Hi all,
I’m facing the error as in the subject when trying to copy any file from my USB stick inserted into the router via network sharing (LAN). I found this page, but the proposed solution isn't suitable for me because the file isn't encrypted or signed. Furthermore, it's not even large and the issue affects any file.

Sorry, I don’t understand what you mean. Is that a solution?

You have provided minimal details of your problem; you have not told us what kind of file you're copying or what happens when you try other files. Is this the only file you are having the problem with?

Try disabling SMB signing.

From an administrative PowerShell session:
Powershell: 
Set-SmbClientConfiguration -EnableSecuritySignature $false -RequireSecuritySignature $false
Set-SmbServerConfiguration -EnableSecuritySignature $false -RequireSecuritySignature $false

Actually I had already specified this thing:

So, these files can be images, pdf documents, etc.

Unfortunately it didn't work.

Error code 0x80090006 means "Invalid Signature" and typically happens during large file copies over network shares (SMB).

Usually triggered when security software or network hardware interferes with data packet signing.

Third-party security tools (like Symantec Endpoint Protection) can block or misinterpret signed data streams during heavy transfers. Temporarily disabling your security suite or turning off intrusion prevention (IPS) features often resolves the issue.

Network driver features like Large Send Offload (LSO) can cause TCP flows to become out-of-sync on file copies. Disable Large Send Offload for IPv4 and IPv6 in your network adapter properties fixes SMB transfer failures.

Running an integrity check via Command Prompt (sfc /scannow) can repair system components causing signature verification failures.

I don’t use third-party security tools, and as I wrote the issue is also related to a single small file such as jpeg, pdf, etc.
sfc /scannow doesn’t show errors.

Have you tried a different USB stick? Is the problem with any USB drive you connect to the router?

Hi guys,
I have to correct my previous answer: pseymour's solution was valid. The computer just needed to be restarted.

Thanks everyone.

Nice. Out of curiosity, did you have a drive mapped on your PC to the router USB drive?

Hi, I’m not sure I fully understood—and I apologize if I’m not an expert—but to answer your question: I assume so. I don’t recall the exact steps I took, but what I can say is that I open File Explorer, go to "Network," and in the pane that appears, I find my router’s name (iliadbox_Server) under the "Computer" heading. Once I click on it, I can access the files on the USB drive connected to the router.
What exactly were you trying to find out? :)

I meant did you have a drive letter, for example U:, mapped to the remote USB drive, so you could access it by the letter. It sounds like not. 👍🏻

Oh, ok, so I think not: if I go into the path I cannot see any drive letter.
But if it was mapped, what would have changed? Is it related to the problem?

I was wondering if you needed the reboot because it was a mapped drive. Sounds like you don’t use a mapped drive, so I’ll probably include a “restart the computer” the next time someone has this issue.

Also, anyone who stumbles across this from a search will see they have to reboot, so we’re helping future folks.
