Nighthawk CAX30S- How do I turn on Modem Mode?
I'm waiting for my older brother (he has the app) to wake up so that he can do this, as I'm unable to login to routerlogin.net both on my computer and phone.
My understanding is the following: we unplug all of the routers in the house other than the nighthawk > set up modem mode in the nighthawk app (hoping this is as simple as turning a setting from OFF to ON, if not please let me know what else has to be done). > turn off nighthawk router, turn on, wait 2 minutes > turn on other routers, then after 2 minutes or however long, all of the routers will have different IP addresses as modem mode is on.
Please let me know if there is anything else we have to do. I'll update in a few hours when my brother is awake.
Just spoke to a technician from my ISP who spoke to his supervisor who said "the ISP doesn't give out the power to change IPs to people under residential plans" or something along the lines of that. I think the only thing we can do is change ISP. I'm gonna update the post with this information.
EDIT: Can't edit the original post, in summary for anyone experiencing the same / similar problem as me; Mediacom (my ISP) technician and his supervisor were unable to change my IP, said we would have to pay hundreds of dollars more per month for a business plan just for that privilege. I've heard of people in the US having dynamic IPs that change public IPv4 every time the router is reset, so I have no idea why Mediacom would take such a stance on this issue. I think the last resort is to call them and let them know we'll have to change ISP if they can't resolve this issue for us.

Hey thanks for the response, I followed these steps but upon turning router mode off and then turning the nighthawk off and on, the nighthawk turns on but none of the other routers have working internet. Any idea what to do?
when you say "routers" it sounds like you have more than 1 connected.
Most ISP's only support 1 public IP address. Meaning only 1 device can be connected if its acting as a modem only device.
do you have more than 1 connected?
Is there a reason you're wanting to use it as a modem only device?
Its a solid router and you could leave it in router and connect the 2nd router to it in access point mode
Hey, I am doing this because I need all of the routers that connect to the nighthawk to have different IPs from each other. Even with router mode on, everyone in the house other than my brother who connects to the nighthawk via ethernet use these routers for their ethernet: Eero Pro 6 Router (would post the amazon link but not sure if it would get flagged).
EDIT: What is access point mode? Would that make sure I have a separate IPv4 from my brothers?
