Windows 10: Win 11 does not show modem/router or other network computers in File Explorer

Hi,Replaced Archer VR6100 modem/router with a VX220 mid-December.Network working perfectly before 22H2 updates 10/11 boxes.All boxes same workgroup, private network, discovery and sharing permitted without a password. All have fixed IP addresses, permanently assigned in router and MAC addresses permitted.Every device can ping each other successfully, however, the Win 11 box refuses to show up other computers or even the modem/router in 'Network" in 'File Explorer'.Can access the shared drives/folders on the Win 11 box from any Win 10 boxes, but I can't access shared drives and folders on the

Computers not showing up under Network in Files Explorer

Installed a new modem/router combo, now none of the local network computers show up under Network in Files Explorer. I have a Pro tablet, a laptop, and 2 desktops on the home network.
I am "guessing" it has to do with some modem setting, not a clue where to start looking. This is a new situation for me.

 

Win 7 and Win 10 on network

I have home network with separate modem, router, and WAP's. My Windows 7 computer does NOT list the Windows 10 computers on network computer list but the Windows 10 computers network list DO list the Windows 7 computer.

Turned off firewalls, gave permissions, shared drives. Nothing allows Win 7 computer to access the Win 10 computers.

Any suggestions for a fix?

@Samuria: I can ping all 3 other machines - All machines are running Windows 10 17134.5




@slicendice - all are set to Private Network
@Jimbo: SMB 1.0 enables




I have gotten this far, but nothing seems to be working. At one point after installing the router the machines did show up in the Files Explorer, now nothing.

Thanks for the replies. After I get the new router/modem in place and get all the cables "neatized", I'll return to this issue.
