@skua123,

Lot to unpack here:

First, What TV Provider do you use? If you have Verizon's new Streaming Box Setup, your Verizon Router will be required to communicate with the TV boxes. Otherwise, it is most likely that the router from Verizon will not be necessary at all. 

The main thing is that you do not want to have more than one main router on a single network(besides mesh satellite nodes). This can cause a variety of issues and is the reason why routers, including your Deco, can be placed into Access Point Mode.

If you do not want to remove the Verizon router from your network configuration, you can switch your Deco X60's operation mode to Acess Point Mode after initial setup.

TP-Link works with security companies across the globe to keep our devices secure for our users. This is done through either the HomeCare or HomeShield settings on your router. Unfortunately, these settings are only available when the TP-Link router is managing the network traffic and is set up as the main router on the network.

  @skua123,

You are defintely able to take the Verizon Router out of your network setup, so as to receive a better overall experience. Only thing, depending on the type of cable that is running from your ONT to your router, there may be additional steps:

If it is an Ethernet Cable, the system will be very easy to substitute. If there is a coax cable, there will have to be some communication with Verizon. Apparently, most ONTs have an Ethernet Port on them, however they are often disabled  by the technician in favor of coax cabling. You will have to get in contact with Verizon to reenable the port, then you can proceed with connecting via Ethernet to your TP-Link router
