Hi - need some assistance with networking a Netgear Nighthawk R7000 and R4500 with Comcast Xfinity Bridged Gateway.

Scenario:
Three story house, 4000 SQ/FT.
Xfinity Broadband Gateway located in basement and is Bridged, no routing, no wireless.

Basement has centralized structured wiring, delivering Wired Cat 5 Ethernet to most rooms in house.

Xfinity Gateway connected via Ethernet Port 1 to Gigabit Switch in basement (DD WRT, switch only, no routing/wireless).

Netgear R7000 currently setup as Primary Router & WAP on 2nd floor of house, connected via wired Ethernet to Gigabit Switch located in basement.

Goal, connect R4500 (not WND4500) via wired Ethernet ***through basement Gigabit Switch*** as WAP on 3rd floor on same 192.168.x.x network.

Is this even possible? Again to review my topology:

Basement: Xfinity Bridged Gateway --Wired Ethernet---> Gigabit Switch-->
2nd Floor --Wired Ethernet--> R7000 Router
3rd Floor --Wired Ethernet--> R4500 AP

I believe I have a single IP being delivered by Xfinity Bridged Gateway to R7000.

R4500 currently states "no network connection" in GUI when connected via wired Ethernet to basement Gig switch.

If this is possible, settings for R4500 please?

How is the wiring to the other floors done? You can probably easily use one of those runs and just connect it to the router instead of the switch. It may help if you can diagram how everything is wired. Is there a punch panel in the basement going to the switch? You can just setup the lower end router in the basement, wire the switch to that off a LAN port, then use the second router off that as a WiFi extender with an Ethernet cable. You can even set them up to use different bands so the basement router can run on 2.4ghz that has a longer range, and the higher router can run on the 5ghz band for better speed and less interference.

So will be Xfinity Gateway --> R4500 ---> Switch ---> port in house ---> R7500 setup as a wireless...

Does the R7000 show the proper IP from the ISP in the WAN port settings if you connect to that? Is the R4500 connected to the R7000 using one of the LAN ports (not the WAN port) and is the DHCP on the R4500 turned off one turned off? With how you have things setup, you can't have both routers connected to the switch, since the Xfinity device will only give an IP to one of them.

Thanks - I thought that was the kryptonite. I can't cascade the R4500 off the R7000, rather, due to cabling in my house, must use switch in basement. If I put the R7000 in basement to Route traffic, I'm stuck with lousy Wifi.

crap.

Thanks for your response.
