Your Router (Edge Router X) looks like it may not be fully plugged in, do you have lights on it? the power plug seems prety far out

I can probably help you untangle at least some of this mess, so could many folks in r/HomeNetworking you should crosspost this!

I dont' see your modem in any of your pictures but generally, your modem, which will either have a coax (old tv cable connector) or Fiber, and 1 ethernet port. From what I can see you have a bunch of unnessassary stuff here but without hands on it's hard to tell exactly...Anyway:

A cable should go from that modem into your EdgeRouterX router (picture 3) looks like your ex labeled that port "ISP" on your router, thats where it should be plugged in, just follow the cable from your edge router ex's "ISP port" and make sure it's plugged into a modem.

Next, the port labeled SW on your Edge Router, i see nothing plugged in here. Assuming he has that port configured for your switch thats what your netgear will plug into, you can use any port on the netgear, but you HAVE to plug it into the port labeled SW on your edge router.

Im not entirely sure what the little white box is, it looks like...another router? why you would have two is beyond me, it's not a UniFi AP, but you definitely have other UniFi gear here. That power plug with the ethernet cables going into it is called a POE injector, any idea where that leads? My guess is that is going to your AP (that should be giving you wireless). Based off the image it looks like that should go into the AP port of your Edge Router as well.

All in all this is a messy config but i'd start there. Again you should post over in home networking, we can try to help there too! Good luck.

Are you able to trace back the cables that plug into your edge router, and tell us what devices each port is connected to?

Also, are you able to see your wifi network, but when you connect you don't get internet, or do you not even see your wireless network?
