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 ...

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?

We have the nighthawk CAX30S, and then we have multiple "Eero Pro 6 Router"s in each of my brother's rooms as well as mine so that we can use ethernet cables to connect our computers to the internet. I have a friend who told me he uses "Modem Mode" on his router to make sure that him and his brother each have a different IPv4.

Instead of doing that do this:
Leave the CAX30 in router mode.
Connect the eero router to it and set them up including the satellites for it. After they're setup, go into their settings and put the eero in bridge mode.
It'll still act as an access point but it'll leave the CAX30 managing dhcp and therefor your IP addresses.
Just make sure to have the CAX30's wireless channels on different channels from the eero. And I'd use different ssid's for the 2 networks.
