Windows 10: Just installed windows 11 on laptop- windows is not detecting any networking hardware

Full disclosure: Wireless internet connection was already a problem before installing windows 11. Prior to installation, the wireless network adapter was missing not showing up, hidden or otherwise, in device manager. This problem is what prompted me to install windows 11. Install was a success- the proper drivers are there, but now it says that windows is not detecting any networking hardware. The laptop in question see specs below is very lightly used and is only a year old. Seems unlikely that something physical happened to the network adapter hardware. Is there anything I can do, short

Windows 7 x64 not detecting GTX295

Background
I installed the 295 and it was not detected. So I downloaded 181.22 for Vista x64, but those drivers didn't work for gaming (CTD). So I installed a GTX 8800 and it was detected and drivers installed automatically from Windows Update.

Now I put the 295 back in, and it installed and was able to run games. However, the nVidia control panel was not available, suggesting that the drivers hadn't installed properly... So I deleted the drivers and rebooted. And... again it lists my 295 as a "Standard VGA Graphics Adapter" and a "3D Video Controler", but no drivers can be found by Windows Update.

Question
1) Is there anywhere I can download the Windows 7 x64 drivers and install them manually?

2) Any idea how I can get Windows 7 to recognize my GTX295 so that it can download the proper drivers.

3) Have you had the GTX295 install automatically in Windows 7 x64?

 

Windows 10 "No Networking Hardware Detected"

After the Windows 10 upgrade from 8.1 pro, I have no network connection. The machine is an old HP Media Center PC.

Clicking Connect to a Network give the error: No Networking Hardware Detected

The on-board Intel PRO/100 VE Network Adapter does NOT appear in Device Manager, and there are also no "unknown" devices appearing.

HP offers no driver updates after XP. However, Windows 8.1 connected to it with no trouble.

Even if I had a driver to install, there is no networking hardware detected.

I am confounded. Can anyone please suggest a solution?
