Accurately what devices are listed under the Network Adapters in Device Manager? What, if any, caution or errors are in Device Manager? What connections are revealed in Network Connections? Are they all enabled?

Device manager demonstrate the network card - Realtek RTL8168C (p)/8111C with no advice or errors. Network connections also show the same card below LAN - Local area connection - unknown network.
Thanks

"Device manager shows the wireless device is working." Now only your Ethernet adapter is present. What model is your wireless card? Have you followed the commands? Frequently you are imaginary to run the setup program and then actually install the card when prompted. Try the installation again.

Sorry, that is truly my wireless network card, even though it is showing as Ethernet - I don't recognize why. It is a Sitecom Wireless Network PCI card 54G Turbo. The software was installed in the computer before plugging in the card. I have also tried reinstalling it numerous times.
Thank you for your continued interest.
