Connection issues may be related to the default access rules on your router or the maximum number of connections allowed by the router itself If the router reaches its maximum number of connections, it may refuse subsequent connection attempts.

I seem to have the same problem James was having. I only have two direct connections to my NetGear WRN2000 router plus a laptop on WiFi so I don't think I am exceeding the number of allowed connections. I looked at opening up the ports as per your instructions, but they were already open. Any other suggestions? Things were working correctly until about 2 weeks ago.
