Hi Iam_TJ. I have 'applied as default gateway'. Still no joy, even after a reboot! Thank you though.
I am going on hols for three weeks as of tomorrow, and will get back into this on my return.
Other than this one hiccup with IPv6, this VMG8924-B10A is proving to be a sterling modem/router with (so far) excellent stability (touch wood
) and (in my opinion) superb wi-fi.
It way outstrips the BT HH5A, Fritz!Box (as modem/router) and even the HG612 with the Fritz!Box as router only, all of which I have used in the past.
Edit: Typo.
