How do I set up my home network?
I just moved to a new home that is large enough to need 2 WiFi access points. Unfortunately I'm a total noob and I'm having problems.
Old setup: Cable modem (Arris Surfboard) > TP Link WiFi router > various Ethernet ports around the house
New setup (attempt 1): Surfboard > PoE switch > Unifi AC Lite + upstairs Ethernet > second PoE switch > second AC Lite
Some searching revealed that my modem was not acting like a router and thus nothing was assigned an IP address. I could still get online with my upstairs PC since it was essentially wired directly into the modem via switches and cables. But my Unifis couldn't be adopted even though I could see them through the software.
So I decide to use my old WiFi router as a regular router. I disabled the wifi on it and connected it between the Surfboard and the first switch. Now I have no internet and also no wifi.
What do I need to do to get it working? I have only the equipment mentioned in this post - 2 switches, 2 AC Lites, a traditional WiFi router, and a cable modem. Help!
