An iPhone has three features that can make a perfectly good network look broken — and a network has several faults that look exactly like an iPhone problem. Start by telling them apart.

If the iPhone is the only device dropping, start with three iOS settings: Private Wi-Fi Address, Auto-Join on a competing network, and Wi-Fi Assist. If everything in the house drops, the phone is innocent and the network needs attention. Separating those two cases takes one minute and saves an afternoon.
The one-minute test
Next time it drops, pick up a second device — a laptop, a tablet, anything — and see whether it is still connected and still working. One device affected means a device problem. Everything affected means a network problem, and Wi-Fi keeps dropping and reconnecting is the page that covers it properly.
If it is only the iPhone
Private Wi-Fi Address. iOS presents a randomised MAC address to each network. Most routers do not care, but anything using MAC filtering, a captive portal or static DHCP reservations will. Settings → Wi-Fi → the i next to your network → turn Private Wi-Fi Address off for your home network only.
Auto-Join on a neighboring or guest network. If the phone has ever joined a neighbor's network, an open hotspot or your own guest SSID, it will hop to it at the edge of coverage and look like a drop. Forget every network you do not want it on.
Wi-Fi Assist. Settings → Cellular → bottom of the page. It silently switches to mobile data when Wi-Fi is weak, which presents as “the Wi-Fi dropped” and also quietly spends your data allowance.
Stale network settings. Forget the network on the phone and rejoin it. If that does not hold, Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
Low Power Mode and a very low battery both reduce radio activity, which can turn a marginal signal into a dropped one.
Worth knowing
Turning the Private Wi-Fi Address off is a home-network-only fix
Leave it on for public networks — randomising your MAC address stops cafes, airports and shops tracking your device between visits. The setting is per-network, so switching it off for your home Wi-Fi costs you nothing elsewhere.
If every device drops, these are the usual causes

The roaming case is the one most often mistaken for an iPhone fault. A phone holds on to a weak access point longer than you would like, and with a plain extender it may hold the original router all the way across the house. Systems with proper handover fix it; the detail is in mesh versus an extender.
What not to do
Do not disable 5 GHz, do not turn off WPA3 unless something genuinely ancient needs it, and do not reset the router to factory defaults as a first step — all three are commonly recommended, all three usually make the network worse, and none of them address the iOS settings above.
If the drops are specifically on calls rather than general use, Teams and Zoom calls dropping on Wi-Fi is the right page — calls fail on jitter and packet loss, which a speed test will not show you.
How we picked
We do not run a test lab. Rankings here are built from the manufacturers' published specifications, measurements taken by independent outlets that do have labs, and the structural reasoning on this site about what a given house or job actually needs. Every product was checked as currently sold before it was included. Where a figure appears it is attributed and linked in Sources; where we have no basis for a claim, it is left out. Our methodology sets out exactly what we will and will not assert.

Amazon eero 6+A dedicated 5 GHz backhaul band and about 1,500 sq ft per node. Roaming between nodes is the thing mesh systems do best, and a phone that drops as you move between floors is describing a roaming failure rather than a signal failure.
TP-Link Deco X55About 6,500 sq ft as a three-pack with three Gigabit ports per node. The value answer when the drops are coverage rather than iOS, and the ports mean you can wire the backhaul later.
TP-Link Archer AX21AX1800 with WPA3, OneMesh and EasyMesh, covering what TP-Link describe as a three-bedroom house. If your drops started with a years-old ISP box and a new iPhone, modern security and band steering is the inexpensive first move.

What it gets right
+The easiest setup of anything in this category, by a wide margin
+A dedicated backhaul band at a budget price is unusual and matters more than the headline speed
+Deep Alexa and smart-home integration if that is the household
What to watch for
−Wi-Fi 6, so no 6 GHz headroom for the future
−Fewer Ethernet ports than a Deco at similar money

Common questions
Why does my iPhone keep disconnecting from Wi-Fi but other devices do not?+−
Usually one of three iOS features: Private Wi-Fi Address conflicting with your router's MAC filtering or DHCP reservations, Auto-Join pulling the phone onto another network at the edge of coverage, or Wi-Fi Assist switching to cellular when the signal weakens. All three are per-network settings you can change.
Should I turn off Private Wi-Fi Address on my iPhone?+−
On your home network, yes, if you are getting drops — it removes a common conflict with routers that use MAC-based rules. Leave it enabled on public networks, where randomising the address genuinely protects you from being tracked between visits.
Does resetting network settings fix iPhone Wi-Fi drops?+−
Often, and it is worth doing after the targeted settings above rather than before. It clears stale network profiles and saved networks the phone may be hopping to. Note that it also erases every saved Wi-Fi password on the device.
Why does my iPhone drop Wi-Fi when I move around the house?+−
That is a roaming problem, not a phone problem. The phone is holding on to a distant access point instead of switching to a nearer one. Extenders with a separate network name make it worse; a mesh system with proper handover, or matched EasyMesh hardware, fixes it.
