Upload speed capped below 100Mbps


Go to solution Solved by RobC1972,

Recommended Posts

I have AT&T fiber 1Gbps service. One of the latest updates severely limited by upload speed. Without MalwareByes running I top out at 950Mbps. When it is running it barely hits 60Mbps, sometimes close to 100mbps but never more than that.

Running the latest update of Premium 4.5.5

I went through the settings and I cannot find the source of this.

I ran windows updates and restarted. Same issue.

I decided to disconnect Ethernet and use wireless and the upload speeds go up to what I would expect them to be on wireless. I tested a USB-C network adapter and upload performance goes up to 950Mbps.

So it appears to be some kind of conflict with the Onboard NIC on this laptop. The NIC is a Realtek Killer E3100G 2.5 Ethernet. Probably a driver issue but whatever the issue is Malwarebytes and the Onboard NIC do not seem to get along.

I updated to the latest Killer drivers 10.53.1001 dated October 2021 and that did not seem to fix it. So right now I am using a USB ethernet until I can figure this out.

This was working fine before I was getting a flurry of updates to Malware bytes. The latest version seems to have introduced the issue.

Hello @RobC1972

Please check and see if there are updates for your BIOS. DO NOT, I repeat  DO NOT update your BIOS due to this issue, but I would recommend updating your BIOS or at least looking at updating it for your own security or features updates.

Check with MSI and see if they do have an update. The reason I say don't update for this issue is that a BIOS update can sometimes be tricky or sometimes something happens and it can break the computer. I've never had it happen but that doesn't mean it cannot happen. Vendors make it pretty safe to run an update as they don't want an RMA either.

 

 

Please download HWiNFO the Professional System Information and Diagnostics program.
HWiNFO Portable for Windows

Unzip the program to its own folder such as: C:\HWiNFO
Go to the new folder and locate the file C:\HWiNFO\HWiNFO64.exe and double-click to run it.
Click the RUN button.
Ignore the update, click close.
Click on Save Report and choose HTML and click Next, then Finish
By default, it will create a new report named COMPUTER.HTM in the same folder as the program. C:\HWiNFO
Please zip that file and attach it to your next reply

Thank you

You already appear to be using the latest Killer Elite software for the system.

What does your link show as requested by @Firefox above?

what does it show in your network adapter properties when you are connected with the on board network card? For Example, does it show 100MB or 1GB

This is mine...

You could try enabling the BETA version in Malwarebytes to see if that makes any difference as well. I believe we're trying to have a new beta out this Thursday if possible.

For the record.

I discovered that the issue is with the Killer Ethernet 2.5Gbps  device. You need to install the Killer Intelligence center along with the performance suite installed. Then turn off the prioritization engine (Killer Intelligence center) and things work as expected.

For some reason I attributed this to Malwarebytes. Though I was pretty sure that when I discovered the issue and tested by disabling Malwarebytes that the upload speeds returned to normal.

I knew Killer was the issue just did not know the solution. Thanks for sharing.

I had a client that was fixed by just my first suggestion I offered for Killer.
