@lesm, As another user mentioned, it appears to be a W11 BUG, and it had to do with SMB protocol.
For instance, if I use the COMMAND PROMPT, I have some NET VIEW issues:
==========================
PS C:\> net view
System error 6118 has occurred.
The list of servers for this workgroup is not currently available
PS C:\>
==========================
Before some W11 Update version it worked perfectly, I'd see my PC, wife's PC, and the Router SHARES..
However, it does work somewhat using SHARE NAMES:
======================
PS C:\> net view \\tp-share
Shared resources at \\tp-share
Share name Type Used as Comment
-------------------------------------------------------------------------------
G Disk
The command completed successfully.
======================
Now if you want FULL ACCESS to that drive on the Router (G:), use NET USE:
=======================
PS C:\> net use v: \\tp-share\g
The command completed successfully.
PS C:\> dir v:
Directory: v:\
Mode LastWriteTime Length Name

PS C:\>
=======================
You now have FULL ACCESS on your PC using V: as the drive letter.
By the way, a network of Windows 10 and Windows 11 PC's all exhibit the same problem, with some minor differences.
