Hello there - i have scowerd boards so sorry if this is duplicated somewhere.... anyhelp greatly appreciated with following problem! Thanks loads. Ok i have and snow imac running 10.3.3 broadbanded with acatel speedtouch usb modem. Works great. I also have a pb g4 10.3.3 and an airport extreme bs. I am trying to get the pb online so i have plugged eathnet crossover cable from imac to lan port on basestation. i turn imac internet sharing on and pb is online. However its very tempremental and the pb losses internet conectivity all the time + on the imac when i enable internet sharing it goes off if i close system prefs. This is also a sporadic problem. Any ideas? Cheers P.
