Compactly connect Cable Modem to 8-port POE Switch with DHCP

I use a Cisco RV320/325 router for this. Netgear make cheaper routers that are decent. A Cisco RV134 AC wireless router does DHCP, Wi-Fi and has LAN ports that you can use to connect your switch.

Most decent Wi-Fi routers have LAN ports.

That is exactly what I have been looking at.  However, everything I read say it is extreamely complicated to set up.  I can handle the dhcp setting.  But I need plug play similar to what you get with a Best Buy Linksys router.  I can disable wifi, but problem is Linksys router doesn't do POE.  How plug and play is the Edge X?  Except for email Ubiquiti has no support.  What do you know about this device?

I'm trying to configure a new smart home. Plan to sell next two weeks. I don't want to make the install too complicated especially if non-computer literate person buys the house and the power goes off.  I could use Linksys and forego POE, but I want owner to be able to easily plug in cameras without calling in a service tech.

Consider a small Wi-Fi router as I suggested above because they are easy to set up and use.

This was my original choice but avoided it because of lack of phone support.  After further searching this is as small as i have found.  We will soon see how easy the setup is.

David Johnson, I purchased edge x as you advised.  But am not smart enough to set this up. Presently, I connected to service provider via Cisco DPQ3212 Cable modem. This device has a single WAN/LAN jack.  It can sense it it is plugged directly into PC or router internet port which is presently a Linksys WRT540S with one internet port and 4 LAN ports.  One of those LAN ports is plugged into my Netgear 8-port POE Switch.  This works fine but doesn't fit in wiring enclosure.  I want to replace WRT router with new 4-port Edge X, but this device does not have an internet input port.  I presume I need to configure one of Edge ports for input from the modem.  The number one port of the Edge router is labeled POE input and the number five port is labeled POE Pass Through. The later is immaterial, however I am hoping I can not only plug the switch into port one of the router put this will also provide POE to the router and eliminate the need for separate power supply to router.  I would then like to connect modem to port two of the router.  I don't know if this is possible, but for sure the modem is not communicating with router.  I need.some help with this.  Alternatively, I would consider replacing the Edge and Switch with a single 8-port router and give up POE.  I can use an injector to supply power to upstairs access point.  This might simply things for end user down the road (the current setup with WRT is completely plug and play).  Would consider live support but this is new to me.

This problem is the reason I was avoiding Edge router from Ubiquiti; no support.  Can u help me?

did your run the setup wizard

I past this, and things are workin but I am concerned about  security, NAT, etc.   would you be available next week to do a live connection and go through the configuration with me?

I cannot seem to find the full manual to the edge router I have  which is a ER-X with version 1.7 OS.

have you gone through the manual?

I am thinking about the NETGEAR N900 Wireless Dual Band Gigabit Router, giving up on Poe, and connecting Ceiling AP with a power injector to  simplify things for the home buyer. I don't want to have to provide technical support.  It needs to be plug and play.  If anything goes wrong and things don't work they can call me and I will tell them to go to Amazon.com and just buy another router.   I have done a few smart homes and structured wiring installations, and after I leave the owners kids tear them up.   Nonetheless, I would still like to schedule some time with you to learn something about this this ER-X  I bought. The gigabit switch is easy and includes POE and doesn't require any configuration.  The ER-X worries me. I don't want to get any phone calls from the homebuyer telling me their Internet isn't working.
