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.

omg
It's exactly the same problem as me
I've been struggling for months now and I'm sad that there's still no solution.
As you said, only OS reinstall is the solution :(

Oh yeah it's a REAL BUMMER having to reinstall your entire OS over a single app, but it was the only thing that worked for me. I have no clue why Hamachi slows your speeds like it does, but it somehow needs a clean install of the OS to reverse? Bummer for sure.

    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
