What is wrong with your Wi-Fi?
Pick the symptom that sounds like your house. Every one of these pages explains the cause, tells you how to confirm it, lists the free fixes first, and ends with a specific recommendation rather than a shrug.
- There is a dead zone somewhereThe complete diagnostic: what causes a dead zone, how to map yours, the free fixes first, then the right hardware for each cause.
- Upstairs is unusableA vertical coverage problem, not a broken router. The geometry, the test, and the fix ranked by cost.
- The basement has nothingConcrete, ductwork and a floor in the way. Why wireless extenders disappoint here and which wired route to take.
- It is slow everywhereFive causes, one ten-minute test to separate them, and the fix for each — free ones first.
- Work calls keep droppingCalls fail on jitter and packet loss, not bandwidth. Why a passing speed test proves nothing, and the fixes that hold.
- Streaming keeps bufferingWhat 4K really needs, why the TV's own Wi-Fi is usually the weak link, and the fix that ends it permanently.
What we recommend, by category
The top pick from each of our roundups. Each one links to the page where it won, with our reasoning and the honest trade-offs. Product photography and prices come from each product's own Amazon listing, checked daily — so what you see here is the current listing, not a number we remembered.
Best for large homes
TP-Link Deco BE63
Score 9.0/10 · The best coverage per dollar in Wi-Fi 7
Tri-band Wi-Fi 7 rated to about 7,600 sq ft as a three-pack, at a price the premium systems do not approach.
#ad We earn a commission if you buy through this link. It never changes the ranking.
Best for ~3,000 sq ft
TP-Link Deco XE75 Pro
Score 9.1/10 · The sweet spot at this size
A tri-band two-pack rated to about 5,500 sq ft with a dedicated 6 GHz backhaul — comfortably enough here, without Wi-Fi 7 pricing.
#ad We earn a commission if you buy through this link. It never changes the ranking.
Best for ~2,000 sq ft
Amazon eero 6+
Score 8.6/10 · The easiest good answer at this size
A dedicated 5 GHz backhaul at a budget price, about 1,500 sq ft per node, and the least frustrating setup in the category.
#ad We earn a commission if you buy through this link. It never changes the ranking.
Best for 5,000 sq ft +
Netgear Orbi 970
Score 8.9/10 · The only brute-force answer to wireless backhaul
Quad-band, with a second 6 GHz radio so the nodes stop competing with your devices. At this size that is worth the money.
#ad We earn a commission if you buy through this link. It never changes the ranking.
Best for gaming
TP-Link Deco BE63
Score 8.6/10 · The best-value gaming mesh
Wi-Fi 7 with multi-link operation and 2.5 Gbps ports at a midrange price — multi-link is the feature that keeps a session alive when one band gets noisy.
#ad We earn a commission if you buy through this link. It never changes the ranking.
Best budget systems
TP-Link Deco X55
Score 8.3/10 · The most coverage per dollar
Three nodes, about 6,500 sq ft, three Gigabit ports each. Wire the backhaul and it outperforms systems at triple the price.
#ad We earn a commission if you buy through this link. It never changes the ranking.
Best for wired backhaul
ASUS ZenWiFi BT10
Score 8.7/10 · 10 Gigabit ports with no subscription
10 GbE on both units and full control over how the backhaul is chosen, which is exactly what you want on a wired network.
#ad We earn a commission if you buy through this link. It never changes the ranking.
Best for 2 floors
TP-Link Archer BE550 Pro
Score 8.6/10 · Covering two floors from one box
Tri-band with external antennas you can angle, and four 2.5 Gbps LAN ports so the ground floor can be wired properly.
#ad We earn a commission if you buy through this link. It never changes the ranking.
Or start from what you already know
Most people know their internet provider and their house long before they know which product category they need. Either is a perfectly good place to begin.
How this site is different
We diagnose before we sell
Every symptom page lists the free fixes before the paid ones, and several of them will talk you out of buying anything at all.
We say what we have not tested
We do not run a lab. Recommendations are built from published specifications and independent testing by named outlets, cited on every page.
We name the mechanism
Not just what to do but why it works, so you can tell when our advice does not apply to your house.
We do not publish prices we cannot verify
Buy buttons carry the live Amazon price, re-checked daily and stamped with the date. If that check ever stops, the number disappears and the button simply says check price.
Read these first
The four pages that carry most of the argument on this site. Between them they cover how to find a problem, the specification that decides whether a mesh system works, the scope of what you should be buying, and how to stop renting your provider's box.
The diagnostic pillar
How to Find and Fix Wi-Fi Dead Zones
The complete diagnostic: what causes a dead zone, how to map yours, the free fixes first, then the right hardware for each cause.

Explainer
What Backhaul Is, and Why It Decides Everything
The single specification that decides whether a mesh system is good or disappointing, explained plainly.
Top pick · TP-Link Deco XE75 Pro · #ad price as of November 13, 2026
Head to head
Mesh Wi-Fi vs a Wi-Fi Extender
One or two bad rooms means an extender. Three or more means mesh. Why room count, not budget, decides it.

By provider
Best Routers and Mesh for Xfinity
The biggest equipment fee of the major providers, so the fastest payback. What works and what to buy.
