Windows 10: Windows 11 Refusing Connection to NAS

I have a Western Digital My Cloud EX2 Ultra that has been working without any trouble.I have an ASUS E410M that I recently did a clean reinstall of Windows 11, Version 26100.2605, Build 1000.26100.36.0.The NAS shows up under "Computer" and "Storage" in the Network folder of File Explorer.

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.
