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.

SSH connection fails on Windows 11 "windows authentication failed. error 1326"

I have installed SSHD on Windows 11 and configured the SSHD as listed below following this blog:

1. Enabled Firewall rule to accept SSH connection
   
2. Added following lines to sshd_config
   

1. When I tried to establish a ssh connection either from my Windows local system or from a remote Linux system, I am getting an error "windows authentication failed. error 1326 windows 11".
   
   

The sshd.log file is uploaded here.

How can I resolve this issue?
