I was being DCd constantly. Within 2 minutes of logging in, during leaves, during behests and ODDLY around 11PM every night. Getting the dreaded 30002 an error occurred on the server message. I posted multiple messages to the bugs/tech support forums and tried every possible fix i found out in the web world. Turned off this service, that service, upgraded firmware... so on and so on. NOTHING WORKED!
Until now
In a last ditch effort I decided to upgrade my wireless G router. I went out a dropped $140 on the best NETGEAR N Router I could find at Best Buy and ever since then... not one... single... drop.
To add...
I went from 2% packet loss to 0% packet loss (pingtest.net) <-- maybe this is the key
I have full windows firewall running.
I have full virus scan running.
I have not disabled a single service.
I am playing over wireless.
I am running in windowed mode.
I am playing on a laptop.
Been running stable with 0 DCs for the last week. And I assure you... I was DCing 3 times a night, so the likelihood of this being a fluke is low.
Hope this helps someone else out in 30002 land... cuz I was very close to dropping this game... perhaps this will walk YOU back from the edge as well.
