I just bought a ET12 pack, to upgrade my ASUS RT-AX88U. I have set it up with the app (also tried via my desktop). It was all ok, but at the end the light goes red, no internet. I have set it up as wireless router (default), automatic IP. I have exactly the same settings in my AX88U, and it works. But it doesnt in the ET12. I have unplugged the WAN cable from the AX88U's WAN port, and connected it to the ET12 WAN port. My Virgin Superhub is in modem mode. I have no static IP, or anything special. In the AX88U, all WAN settings are default
