HI. I have the EE Smart hub SH31B. Lookin into the Broadband advanced settings, I am unable to locate any MTU setting. Is such available? If so any guidance is most welcome.

Best wishes

It's hardcoded to 1492 as being the recommended MTU for a WAN interface connected to a PPPoE network.

G'day

Yes, an MTU around 1492 would be common. On my W11/Edge.com I have to set MTU at 1464 to achieve 0% loss on 4 packets sent, although adding 28 is recommended.

You'll generally get 0% loss anyway. It's only when it's too big that you get fragmentation.
