Just to add a bit of discussion on the modem vs. modem + router thing. I know it’s a pain to have to get two devices; cost is higher; also two things to worry about hooking up/configuring.

At my previous place I bought a Motorola modem in 2012 or so. I kept that modem for 10 years and it chugged along delivering the speeds I paid for. Because it simply had an Ethernet port on the back of it, it meant that I went through 3 or 4 routers in that period. Some were replaced because I got a router for free from a friend and wanted to install custom firmware. Some were swapped in because the previous one failed, and the last one was added because I upgraded to a Ubiquiti Edge Router and two separate WAPs.

None of this would have been possible with a combo device.

Again, I’m not trying to convince you or anyone else that this is a path for everyone, just adding a different way of viewing the two devices situation. It offers you flexibility and plug-ability.
