I have two new notebooks with the following specs: System 15.4" 1280x800 - nVidia GeForce Go 8600 GT 512MB Processor Dual-Core Intel Core 2 Duo T7500 2.20GHz 800FSB 4MB Cache Memory 2 x 2GB PC5300 667MHz DDR2 SODIMM Optical Drive DVD-RW Optical Drive Hard Drive(s) 120GB 7200RPM Serial ATA Notebook Drive Mini-PCIe Expansion Card Intel PRO/Wireless 3945ABG Network Adapter Operating System Vista Ultimate Everything is fine except one problem. When you can't access the wireless access point because you unplug it or because your remove the ip address from the connection properties, the os locks up.I have the latest drives from Intel. When you can connect to the access point everythin is fine. As a test to verify, I unplug the access point and both notebooks locked up. Is it a card or software problem? Thanks
