How Can I Troubleshoot SMB Settings - Slow Transfers On Network

Hey!

I am having problems with my SMB transfers. I couldn't figure out why it went from 100 mb/s down to 10 mb/s one day. I ended up creating a new user (admin) and that seemed to fix the transfer speeds. However, after 2 weeks, I'm back down to 10 mb/s again. I didn't install anything new. I didn't make any changes, nothing change, at least by me. 2 days ago it was fine. Today I went to transfer a file and noticed it's at 10 mb/s once again.

How can I troubleshoot this? I'm completely lost and have no idea why this has happened again. It obviously has something to do with an update or something where the computer has changed the settings somehow.

I am using Windows 11 on both machines. One (my main desktop) is a built machine and the other is a Dell Optiplex 9010 which I solely use for my media server (Emby). Here are their specs:

Built Machine: (Transfer from)

12th Gen Intel(R) Core(TM) i3-12100F 3.30 GHz

32.0 GB (31.8 GB usable)

Windows 11 Pro (24H2)

Dell OptiPlex: (Transfer to)

Intel(R) Core(TM) i5-3570 CPU @ 3.40GHz 3.40 GHz

12.0 GB

Windows 11 Pro (23H2)

    Hello.

    Based on your understanding of the problem, I recommend that you open Powershell as an administrator and run the following command to ensure that the large Maximum Transmission Unit (MTU) is not disabled and that bandwidth limiting is not enabled in the SMB:

    Set-SmbClientConfiguration -EnableBandwidthThrottling 0 -EnableLargeMtu 1

    I suggest you refer to the following links:
