So last night I booted my xbox 360 and put a disk for a film in, and then turned it off as was going to watch it later. Few hours later I turned my xbxo back on and for some reason was told that I could not be connected to xbox live. So turned it off and back on again, but same thing happened again. So I then did the connection test and all was ok, and then then to sing into xbox live and it signed in ok. I then turned the xbox on and off a few times to check ti was ok, and it signed in ok every time. I then watch a few things from bbc iplayer on it, and there was no problem with the streaming.
Just now I turned my xbox on and get the same issue I had last night, and again did the test and connected ok. Now i'm sure it is nothing to do with my internet connection, as I was still able to access website and watch videos etc. So no point in turning the modem or router off and on again, as everything else is ok and working. I did find this forum thread from the xbox site from april last year http://forums.xbox.com/xbox_forums/x.../t/241532.aspx
As you see people did do the whole router thing ect and still the problem existed.
I'm on VM 20mb line, has anyone else had this issue?
