Jerry sent me the network diagram. I added his upstairs computer based on what he mentioned earlier.

What see is his CATV/Network/Landline is handled by the Cox cable modem. It doesn't appear to have a Wifi Base Station.
Jerry then hardwired (using Ethernet cable) the Visio (or Vizio?) router which from his description is also a Base Station for his WiFi.
Next he hardwired (using Etherner cable) his PC (the one which has the problem with wireless keyboard and WiFi dropping out) to the Vizio router.
The upstairs computer has a WiFi network connection to the Vizio router.
This is what I gathered so far is:
1. The Vizio router provides WiFi service for Jerry's house. The network name (UUID) is VIZIO.
2. The problem computer is has a hardwired Ethernet connection to the Vizio router.
I assume that the printer is connected through the VIZIO WiFi network, has no network problem, and can be accessed from both computers.
I assume that the upstairs computer has no connectivity problems.
Looking at this diagram the problem computer should not be using the WiFi connection, since it has a hardwired Ethernet connection to the router. Enabling WiFi on that computer would create a duplicate network connection to the same router. If you enable both, the wired and WiFi network connection, that might cause issues, WiFi connection should remain turned off on it, but it should still have connectivity to the Internet through the hardwired connection. The earlier screen captures (also shown below) seem to confirm that.
Jerry, the following picture shows that your problem computer has a hard-wired connection to the network called VIZIO, and the WiFi network connection to the wireless network named VIZIO is turned off. In the configuration shown in that picture, your computer should have access to the Internet. Both the wired and WiFi networks are called VIZIO because they originate from the same router. Any device on your network communicating with another device on the network will have to go through the router. That is expected behavior.
Jerry, do you understand how this works?
