Ethernet or Wi-Fi for working from home
Use Ethernet for the desk you work at if a cable is practical. Leave Wi-Fi for phones and devices that move.
Cable the desk, not the phone
Video calls fail when Wi-Fi retries. A cable from the router to the dock or desktop avoids that hop. If you cannot run a cable, a powerline or MoCA adapter is a thing to research for your wiring, not a promise, and a well-placed mesh node is the alternative in mesh versus extender.
Who this is for
A home desk used for calls most weekdays.
Decide
- If the router is in the same room, use a short cable.
- If the router is elsewhere and the work is paid, a single careful cable along baseboards is often cheaper than a new mesh kit.
- Keep the cable out of the walkway. See call lag for the other causes.
Limits
Do not drill through fire-rated walls or run cable outdoors from this article. Renters should use surface routes they can undo.
Questions readers ask
Is Ethernet always faster?
It is usually steadier. The internet plan still caps the speed. A cable removes the room’s Wi-Fi from the path. It does not raise the plan.
