Windows 10: Since the Win 11 update 24H2, my PC won't connect to Synology NAS.

Error = MS Windows Network: "The local device name is already in use"I have tried connecting from other PC's in the house & all is OK. Error is manifesting itself since the upgrade. I have tried disconnecting drive & reconnecting - no joy. I can access the NAS and files from console via Edge browser. Is this is a known problem? How can I fix please?Many thanks for your insights..Dino

W11 Pro PC Unable to Access Synology NAS

Thank you for reaching out. One possible reason for this issue could be that the Windows 11 PC is not able to authenticate with the Synology NAS or the Windows 10 PC due to a network configuration issue. Here are some steps you can try to resolve the issue:



1. Try accessing the Synology NAS using the IP address instead of the hostname. (can you open the Synology's webui from the Windows 11 pc?)



2. Try creating a new user account on the Synology NAS and use those credentials to access the shared folders.



3. Check the firewall settings on the Windows 11 PC and ensure that it is not blocking the connection to the Synology NAS.



4. Make sure the shares are not SMB1 only, this protocol has been disabled by default in Windows 11

 

File Transfer Speed from Windows 11 to Synology NAS is VERY SLOW vs. Windows 10

I have a new Windows 11 PC and I'm noticing that the file sharing to my Synology NAS is very slow vs when I transferred files from my older Windows 10 PC.

File Transfer Speeds:

• Windows 11 to NAS (DS1520+) = 11.5 MB/s
  
• Windows 11 to Windows 10 = 112 MB/s (much faster)
  
• File size = 30GB
  

Note:

• Windows PCs and NAS are all Ethernet connected on 1GB home network.
  
• Running: Windows 11 Pro 23H2
  
• Running: DSM 7.2.1-69057 Update 5
  

Any suggestions on how to speed this up would be greatly appreciated. Thanks.
