What makes you think it is related to you Linksys wireless connection?
Did this start after setting up a Linksys wireless network?
I'm having the exact same problem as the original author with my LinkSys PCI wireless 802.11g adapter, WMP54G. The error is: "WMP54Gv4.exe - Application Error" "The instruction at "some-hex-address"" referenced memory at "the-same-hex-address". The memory could not be read."
My PC is connected to the wireless router by the LinkSys wmp54g connection. However, I have tried a cat6 connection directly into one of the 10/100 ports. The error does not occur when I use the direct connection and disable the wireless connection, but that's not a practical permanent solution due to the location I need to keep my router to server the rest of the house.
The problem started after I installed the LinkSys driver on my XP Pro SP2 system and set up the Wireless network using the LinkSys Wireless Connection Monitor v4.3. The wireless network works fine, I don't get any blue screens and my connectivity is solid but the error occurs every time I log off or shut down and requires manual intervention.
If the computer has a wireless card, then check with Linksys to see if there is an updated driver. If the computer is attached to the router by cable, then it is probably a different problem, since the router usually doesn't install anything on the "host" computer.
I've updated the firmware as well as the driver with the latest available at the LinkSys site as of 11/18/2005. LinkSys "LiveChat" support was no help and they suggested that XP Pro SP2 as the problem-- even though I have no problems with any other hardware or software except for the LinkSys wmp54g driver.
Any other ideas?
