MTU question

[link to this post]

My LAN MTU was set to 1504. My router MTU was set to 1500. If I run the ping xxx -f -l xxxx command I get errors until I reach 1452. I have now set both the LAN and router MTU to 1480. Is this correct?

I didn't know anything about MTU until about 30 minutes ago, sorry if this question is facile.

If sites that use HTTPS work, and other sites are fine and downloads seem a decent speed with no other issues then all is probably good.

You learnt quickly to have discovered the ping method and the adding of +28 smile

BTW: MTUs don't exceed 1500. What do you mean by LAN MTU. The setting in the PC?

If I were to run "netsh interface ipv4 show subinterfaces" via cmd then it would show my Local Area Connections. They both defaulted to an MTU of 1504. But I guess it doesn't matter if it says it's 1504, it will just cap at 1500.
