Just got an Archer AX3000 Gigabit Wi-Fi 6 router to replace a Linksys router which was working perfectly well, but had gone end-of-life with no more software updates.

I am installing this behind a Verizon Fios gateway, model G3100

Setup went easily enough except it cannot connect to the internet.

Looking for some troubleshooting tips.

One thing I would like to do is move the new TP-Link to a 10.10.x.x IP address space to eliminate any confusion. RIght now one router is at 192.168.1.1 and the other is at 192.168.0.1  Those are two separate networks or subnets but I'd rather not have to mess with netmasks and stuff.

Any constructive and supportive comments are welcome.
