Hamachi slow down internet - Do I need to keep putting the fix in place?

Hi,

 

I tried out Hamachi and noticed it slows down my internet, even when not connected.

I found the fix, for this which sorted out my download speeds, but would like to know:

 

Is it a 1 time fix or do I need to keep doing it?

 

Thanks

Re: Slow internet access when using hamachi as VPN

The solution works great and my download speed is back to normal, BUT I still have the same problem with my UPLOAD SPEED. Any news about how to fix UPLOAD SPEED too?

Slow transfer speed between two offices

Hello,

 

I have two offices at different locations and I use Hamachi to share network between them. Both of this offices have pretty good internet connection 100/100 FTTH. Unfortunately transfer speeds using Windows explorer are not more than 900 Kb/s. Connection is green - "direct tunnel".

 

What could we do about that?

 

Thank you!

After installing the program, the download speed in any browser becomes very slow.

Removing the program and restarting does not help. But when I wrote thats in the command line, this all became normal. The speed is returned to the original 9-10 MB.  

 

netsh int tcp set global autotuninglevel = normal 

netsh int tcp set global rss = enabled 

 

I didn't notice this before. Please fix

Very slow upload speed after installing Hamachi

 
Hello
I installed Hamachi on both of my PCs ( both Win10).
Unfortunately I now have the problem that my upload speed is very slow.
Normally I have 50mbit upload but after installation I only have 3-5mbit upload.
The effect happened right after installation.
Nothing else was changed in the system.

What can I do ???

Re: Slow downloads after installing Hamachi

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

 

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

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
