Networking :: Shares No Longer Visible Can't See Other Shares

I just switched to a new router (from DLink DIR-655 to TP-Link Archer C7) and now my Windows 10 Pro cannot see network shares nor can others on the network see its shares. Prior to the router switch, it could see shares and others could see the shares it exposed.

The Win10Pro can see the internet. I can still ping other computers and they can ping the Win10Pro, just no Windows sharing. All computers are in the same Workgroup. I am not using a Homegroup; computer connections are made with user accounts.

The Windows 10 Pro is connected via wire. When I made the switch, I remember that Win10 came up and told me it had a new network and prompted whether to allow network discovery - to which I said yes. I thought that odd at the time since changing the router didn't change the NIC connection from the Win10 -- but whatever. However, it did change the IP address on the Win10Pro from what it was. But I've since rebooted all computers (thinking that might cause them to refresh) but no improvement.

Advanced Sharing Settings are set as:

Private: Network Discover = ON, File and Printer Sharing = ONAll Networks: Password Protected Sharing = ON, Public Folder Sharing = ON
