Nobody know?
I need to change it to 1472 instead of the default 1500.

Re: How to change MTU?
While I don't know if Sky Fibre changes the GUI of the 7800N as to normal - not being a Sky user, you could try changing it in the computer (IPv4) to see if that helps.
Open a cmd prompt as an administrator then enter the following cmd -
netsh interface ipv4 show interfaces (press Enter)
This will show the sub interfaces for the Pseudo Loop, Wireless and LAN.
Using the Index number in the left column - say it's 12 for the Wireless and 15 for LAN, enter the following cmd for that interface to your required MTU.
netsh interface ipv4 set subinterface 12 mtu=1472 store=persistent
Then repeat the cmd for the LAN with its Index number - ideally it should be set in the router as well but in the absence of any definitive help on the forum then you could open a ticket at http://www.billion.uk.com/esupport if just setting it in the computer doesn't resolve.
Repeat the ...show interfaces cmd to confirm that the changes have been made.

Re: How to change MTU?
Could someone from Billion support please confirm that the mtu is not adjustable or can even be viewed within the sky fibre (UK) firmware in my 7800N router?
I have adjusted the mtu on my PC.

Re: How to change MTU?
I do NOT have the mtu option that is in between Obtain DNS & Vlan Mux in my firmware.
My firmware is v1.06g.dc1.
I assume the image posted is from another firmware???

Re: How to change MTU?
Thanks. I did not know there was a newer firmware for the 7800N and sky fibre.
I will try later when I have more time.
