indicate problems with:
1) Operating system anomalies, virus and or spyware infestations.
2) Incompatible hardware/ software.
I might try to install on another machine before opting for a new card. Elsewise make sure you are clean of vermin.
I bought a Linksys WPC55AG Wireless Network Adapter card from Dell, for use with an Inspiron 8000 running Win ME. I have had nothing but trouble with it.
The installation software generates an error msg "Access Violation at Address 78003B5D, module MSVCRT.DLL, write address 008C0130".
Linksys Tech Support had me on the phone for over an hour installing, uninstalling, and reinstalling. Finally their second-level tech support person decided that the problem must be Microsoft's fault because MSVCRT.DLL is part of the o/s.
I checked the file. There is nothing wrong with it. It is the same genuine original uncorrupted file that came with the o/s.
All this was before actually inserting the card into the computer.
Despite the error msg, the installation did seem to work--I think. But the card doesn't. It recognizes the existence of the wireless network in my office (the router sits about 5 feet from my desk) but won't connect to it.
The software on the installation disk is called version 1.2 and is dated Nov 1994. The Linksys web site offers 2 older versions of the software called 1.1 and 1.2 (but that "1.2" is NOT the same as the one on the disk.) I tried both. Neither threw the error msg, but neither even recognized the network, let alone connected to it.
I spent most of an hour in an online chat with a Dell tech support person--a raw rookie who has no idea what MSVCRT.DLL is!
Is there a fix? Is there a different dual band card that would work with my computer?
