Thanks, but I did click the " share your internet connection with Airport equipped computers"...<br><br>It is funny, but my powerbook tries to establish a connection with my iMac, until it times out after a minute. It wont even try to establish if I change some of the other settings...<br><br>I am wondering if I need a second IP address from my internet provider Shaw Cable?<br><br>thanks for your help....<br><br>
