Fix internet speed after installing/using hamachi

[CORKY 1843]

Hello metin2dev!

You might've noticed that after using hamachi (if you still do, i recommend moving to localhost directly, since it's a outdated method anyway to use hamachi)
that your internet speed went considerably down like it was being limited.
The problem is from hamachi limiting the system while using their free version.

You can fix this problem easily from cmd.

First let's check the changed values AND if they're even modified.

Open cmd with administrator and run the following command:

netsh interface tcp show global

 

If "Receive Window Auto-Tuning Level" is disabled, you need to enable it again. In order to do that, run the next command into the command line:

 

netsh interface tcp set global autotuninglevel=normal

 

Now, an optional step, you might want to enable "Receive-Side Scaling State" as well, hamachi might've changed this value too. We'll do it with the following command:

netsh interface tcp set global rss=enabled

 

 

After doing these steps you can do a speedtest and should see the differences before & after using hamachi.

I hope no one uses hamachi anymore xD

Who will use hamachi in 2022? Now you can start a server from 2007 ex: rain serverfiles in 3 minutes, not more than when you needed some skill to install a server in 2007

Thanks for the contribution, but I don't think it makes sense to have hamachi stuff, it's outdated

Guide/Release contents are less than ever.

I think we should tell people more encouraging things instead of "we don't need this, it's useless" etc.

Thanks for topic.

Thank you! I'm still using Hamachi because I have 2 servers running simultaneously on my machine..  I didn't event think Hamachi was the cause of my slow internet speed.

I dont use hamachi, but i use RadminVPN, its like a better version of Hamachi, and yes, both hamachi and radmin and other type of programs like this are still in use in 2022, just because the majority of people dont use them, doesn't mean they are useless, for example, i use it for creating multiple servers, not only metin, and paying for a vps/host for each individual server would be impossible, and port forwarding isn't an option since my ISP doesn't allow it,  and this way, my ip is also more hidden
