There are a couple of trials you can do to try to pinpoint the problem.
First, if you can run Ethernet cable to the PC running the server, instead of using wireless, do that. Let some games be played and see if the problem can be reproduced on an Ethernet connection. If not, then the issue is specific to the wireless connection. The solution is to not use wireless. I think it is poor service to use something unstable like WiFi for a server anyway.
If that's inconclusive, then disconnect any Ethernet cables connecting other computers or other devices to the BT Hub. If there are any other wireless clients, disconnect them as well. I recommend just disabling wireless in the Hub temporarily to be sure. Then power cycle the Hub by disconnecting the power for a full minute, then reconnecting it. Once your internet connection comes back up, get some games going on the server and see what happens.
If it works in that case, then maybe some other device is causing the problem somehow. I can't say exactly what it might be, but it would be useful to see how this goes.
And I guess I should say running cable is 100% effective in resolving residential WLAN issues. :P
