I've been a Windows user since 3.1 but have only recently tried Macs and have a 20" iMac and a more recently bought 15" Powerbook. Both are conneced to my home network of PC through a Vigor ADSL router, the iMac by cable and the PB by wireless<br><br>The PB is running 10.3.9 and everytime it goes to sleep and wakes up it loses connectivity through the wireless network even though it is shown as still being connected.<br><br>Any ideas what I can do to sort this problem?<br><br>Thanks<br><br>Mike<br><br>
