[Papershop]

Hi, i have trawled the internet to no avail. I am having problems connecting to certain ebsites via safari. Any websites with multimedia is a no go. I can only really acess stuff like forums and google. The page just sticks and the loading sign continues to go rond and round. Also my automatic updates sticks in the middle. I think it is somehting to do with my rouer, which is a sagem sky router which is provided by the isp. i am currently running maxosx 10.4.11 Any one help?

Turn AirPort off and on, disconnect and reconnet to the wireless network and try rebooting your router. You could also clear the Safari cache.
