Kubuntu 24.04, 25.10, 26.04

KDE Plasma

Problem Description:
windows 11 smb share connection very slow

I have connected to a remote share”sg2” on a windows 11 machine from my kubuntu 24.04 machine using the following command:- sudo mount -t cifs -o username=xxxxx,password=yyyyy,gid=1000,uid=1000,rw //192.168.0.31/sg2 /mnt/sg2

This works in that I can read, write, copy files in the shared folder but the connection is very slow (<100 kbs). If I boot windows 11 on the same machine and connect to that share all works at full speed so I don’t think it is a physical network problem. What have I missed?

Many thanks in advance – Ian

Open PowerShell as Administrator then run

Get-SmbConnection

Then look for the Encrypted column. If it says True, encryption is active.

Then to disable SMB encryption (for testing) then run

Set-SmbClientConfiguration -RequireSecuritySignature $false

Then test your file transfer speed again.

Hi Pavlos. Thanks for the swift response. It took me a little while to get accessto the Win11 machine. On the machine I am working with will not accept capital letters on the command line and the command get-smbconnection is not recognised (PowerShell 5.1). Any ideas?

Maybe win11 needs updates, I’m not a Windows person – I use Linux – but the issue is the Win11 adds encryption by default so the code above temp disables it. Run tests to see if your speed is better. I don’t have this issue since all my servers are Linux. Maybe a win person can explain why PS does not accept upper chars.
