I'm frustrated. I have a Pavilion LK237AV Laptop with a Broadcom 4313GN 802.11 WiFi adapter - Driver dated 5/8/2012, Version 18.104.22.168; as far as I can see from HP's site, this is the latest. In the last month when I try Windows Update to look for udates, it hangs. I reboot, and it Has found an update! (Usually MS Security Essentials). When I start to download this, it gets to 99% and sticks there. I don't get the problem if I use the LAN adapter, but this is not convenient with my topology.
