Hello,
Thank you for posting in Microsoft Community forum.
It sounds like you figured out the issue—enabling SMB 1.0/CIFS File Sharing Support resolved it for you. For others encountering similar problems, here’s a step-by-step explanation of why this happens and how to fix it:
Why the Issue Occurs
Windows 10 and 11 have SMB 1.0 (Server Message Block) protocol disabled by default for security reasons. Many older routers use SMB 1.0 for file sharing, so if SMB 1.0 is not enabled on your computer, it won't be able to access the network drive connected to the router.
How to Enable SMB 1.0/CIFS File Sharing Support
Here’s how you can enable it:
- Open Control Panel:
Press Windows + S, type Control Panel, and open it.
- Go to Programs and Features:
Click on Programs → Programs and Features → Turn Windows features on or off (on the left panel).
- Enable SMB 1.0:
Scroll down and locate SMB 1.0/CIFS File Sharing Support.
Check the box next to it.
Click OK and let Windows apply the changes.
- Restart Your Computer:
Reboot your computer to apply the settings.
- Retry Accessing the USB HDD:
Open File Explorer and type the address of your USB HDD (e.g., \192.168.x.x\sharename).
Important Notes
Security Implications: SMB 1.0 is an outdated and less secure protocol. If your router supports newer versions of SMB (like SMB 2.0 or SMB 3.0), consider upgrading your router or updating its firmware instead.
Alternatives: If enabling SMB 1.0 isn’t ideal, look for firmware updates for your Linksys router or use other methods like FTP or DLNA if your router supports them.
If you still encounter issues, let me know! I can help troubleshoot further. 😊
