Slow internet speeds after installing Hamachi

I've been having this issue for so long now! For some reason, my internet is blazing fast until I install Hamachi. Certain website downloads are affected but others aren't. for instance, downloading ...

    Try this to check the status of Receive Window Auto-Tuning Level

    netsh interface tcp show global

    and if it is disabled, turn it on with

    netsh interface tcp set global autotuninglevel=normal

    This helped me and two mates. The settings need to be run with admin rights cmd  (and shift+ctrl when you run it).

    As far as we understand it you would most likely want Receive-Side Scaling State enabled as well.

    netsh interface tcp set global rss=enabled

    We have not tested Hamachi after changing these settings. Nevertheless, just wanted to share because this problem was making us crazy.

Yeah Unfortunately, the only way to do this was to reinstall the OS. I'm very tired of this
I tried everything I know It all failed 
I'm tired of fighting this problem anymore.
The mega support team Say:We do not know how Hamachi works, so we cannot advise you, so could not help.
The only solution to this problem seems to be the Hamachi Support Team. It looks difficult too
I've been struggling with this for months. I have already written about this, but there is no answer

Then I saw your writing I feel as you say This problem won't be solved right away.
The RADMIN VPN you recommended works well without any problems Thanks for the recommendation
I feel like there's a registry involved... but I'm tired of trying it out :smileysad:
What's the matter now? I'm not going to use it. Thank you for your reply and have a nice day

      You need to open CMD (Command Prompt) as admin and put the commands below:

    You are my Hero, finally i found the issue after i already reinstalled windows! 
    But my Upload is still broken, should be on 50 Mbps and its on 10Mbps - any solving on this?


    We need to bring this information to Hamachi, it caused on both of my installations this issue! 

    THANKS!

      Glad our technical investigations were of help to others 🙂

       

      I think Hamachi are aware. One of my mates also posted the problem/solution on the forums, and if I remember correctly, he got an answer from one of the Hamachi employees stating they would fix it in some upcoming release. I believe, this was a few weeks ago (and pretty long after we posted).

    Just wanted to say thanks, this actually worked. I've had this issue before and reinstalling windows was the only thing that fixed it, but this seems to have solved it for me.
