At beginning it copies but then the transfer speed would quickly drop to (near) zero.
The file server is a Win 10 Pro. I have tested \\127.0.0.1 and \\[File Server IP] on that file server, both are fine.
But when other machines in LAN copy files from file server, transfer speed would quickly drop to zero. The problem shouldn't be on the switch as starting a HTTP server and downloading files is okay, and there is no sign of packet loss.
Ping result
299 packets transmitted, 299 received, 0% packet loss, time 298376ms
rtt min/avg/max/mdev = 0.545/0.916/3.943/0.359 ms
Network profiles should have been correctly set, I am expecting SMB access from OpenWrt and Port 2 (on an Intel I350-T4).
❯ Get-NetConnectionProfile

And this is my current SMB server configuration:

I was suspecting about SMB's signing and encrypting but they are not enabled. Besides, I have tried setting autotuninglevel to highlyrestricted but still not resolved. sfc /scannow and dism /online /cleanup-image /scanhealth are good. So what's next in order to figure out this SMB server's misbehavior?
