"Quote from: hushcoden on March 20, 2026, 05:10:01 PMI've got my new FTTP connection (PPPoE with no VLAN) and in the WAN interface I can see "Calculated PPP MTU: 1492" and I hope I can bring that value up to 1500.
Reading the first post, I should also set the MTU on my ONT, but I have no access to its GUI, so hopefully it won't be a problem.
The only thing I can do is clicking on the WAN interface -> point-to-point configuration - > Advanced -> Show advanced options -> MTU = 1508
Is that it?
Tia.
The ONT is usually from your ISP which doesnt allow a enduser to change things on it. So settings the WAN interface to 1508 should cover it. You can verify it with the 1472 ping (exact syntax is in this topic), if you get a reply all is ok.
