Upstairs, I have a desktop and a laptop. They are connected to my wife's computer, downstairs, via wireless. Both my wife's downstairs computer and my laptop, upstairs, will connect to the internet just fine, but the desktop will not, even though it shows that there is a strong signal being received. I am running Windows XP Pro, version 5.1.2600, with SP2. It has 256 MB of system memory. The computer has an AMD Athlon chip. It used to be a Tiny computer, but after having a major meltdown, about two years ago, I took it to a repair shop, and they installed an ASRock I/O K7S41GX motherboard, as well as a new power supply, so I don't really know what to call my computer, now. I guess it's just sort of a mongrel, Heinz 57 Variety.
I have tried using System Restore, but it won't allow me to restore to a former point, no matter how far back in time I go.
I started it up in safe mode, then ran AVG, but no viruses were found.
When I go to Control Panel, then "Network Connections," it shows that the wireless network is up and running. Even so, I tried repairing the network, by right-clicking on "Repair," but got the following message: "Windows could not finish repairing the problem, because the following action could not be completed: Failed to query TCP/IP settings of the connection. Cannot proceed. For assistance, contact the person who manages your network."
Unfortunately, that person is me, who is totally clueless, and cannot help myself in yet one more area of life.
I have tried going to "Start," then "Run," typed in "cmd," hit "Enter," then typed in "netsh winsock reset" then "Enter," then typed in "netsh int ip reset c:\resetlog.txt" then hit "Enter," again, then rebooted...all to no avail.
Swearing didn't work, and neither did praying, so now I'm out of ideas.
