I have a Dell laptop, Win2000, Linksys router, wireless card. All have worked and connected perfectly from January until Saturday, Dec 8. I ran a full virus scan on Dec 7. It found a couple things, fixed them, and I went on like normal. I played online for a little bit, then turned it off on Friday. On Saturday, when I went to startup, I got an error: Regsvr32 Loadlibrary (c:\documents and settings\all users\application data\rgnihadw.dll") failed, Access denied.
I went in search of the rgnihadw.dll file and couldn't find it. It was in quarantine. So, I put it back where it was. Still couldn't connect.
Spent 8 hours online with Linksys trying to figure out if it was a router problem. Bought a new wireless card, to see if that was it. Called my ISP. I even called Dell, even though I bought the computer off ebay. I even connected directly to the cable modem and still couldn't connect.
Weirdly enough, I can see the network. I can see the other computers in our home, connect to them. I can see other networks in our neighborhood.
Throughout all of this, all other wireless computers in our home are FINE! Just *my* computer. I have no idea what happened, or what to do. None of the people I talked with knew what to do.
I would greatly appreciate ANY assistance!
