Dell TrueMobile 1150 Series Mini PCI Card is the wireless adaptor in my Dell C640 Latitude laptop - with the version of the drive that ships with the computer I found that my home connection was v.unreliable - I'm using a no-name USB wireless adaptor on the server at home and running it in peer-to-peer (ad-hoc) mode. Untill the weekend it would take several changes of channel and re-boots to get the two talking. However, with the current driver (v.7.86.15.638.A22 - how do they number things!) all is well. It finds the server as soon as it boots and I can get all the way to the end of the garden (small garden!).
