adding the XB8 to my home network

My present system uses an Arris S33 modem which is connected to an Asus RT-AX88u router.  Six ethernet cables are connected to the Asus RT -AX88u router.  In a separate location in my home I used one of the ethernet cables from the Asus RT-AX88u to connect to an Asus RT-AC58u, which is used as an Access point.  I just receives an Xfinity XB8 modem/router. My question is, how do I make the proper connections if:  1I wish to use the Asus RT-AX88u as an access point, using the wifi on the XB8 in the part of my home where the Arris modem presently is?  2- I would move the Asus RT-AX88u to replace the RT-AC58u access point?3- the XB8 has 4 ethernet outlets, one with a fast speed.  I need 6 connections.  Should I run an ethernet cable from the fast connection on the XB8 to either a switch or hub? Therefore I have the 6 connections I need?Thank you in advance

As long as I’m getting the ideas here right:

1. it would involve ensuring that the AX88u is set to Access Point Mode so that the XB8 is used for routing.

2. it would basically be a matter of unplugging the old access point and plugging the AX88u in its place.

3. you can use a switch for that. For the fast 2.5 Gbps port, I would try to leave that open unless you have a device that has a 2.5 Gbps supported port to take full advantage of it, especially if your speed tier is either Gigabit or faster.

@user_6eaedb Good afternoon! Thank you for reaching out to our Community Forums Team for assistance with your equipment and services. I can see you have quite the set up there, and want to be sure you are able to get your services and equipment set up in a way that works for your household. To be honest, our modems are not really designed to function in this manner, and this could be tricky in getting this to work the way you are intending. Usually in this instance we would recommend our xFi pods for the access points. I'm including some information for you on the xFi pods. Please let me know if you have any follow up questions I may answer for you!
