Scroll the table sideways to see every column.
The verdict in one line: if your internet speed is poor standing next to your current box, you need a router. If it is good there and poor in a specific part of the house, you need an access point. They are not alternatives to each other. Every network needs exactly one router; access points are optional extras that extend it properly rather than cheaply.
What each box actually does
A router is the manager. It takes the single connection your provider gives you, hands out private addresses to everything in the house, translates between those and the public internet, and firewalls the lot. Most home routers also contain a Wi-Fi radio, which is why the two jobs get confused — but the radio is a feature bolted onto the router, not what makes it a router. If you removed the radio it would still be one.
An access point is just that radio, on the end of a cable. It has no addressing role, no firewall, no opinion about your internet connection. It receives Ethernet and turns it into Wi-Fi, which is a small job done extremely well — because a cable, unlike a wireless relay, costs nothing in throughput. The background on the boxes themselves is in router vs modem vs gateway.
Choose a router if…
Speed is poor next to the box. Definitive. Nothing downstream can be better than what the router itself produces, and adding an access point will faithfully deliver the same poor number somewhere else.
You are still on your provider's gateway. Usually the weakest hardware in the house, and often rented. How and whether to.
You want the option of adding nodes later. A router with AiMesh or EasyMesh lets a coverage problem become an addition rather than a replacement.
Choose an access point if…
The router is fine and one area is not — a far wing, a finished basement, a detached garage, an upstairs floor.
You can run one Ethernet cable to that area, or you already have coax there and can use MoCA to make it Ethernet.
You tried an extender and it disappointed. An access point is the same idea without the halving — see extender vs access point.
You want the radio on the ceiling. Coverage from above through one floor beats coverage from a shelf through five walls, and only an access point can be mounted up there.
Try this first
Your old router can be the access point
Most routers have an "access point mode" or "AP mode" in their settings. Switch the old one into it, run a cable from the new router to it, give it the same network name and password, and you have a second coverage point for nothing. It will not roam as smoothly as a matched pair, but it costs nothing and it answers the question of whether coverage is really your problem before you spend anything.
Why most houses end up with both
The two problems are sequential rather than exclusive. People replace a tired provider gateway with a decent router, enjoy a genuine improvement, and then discover the far bedroom is still weak — because distance was always a second, separate problem that the speed improvement masked. At that point one cable and one access point finish the job.
This is also why we recommend routers that support a mesh standard. If you buy a router that can accept a node, your second purchase is a node; if you buy one that cannot, your second purchase is a whole system.
The case against both
If three or more rooms are bad, buy neither. Stacking an access point onto an aging router to cover a whole house that is weak everywhere is more work and often more money than a mesh system, which replaces the router and the coverage problem in one purchase with one network name and managed roaming. Mesh versus access points is the comparison for that decision.
And if you cannot run a cable, an access point is off the table. It is the one hard requirement. Without Ethernet or a wired substitute, the honest options are an extender with its throughput penalty, or mesh with a wireless backhaul. Both are worse than a cable and better than nothing.
The verdict
Buy a router if you have none, if yours is rented, or if the speed is bad where the signal is strongest. The ASUS RT-BE86U is our pick because AiMesh keeps the next decision cheap. Buy an access point if your router is already good and a specific area is not, and you can get a cable there: the TP-Link Omada EAP610 if cost matters, the UniFi U7 Pro if you want Wi-Fi 7 on a cable you are only going to run once. Buy neither if the house is weak in several places at once — that is a mesh purchase.
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.

What it gets right
+External adjustable antennas, which is a real advantage across two floors where sealed internal antennas give you no control
+AiMesh means a coverage problem later is an added node rather than a new router
+Security, parental controls and VPN features included rather than subscribed
+ASUS keeps firmware coming for its routers for an unusually long time
What to watch for
−The settings depth that makes it good also makes it the wrong pick for someone who wants an app and nothing else
−Premium pricing for a single box
−Physically large with visible antennas, which matters if it has to live in a living room

Common questions
What is the difference between a router and an access point?+−
A router runs the network — it hands out addresses, performs NAT, firewalls traffic and connects you to the internet. An access point only turns an Ethernet cable into Wi-Fi coverage. Every network needs exactly one router; access points are optional additions that extend coverage with no throughput penalty because they are wired.
Do I need a router if I have an access point?+−
Yes. An access point cannot run a network on its own — it has no addressing, no firewall and no connection to your provider. It only adds coverage to a network a router is already running.
Can I use an old router as an access point?+−
Usually, yes. Most routers have an access point or AP mode in their settings. Switch the old unit into it, run Ethernet from the new router, and give it the same network name and password. Roaming will not be as smooth as a matched system, but it is free and it proves whether coverage is really your problem.
Is an access point better than a router for coverage?+−
For adding coverage to a specific area, yes — because you put it where the coverage is needed rather than where the incoming line enters the house, you can mount it on a ceiling, and the cable means no throughput is lost. It cannot replace the router, only extend it.
