Wired Ethernet vs Wi-Fi 7 mesh — what's actually better?

Wired wins every objective metric. The only question is whether you can run cable. After 22 years installing networks in homes, here's how I think about it.

For each TV in the house — what's the right call?

Main TV / home theater — ALWAYS Ethernet

This is the TV that has to work. 4K HDR, 4K Dolby Vision, surround sound — all need consistent bandwidth. Wired Ethernet is the only way to guarantee it. Cat6 cable handles 10 Gbps so you're future-proof for 15+ years.

Living room or den TV — Ethernet if you can

If the room is on the same floor as the router, or you have a basement to run cable through, wire it. If it's an upstairs bedroom and you'd have to fish cable through three walls, Wi-Fi 6E or 7 is fine.

Bedroom TVs — Wi-Fi is usually fine

You're typically watching one TV at a time in a bedroom, lower expectations on quality, and you don't want to tear up walls. Wi-Fi works.

Streaming sticks on portable TVs — Wi-Fi by definition

Roku Stick / Fire TV Stick / Apple TV mounted to a wall-mounted TV — running Ethernet to it is awkward. Some sticks have USB-Ethernet adapters if you want the wired path anyway.

How to run Ethernet without tearing up walls

  1. Use the attic: Drop cable down inside walls from above — usually 30 min per drop
  2. Use the basement: Run along basement ceiling, drill up into the floor of the room above
  3. Use a closet: If two rooms share a wall with a closet, run cable through the closet
  4. Use raceway: Surface-mount channel painted to match the wall — looks fine, no drywall work
  5. Use MoCA over coax: If your house is already wired for cable TV, MoCA 2.5 adapters turn coax into 2.5 Gbps Ethernet ($60/pair)
  6. Use Powerline as last resort: Plug into electrical outlets, get 500-1,000 Mbps. Works some of the time. Avoid if other options exist.
Spending $1,500 on a Wi-Fi 7 mesh? Spend $200 of that on Ethernet drops to your main TVs first. The wired connection delivers more value than the wireless upgrade.

Questions people actually ask

Real questions from real readers — and direct answers from 22 years of install experience.

Wired Ethernet to each TV vs Wi-Fi 7 mesh — what's actually better?

Wired Ethernet wins on every metric: lower latency (1-2ms vs 5-15ms on Wi-Fi), consistent throughput, no interference, no congestion. The only reason not to wire is if you can't run the cable. For a home theater or main TV, ALWAYS use Ethernet — Cat6 is plenty for 10 Gbps. Wi-Fi is for laptops, phones, and tablets that move around. If you're spending $1,500+ on a Wi-Fi 7 mesh, spend $200 of that on Ethernet drops to your TVs first.
