Installing Hamachi slows my internet speed

Before installing Hamachi my internet speeds are showing 200Mb/s. After installing it I constantly get 60Mb/s. I have uninstalled Hamachi but nothing changes, is there a setting somewhere that can resolve this?

Re: Slow internet access when using hamachi as VPN

Hi everyone,

I apologize for the delays, and expect the next version to have native API calls instead of netsh background configurations.  Until that time (as mentioned previously), you can run the following commands to resolve:

netsh int tcp set global autotuninglevel=normal
+
netsh int tcp set global rss=enabled

Re: Installing Hamachi slows my internet speed

My system specs, I meant to put this in the original post.

 

Windows 10 latest patches

i7 4790k @ stock

16GB DDR3

1TB NVMe drive

 

My internet is 200Mb/s but after installing Hamachi it falls to 60Mb/s

Re: Installing Hamachi slows my internet speed

I just did a test on a Windows 10 VM and when I installed Hamachi the VM went from 200Mb/s to 60Mb/s could this be a setting somewhere or a bug?

Re: Installing Hamachi slows my internet speed

I had to do a system reset. Once I did that I updated everything and made a restore point before installing Hamachi. I then installed and it did it again, slowed my bandwidth down. I then restored back to before the installation and everything was back to normal. Since I have to use hamachi for work I have it running through a VM and just do all work related stuff through the VM. This is sad that no one from Logmein has responded to this...

Re: Installing Hamachi slows my internet speed

If you want to save some files You can only use Windows OS to initialize it.  Keep the file but delete only the settings and os app.  https://ckghwn.tistory.com/629 It's difficult because it's in Korean You can tell it roughly by explaining it with an image.  I initialized os and saved the file through this method
Kindly, you will have an html called Removed App on your desktop. It's easy to reinstall while looking at it
If you have a graphics card driver, use a DDU It is recommended to remove and reinstall
See the link https://community.logmein.com/t5/LogMeIn-Hamachi-Discussions/Slow-downloads-after-installing-Hamachi... for another alternative.

Re: Installing Hamachi slows my internet speed

That's weird. In my case, the steam origin had a normal down speed.
I've only experienced a slowdown in megacloud.
At this time, the only way to fix it is to restore the OS on Windows 10 itself.  Sad news
If you only need to delete games and settings apps  Try using a recovery method that only reinstalls os
It will not delete video files and portable file And it will tell you which apps you kindly deleted on your create htlml remove app desktop So just watch and reinstall the apps you deleted I think this is the only way I can tell you.

Re: Installing Hamachi slows my internet speed

Co-worker and I have the exact same story.  Installing Hamachi caps our speed at about 100mpbs.  Uninstalling it does not fix anything.  If we do a complete OS reset, it goes back to normal.  Install Hamachi again and it gets capped.

LogMeIn support provided no assistance and said it wasn't their software when clearly it is.

Re: Installing Hamachi slows my internet speed

I found a way to keep Hamachi and maintain your internet speed while you are not using it

 

Go to Services (Windows Search Bar: services.msc) and look up for LogMeIn Hamachi Tunneling Engine, disable it and restart the computer. It worked for me, if I need to use Hamachi again I'll enable it just for the time being. This way at least you won't have to format the OS.

 

Hope it helps! Is not the ultimate solution but it works.
