Hi! I'm writing here beacuse I have a problem. I have a 27'' iMac: never had a problem since january, but from today my internet (cable) connection works very slow. I thought it was my router, but with my MBP everything is fine: with the iMac I can't nearly reach the SpeedTest site. I tried rebooting, shutting down, resetting the router, changing browser, changing DNS settings: nothing. Also the wireless transfer files between the MBP and the iMac is so slow: yesterday I transfered some video files 1MB/s, today 20 KB/s!!! I've also tried using AirPort in the iMac: nothing. Is like the internet connection is gone. What can I do? Is my iMac broken? Thanks for your answers. Bye! P.S.: as if the above was nothing, I've updated Firefox to 3.6.2 and I can't open it anymore (in my MBP, of course, everything's fine).
