I've now installed Win7 Pro on a number of machines. Early on they frequently lose the network, but eventually settle down. We have a Lenovo Thinkpad in the office that regularly loses the network to the point that its user has given up on it. I've brought it home and have encountered the same problems. Both home and office networks have a TrendNet637 access point and the lenovo is connected wirelessly. Sometimes I find the wireless capability of the lenovo turned off. In other cases I am prompted to turn on file sharing again. These problems occur despite that machine simply sits there without being used. Any ideas? I will also contact the lenovo people.

Hi Karl, Thanks for the post! How about using wired connection? Does it loss network frequently? I recommend you update the wireless card driver and BIOS to the latest one to see if the issue persists.
