Hello, if you suffer from frequent disconnect or desynchs you may want to try this guide.

You need admin rights of your computer, half a brain and the password to your router (it is likely “admin” as username and password anyway)

First of all open your command prompt, click start or the windows symbol bottom left for win10 users, enter “cmd” and rightclick on the CMD-symbol, then “run as administrator”.

When you have the lovely black window open enter
ping api.playerio.com -f -l 1472
you can just copy+paste it from here. You will now see how your computers sends 4 files and receives 4 files, it may lose a few of them. If it says “4 sent, 4 received, 0 lost” you are fine and you can now be sad, because I cannot help you with your connection problem, the cause is somewhere else. If you lose a package however you can change your MTU value and improve your connection.

Enter the same command as above but with a lower number:
ping api.playerio.com -f -l 1470
enter this with lower and lower numbers until nothing is lost anymore. Write that number down, lets say it is for example 1468.

Now we need to find out the index of your ethernet, we do this by entering
netsh interface ipv4 show interfaces
and your get a very small list, one item should be “ethernet” and under “idx” some small number which you have to remember.

Final step, enter:
netsh interface ipv4 set subinterface 5 mtu=1468 store=persistent
where YOU have to change the number behind the MTU= ↑ and the number behind “subinterface” is the index of your ethernet.

So if your MTU has to be set to 1444 to lose no packages and your ethernet index is 10 the command would be
netsh interface ipv4 set subinterface 10 mtu=1444 store=persistent

When you are done the desyncs should stop.
