You gave me an idea. The machine I'm using and one of my laptops are also my test machines, where I plug in random wireless devices, check if they work, and then either put them back in the box, or deliver to a customer. If the device came with an insallation/uninstallation program, I would usually uninstall the driver. So, I go unto: Rt Clik on My Computah -> Properties -> Hardware -> Device Manager and View -> show hidden devices (This is the same as your command line incantations) It was showing a huge number of ancient devices and duplicates, many of which are long gone. Some of the duplicates are obvious entries for the same device, walking through multiple USB ports. My printer collection is also a mess for similar reasons. Equally irritating are entries from mulitiple anti-virus products and multiple AVG versions. What a mess.

Thanks for the reminder and have a nice day after the Day of the Turkeys. -- Jeff Liebermann jeffl(a)cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

Are you sure the initial connection is real and working? Windows XP has a problem in that it can report an initial connection that doeesn't actually exist, which then seems to later break. I haven't fully verified this, but one way it seems to happen is when Windows XP is shut down or put to sleep or hibernation. Then when Windows XP wakes up it thinks it's still got a working DHCP lease, but that lease has been idled out by the wireless access point. Eventually Windows XP figures out that it doesn't actually have a connection. Try disconnecting from the wireless before shutting down, sleeping, or hibernating, and see if that affects the problem when Windows XP start back up. Also check your logs to see if some error is being logged when this happens. -- Best regards, FAQ for Wireless Internet: <http://wireless.navas.us> John Navas FAQ for Wi-Fi: <http://wireless.navas.us/wiki/Wi-Fi> Wi-Fi How To: <http://wireless.navas.us/wiki/Wi-Fi_HowTo> Fixes to Wi-Fi Problems: <http://wireless.navas.us/wiki/Wi-Fi_Fixes> |
