Help Needed Setting up by Home Network

[GreyKnight2208]

Hey Y'all,

 

I have a Gateway/Cable box (we'll call this box Arris) which my ISP provided me (have to use this), this also serves as a WiFi Router for the downstairs of my house, but I need coverage upstairs too, for this I have a separate router (we'll call this box Linksys). I connected Linksys to Arris via ethernet cable and did a basic setup which provides upstairs with the Internet, but this puts my house on 2 different networks, meaning none of my devices upstairs can stream to my Downstairs TV's and none of my upstairs PC's can connect with PC's downstairs over LAN. How do I get Linksys and Arris to work together under one network?
 

My Downstairs Router is the Arris TG862.

My Upstairs Router is the Cisco Linksys EA4500. (I do also have a Cisco Linksys X3000 buried away somewhere that i could probably use if needed.)

 

Thankyou for your time.

The problem is that you are running a double NAT setup.

What you want to do is disable NAT or any router functionality on the linksys, so that it runs in a switch/AP mode.

bridge the linksys to the arris 

and they will be on one network

Configure Linksys as access point. Disable DHCP.

bridge the linksys to the arris

In this context, bridging isn't really the correct term.
