Re: cant change wan mtu on technicolor router

Have you checked with:
ip iflist
The MTU may have changed despite the error.

Re: cant change wan mtu on technicolor router

The following works for me, get the error but the mtu still changes.
ip ifconfig intf=Internet mtu=Huh?
saveall
Alternatively you could try:
ppp ifdetach intf=Internet
ppp ifconfig intf=Internet mru=Huh?
ppp ifattach intf=Internet
saveall
If you use this second one, I would make sure the setting is the same in the ip section.
