Home Network Issues

Hey guys, I'm new here hoping for a solution.

Basically what happened was starting this morning, I can no longer see other computers that are in my workgroup. There are three computers, two computers can see/talk to each other except my computer (main) which cannot see any computer. All computers have internet and none have a firewall installed. All computers are networked to a router. The router has been replaced as a attempt to solve the problem. Here are some screenshots to help.







All 3 computers have the "Node Type" of "Unknown ".

So give me your thoughts!

 

First thing I suggest you try is to remove the QoS scheduler:

Can you tell me how to uninstall it?

 

This site shows how you can disable QoS Scheduler:

Personally, I'd uninstall it completely. You do that in the same screen, but instead of just taking the tick out of the box, you highlight the item QoS Scheduler and click on the Uninstall button.
