Frequently Asked Questions

Something specific is in the way. Usually an interior brick or block wall, plaster over metal lath, foil-faced insulation, or a tiled bathroom backing onto the room. A large mirror or a wall-mounted television on the router side of that wall does it too. The two-minute test identifies which.

One or two bad rooms means an extender; three or more, or a whole floor, means a mesh system. Budget should not move that line, because three extenders cost more than one budget mesh three-pack and work worse — extenders do not chain, so each hop halves throughput again.

Start at one radio per floor you use, add one for each area cut off by masonry and one for any floor longer than about 50 feet, then cap the total at four. Most houses land on two or three. The full sizing method.

No. Range has not meaningfully improved across recent Wi-Fi generations, because transmit power is legally capped and your phone transmits back far more weakly than the router does. A dead zone needs a radio physically closer to it.

It is the link mesh nodes use to talk to each other. If it shares a band with your devices, the far node passes on roughly half of what it receives. If it has its own band, most of it. If it is a cable, all of it. That makes it the single largest determinant of whether a mesh system is good — and it is rarely advertised.

Yes if you live in a dense building, your plan is a gigabit or faster, or you are replacing hardware you will keep five years. No if your problem is a dead zone, or your plan is under a few hundred megabits. The longer answer.

That is congestion rather than coverage. Wi-Fi listens before transmitting and waits if it hears anything, so in a building full of networks everyone spends most of their time waiting. Adding radios makes it marginally worse; changing band or channel is the fix. How to do that.

Central, as high as practical, out in the open, and away from metal and water. In a two-floor house, an upstairs landing is often the single best spot. It is free and it is the largest improvement available to most households — the full rules.

Roughly halfway between the router and the bad room, never inside the dead zone. An extender can only rebroadcast what it receives, and in the dead zone it receives almost nothing. If there is an open doorway into the room, position it in the doorway's line of sight.

On almost every provider, yes, though the mechanics differ. On cable you buy an approved DOCSIS 3.1 modem or keep theirs and add your own router. On Verizon Fios you plug straight into the ONT. On AT&T Fiber the gateway stays but can be put in IP passthrough. On Starlink, use bypass mode. Per-provider detail.

Anywhere from nothing to about $25 a month, and published sources disagree. Guides list Verizon Fios, AT&T, Frontier and T-Mobile at $0, Spectrum between $0 and about $10, and Xfinity around $15, or about $25 for its mesh service. Read the equipment line on your own bill — that is the only figure that applies to you.

If you keep it and add your own router, yes. Otherwise you get double NAT — two routers each handing out private addresses — which breaks port forwarding and some games and VPNs while adding latency for nothing. Turn its Wi-Fi off as well.

MoCA turns the coaxial cable in your walls into a network connection. If two rooms both have a coax outlet left over from cable TV — which most US homes do — a pair of adapters gives you a shielded gigabit-class wired link with no new cabling. How it works.

In many houses very well, and in some badly. The dominant factor is whether both sockets sit on the same circuit breaker phase, then wiring age and appliance noise. Never plug one into a surge protector — it filters exactly the frequencies powerline uses. More.

Because a speed test measures how much data you can move over ten seconds, and a call needs data to arrive evenly. On a marginal link, failed packets get retransmitted fast enough to keep the average high but too late for a real-time stream. How to diagnose it.

Roughly 15 to 25 Mbps per simultaneous 4K stream, and up to about 40 on the highest-bitrate services. Most buffering happens on much faster connections, because the problem is the link to the television rather than the plan.

Separates, for most people. Modems and Wi-Fi standards age at different rates, so separates let you replace only the outdated half. More importantly, a combo must sit where the line enters the house — usually the worst place for a radio — while separates let the router move somewhere sensible.

No, and we say so on every page. We do not run a lab. Recommendations are built from published specifications, measurements taken by named independent outlets, and structural reasoning about what a house needs — all cited. Our methodology explains exactly what we do.

Because we only publish prices we can verify. Where there is no live price data, the button reads "check price on Amazon" and opens the retailer's own listing so the number you see is current. We will never show a remembered or stale figure.

Affiliate commissions, and no. When you buy through a link here the retailer pays us a commission at no extra cost to you. It does not change the ranking order, what we say about a product, or our willingness to tell you to spend nothing. Full disclosure.

Yes, and it is welcome. Tell us the size and number of floors, which room is bad and where the router is, what is between them, and your internet provider. Email contact@meshandsignal.com or use the contact form.
