Hi all, this is driving me crazy now!! I have had a fair few problems with this in the past but always managed to get it back but having no such luck this time..
Everything has been going smoothly for about 2 months without the dreaded message. However, I moved my server (iMac) upstairs from downstairs and constantly getting this message. I have bought home plugs today as the wifi is slower upstairs. That's dramatically increased the speed but still not sorted my problem.
I just tried turning UPnP off, restarting the router, then turning UPnP on and restarting the router, then restarting the iMac and everything was fine (for about 15-20 mins) and then I get the same message.
I have tried manually specifying the port (and on the router) but makes no difference.
I have downloaded my logs but not sure which one to post..
ANY HELP WOULD BE VERY MUCH APPRECIATED. I FEEL LIKE THROWING SOMETHING OUT OF THE WINDOW BUT I DON'T KNOW WHETHER IT SHOULD BE THE IMAC OR ROUTER! :(
