Hi, new user here. I hope I haven't made an error but I've just posted a new message on the Asuswrt-Merlin forum (thread title -Support for 4G-ac68U) and only now realise that perhaps I should have posted the link to Asus firmware here - though the info I posted seems relevant as the original thread concerned flashing the router with a different router's firmware. Anyway, apologies if I have made a mistake.
Best,
V
