Hi all. I'm a long time lurker who's finally come across an issue I can't solve, so I decided it was time to bite the bullet, and join the forums.

On to the issue. I have a desktop running Vista 32 Ultimate, a laptop running Win7 Ultimate, a printer, and a network. The desktop (Vista) has an Asus P5N32-SLI Premium WiFi-AP Solo motherboard. When I first built it, I needed it to be connected wirelessly to my home network (hence the WiFi-AP Solo bit). I've since relocated this system, and have had it plugged,via ethernet, into my router (Linksys WRT54G2). Until two days ago, I've been able to access my network just fine. This is where things get dicey...

I was testing network compatibility with some older hardware of mine, so I briefly de-secured my network. Unfortunately, in a moment of utter stupidity, I went into my WiFi AP control panel, set it to "Access Point" mode, and cleared out my security settings from there. A moment later, I re-entered the information, but found that my desktop was no longer connected to my home network (Valhalla). I still have internet access, but that's it. With the WiFi antenna attached, I can connect to Valhalla just fine, but not via a direct ethernet connection.

Now, I can still "see" the other devices on my network in the "Network" window, but that's it.

I've tried every solution I can think of: reconfiguring the network via the router webpage, removing & reinstalling all onboard networking devices, and uninstalling the WiFi AP software. All to no avail. It's the weirdest issue I've ever seen.

A sidenote: When I plug my laptop into the router (and disable the wireless adapter just to be sure), it connects to Valhalla just fine. When I check the network map, it shows the laptop connected to my router, connected to the internet. However, when I plug the same cable back into the desktop, the network map shows a connection to a switch, then to the router, and finally the internet. Here's hoping you might have an insight...



If it helps, I've attached the ipconfig.

Not even a "hello"?
