Igen. Mindenféle korlátozást kipróbáltam.
De évekig működött minden auto beállításokkal, nulla buherálással. Ebből gondolom, hogy teljesen más gond lesz itt.
lehet, hogy MTU probléma lesz. kipróbálnám az alábbiakat:
OK. The thing is in MTU ( maximum transmission unit ) you have to change default value from 1500 to find an optimal transmissions amount. It's easy to do so lets start.
Open CMD by clicking start icon Command Prompt(Admin) and paste this command:
ping
www.google.com -f -l 1500
If you will see the message like: Packets need to be fragmented but DF set, drop the test packet size down (10 or 12 bytes) and test again, to 1490 - 1480 - ... Drop the test packet size down more and test again until your reach a packet size that does not fragment.
Once you have a test packet that is not fragmented increase your packet size in small increments (1-2 bytes) and retest until you find the largest possible packet that doesn´t fragment. Take the maximum packet size from the ping test and add 28. You add 28 bytes because 20 bytes are reserved for the IP header and 8 bytes must be allocated for the ICMP Echo Request header.
In my case the latest stable one was 1454 + 28 = 1482 < This is my optimal and workable MTU packets.
After you found your optimal packet sizes, you need to apply settings to your ( VPN / LAN connection ).
Open CMD as Admin and type:
netsh interface ipv4 set subinterface "Your LAN NAME GOES HERE" mtu=PASTE HERE Optimal value store=persistent
and press on Enter. Repeat with IPV6 the same command:
netsh interface ipv4 set subinterface "YOUR LAN NAME GOES HERE" mtu=PASTE HERE Optimal value store=persistent
Repeat all these operations with all network adapters that you have. If you are using PIA it should be called Ethernet2 and Ethernet re-check names in "Open network and sharing center" so these commands will sound something like this :
netsh interface ipv4 set subinterface "Ethernet 2" mtu=1480 store=persistent
netsh interface ipv6 set subinterface "Ethernet 2" mtu=1480 store=persistent
netsh interface ipv4 set subinterface "Ethernet" mtu=1480 store=persistent
netsh interface ipv6 set subinterface "Ethernet" mtu=1480 store=persistent
Don't forget to press on Enter after pasting each command to CMD
After these will be done, re-check if they set correctly by opening command prompt(CMD)as admin again
and post this:
netsh interface ipv4 show subinterfaces
netsh interface ipv6 show subinterfaces
You should see your values ( that you will set manually by choosing optimal transmission units above )
