I have a home network consisting of the following: * Linksys WRT54G Router, hardware version 1.0 (http://www.linksys.com/products/product.asp?prid=508&scid=35) * XP Home Edition machine with a Linksys Wireless-G PCI Adapter card. * Windows 2000 laptop with a Aterm Warpstar WL54AG PCI card. Up until now, this has all worked absolutely seamlessly. The other day I did a Windows Update manual update, and saw the following: Cisco-Linksys LLC - Networking - Wireless-G PCI Adapter Date last published: 3/26/2005 Linksys, A Division of Cisco Systems, Inc. network software update released on December 22 2004. I installed this update, and since then have had nothing but problems. My connection on the XP machine will drop, and nothing, including rebooting the router, will work. I end up having to reset the router back to its factory settings. I've tried uninstalling the update, and rolling back the driver. Even now, I'm connected, but only to an unencrypted network - and even then, the network icon in my taskbar shows my machine as not connected! Every so often, the connection drops and I have to repair it. Has anyone with Linksys network router/cards had the same problems lately? P.
