How to Choose an Ethernet + Coax Wall Plate for a Cable Modem or Router Setup

A cable modem or router setup looks cleaner when the wall connection is finished properly. Instead of loose coax and Ethernet cable coming out of the wall, an Ethernet + coax wall plate gives both connections a fixed location.

For homeowners, small offices, media rooms, and low-voltage projects, the right wall plate can make the setup easier to service and better looking.

Start with the connections you need

Most modem and router locations need coax for the incoming cable signal and Ethernet for the network connection. A wall plate with an F-type coax connector and an RJ45 Ethernet port puts both connections in one place.

This is useful behind desks, near network shelves, in media cabinets, next to routers, or anywhere a cable modem and Ethernet drop land together.

Choose RJ45 keystone jack or coupler

If the Ethernet cable in the wall is raw unterminated cable, choose a wall plate bundle with an RJ45 keystone jack. That gives you a proper punch-down termination at the wall.

If the cable already has an Ethernet plug on it, choose a coupler-style wall plate. A coupler works as a pass-through connection, so a finished Ethernet cable can plug into the back and another cable can plug into the front.

Choose Cat6 or Cat6A

Cat6 is a common choice for home and small office Ethernet drops. Cat6A is a stronger choice when you are planning for higher-performance networking, longer useful life, or 10Gbps-ready wiring.

For modem/router setups, either can work depending on the cable already in the wall and the network speed you want to support.

When shielded parts make sense

Shielded RJ45 parts are helpful when the cable run is near electrical interference or when the project is for a network room, office, commercial space, homelab rack, IP camera setup, or PoE device wiring.

If the install is basic residential wiring, an unshielded Cat6 or Cat6A option may be enough. If the install is more demanding, a shielded option is worth considering.

What to look for in a clean wall plate setup

• RJ45 Ethernet connection for the network drop
• F-type coax connector for cable modem or TV signal
• Cat6 or Cat6A rating that matches the project
• Shielded option when interference protection matters
• A finished wall plate that keeps cables organized

Recommended place to start

Browse the R.J. Enterprises Ethernet + coax wall plate collection to compare RJ45 keystone jack and coupler options.

For a simple cable modem or home router setup, start with a Cat6 or Cat6A RJ45 keystone jack + coax wall plate bundle. For pass-through installs, choose a coupler version. For more demanding office, PoE, or homelab wiring, look at the shielded Cat6A options.

If the project also includes rack-side wiring, the patch panel collection is the natural next stop.
