Can't connect to router-attached HDD (shared drive)


Run both these commands in PowerShell,

Set-SmbClientConfiguration -RequireSecuritySignature $false

Set-SmbClientConfiguration -RequireSecuritySignature $false

They’re identicle commands.

Run both these commands in PowerShell,

Set-SmbClientConfiguration -RequireSecuritySignature $false

Set-SmbClientConfiguration -RequireSecuritySignature $false
Those commands are identical. If you meant to also run Set-SmbServerConfiguration, that is not necessary unless the 24H2 machine is acting as a server.

@antspants You're on 23H2, which doesn't require SMB signing by default. You can enable though if you're nuts.
I'm just now getting back to this issue. 'Life' got in the way.

Please clarify for me which Power Shell command, if any, I should try? My old brain (70 y/o) got a little confused with the conflicting "SmbClientConfiguration"posts.

BTW, if it helps: I now have TWO PCs on the network with the same problem. Both are 24H2. A 3rd PC which is 23H2 can still access the shared drive.

You're going to need
Powershell:
Set-SmbClientConfiguration -RequireSecuritySignature $false
almost assuredly, because your router very likely does not support signing. You would need the insecure guest logon command above if you're not using a username and password, but it sounds like you are.

  1. Run the PowerShell command I just gave.
  2. Open Credential Manager, and add a Windows credential for your router, specifying the router name or address, and your username and password.
  3. See what the situation is after those two things.

Ran the PS command on both PCs. Had to add a credential on one, the other already had one, it was the older Win 11 PC that all this worked on before the 24H2 update.

Uncertain these will help but attaching a sreenshot of the error message.
error msg2.webp

I also set these services: Function Discovery Provider Host, Function Discovery Resource Publication, SSDP Discovery and UPnP Device Host to Auto run based on a post on a Microsoft Answers page at Redirecting. I ended up there after using the Diagnose command. Didn't help.

Hallelujah!!

Got it!
Ended up on the post below through a link on the Microsoft Answer site post I LINKED TO ABOVE.


Here's what worked:

"Computer Configuration, Windows Settings, Local Policies, Security Options
Double click on Microsoft Network Client: Digitally sign communications (always)
Double click on Microsoft Network Client: Digitally sign communications (if server agrees)
Set both of these to "Disabled"
Click on OK."

Implemented the 2 items and POOF! Am able to reach my router/shared drive. Caveat: I have no clue if theses 2 settings, in combo with god knows how many win 11 settings, is what worked. Or, were these 2 items alone a good fix? I'll take the win. I'll give it a few days before I mark this thread Resolved.

Big thanks to everyone who helped! :-)

FTP also works, but if you enable TLS for security, then you'll need to use FileZilla. In the address bar of File Explorer, as long as TLS is disabled I can paste ftp:// followed by the router's IP. WAN access is still disabled by default so you can experiment.
