Ethernet vs WiFi
Wire when it counts.
When to use Ethernet
- Smart TV — streaming 4K is much smoother on cable.
- Desktop computer — wired is faster + steadier.
- Game console — kids' gaming benefits.
- Home office — Zoom calls don't glitch.
- Voice phone (VoIP) — sounds clearer.
- Anything that struggles on WiFi — try cable first.
When to use WiFi
- Phones, iPads, laptops (mobility).
- Smart home devices (Echo, smart bulbs).
- Anything you carry around.
- Most of your home is fine on WiFi.
No nearby ethernet outlet?
- Long ethernet cable — $10-30 for 50ft. Run along baseboards.
- Powerline adapters — TP-Link AV2000 ($60). Use HOUSE WIRING as ethernet.
- MoCA adapter — uses COAX (TV cable wires) as ethernet. Best for older homes.
- Hire electrician — runs CAT6 wire through walls. Permanent.
Cable choice
- Cat6 — supports gigabit. Most homes. $1/ft.
- Cat6a / Cat7 — for 10+ Gigabit. Overkill for most homes.
- Cat5e — older, still works for most home use.
- Don't buy fancy "audio" Cat cables — marketing. Cat6 is Cat6.
- Amazon Basics, Monoprice = cheap + good.
Best ROI: TV ethernet
Smart TV on ethernet = stable streaming. No buffering. No "sorry, video paused" interruptions during the game. $20 cable + 5 min run = best WiFi upgrade for many seniors.
