No it's not. It's only to certain servers not characters. All characters will get caught in that zone. It happens across all platforms. It does not happen on NON Comcast isp as far as can be told as of now.
