problem installing AX4 (RAX40). Cannot get to internet

Here is my setup before I touched it today. Comcast internet 300 MBS to Arris SB8200 Modem and then to R6300v2. Everything is great.   To "improve" things I did a straight swap of the R6300v2 wit...

    Same issue. After reading how many hours it took experts to figure it out, I'm sending the POS back and exchanging for a different brand. My old TPlink is working fine, just wanted something faster, not a headache. Thanks

While not as popular as the common 192.168.0.1/24 or 192.168.1.1/24, the 192.168.100.1/24 is a popular default LAN IP used by products from many vendors, including Ambit, Arris, Askey, Cisco, Motorola, Netgear, Scientific, USR, .... ZyXEL - typically cable modems, but also on other CPE like 3G/4G routers

The default for the RAX40 is 192.168.1.1

 

I checked the manual.

 

My question is how come the user wants to get at a different IP address?

 

Why do they want to address the modem?

 

I sense some confusion.

 

I am not interesting in devising complicated theories. I am interested in finding out what is going on. In that way it is easier to suggest possible solutions.

They do not want to talk intentionally to the modem - it just happens that while certain CPEs like cable modems are not provisioned yet - that these devices have a default LAN IP, an active DHCP server, and many times a captive portal so an attempt to connect the Internet does hit the cable modem, for indicating a problem situation locally, for the time the uplink and downlinks are not established yet.

 

This happens when users reboot the cable modems, and it can take even longer if they decide doing a factory reset of these units.

 

Nothing wrong, and a nice proof the router and it's Internet/WAN Interface is working as expected - up to the CPE.

 

Lack of any more insight (ISP, config requirements, ...) it's difficult to assist on why the RAX40 can't be used to establish the Internet connection.
