I am posting this for a friend. He currently uses his cellphone, connected via USB to his pc for internet (it is faster then his internet). He was getting the 916 servers full error constantly. I turned off his windows firewall, disabled and stopped the service after. He was able to connect and all was fine. The next day I log on and join his game, and right as we start zoning into mines, he d/c's and is unable to get back in with the 916 error. I went in and enabled and started the firewall service, but did not turn it on, as sometimes Windows requires the service to be running, and I am not familiar with the software he is using to tether his internet, to know if its required. Since then, he now gets 906 in game "patch server connection failed" I can get in fine so I know its not under maintenance. I have rebooted the pc and had him reboot his phone many times (I'm doing all this remotely).
Have any of you ran into this before, or have any other ideas?
His pc is Windows 7 64 bit and I have him using Sophos home AV (I use this too with no issues).
