An apartment is small enough that any router reaches every corner. Your competition is the twenty other networks in the building, and that needs a different plan.

In an apartment, buy for clean airtime and ignore coverage claims entirely. A 600 to 1,200 square foot space is inside the reach of any modern router. What you are fighting is a building full of routers all having to take turns, and the shopping list for that is close to the opposite of a large house's.
Why your signal is strong and your speed is not
Wi-Fi is polite by design: a device listens before transmitting and defers if it hears anything. In a building where every apartment has a router, everyone spends most of their time waiting for everyone else. Signal strength stays high — you are close to your own router — while throughput collapses, and it is worst in the evening when the building is full.
There are only three non-overlapping 2.4 GHz channels in the US (1, 6 and 11), and in a dense building all three are occupied several times over. 5 GHz has far more room. 6 GHz is the real escape: fewer devices use it, and crucially its short range means your neighbors' 6 GHz traffic mostly does not reach you at all. In an apartment, the short range of 6 GHz is a feature.
The free fixes, which matter more here than anywhere
Set 2.4 GHz manually to channel 1, 6 or 11, at 20 MHz. Never auto, never 40 MHz in a dense building, and never a channel like 3 that overlaps two others.
Move every capable device to 5 GHz.
Try the upper 5 GHz channels. Often the emptiest, as some hardware avoids them.
Move the router away from the shared wall and the kitchen. Both matter: the shared wall is where your neighbor's router is, and the kitchen is where the microwave is.
Turn transmit power down, if you can. Genuinely. Details below.
Wire the desk and the TV. Every device you take off the air is airtime returned to the ones that need it.
Turning the power up makes it worse for you, not just for them
Shouting louder means every neighboring router must wait longer for you, so they retransmit more, so the air gets noisier for everybody including you. In dense housing the better engineering is lower power over a shorter range, which is also why a wall or ceiling access point with adjustable power beats a maximum-power consumer router in an apartment.

When an apartment does need two radios
Three cases, and only three: a long narrow layout with a solid wall across the middle; a two-floor or split-level apartment; and a converted building with masonry internal walls, which behaves like a solid-wall house rather than an apartment. Otherwise one router in a sensible spot is the right answer and a second radio is a downgrade.
We do not run a lab. Specifications are the manufacturers'; performance context comes from the independent outlets named in Sources. The scores weigh those inputs against the specific building on this page, and the rubric is printed on every pick so you can disagree with the weighting. What we do and do not assert.

TP-Link Archer BE9700A 6 GHz radio is a band your neighbors are mostly not on, and its short range is an advantage in an apartment rather than a drawback.

What it gets right
+Four 2.5 Gbps LAN ports is rare and makes it a real hub for a wired house
+A 10 Gbps WAN/LAN port means the router will outlive several internet plans
+Tri-band including 6 GHz, so close-range devices get a clean fast lane
What to watch for
−One box cannot beat physics — it will not cover a three-story house on its own

Common questions
Why is my apartment Wi-Fi slow with a strong signal?+−
Because Wi-Fi listens before transmitting and defers if it hears anything. In a building full of networks everyone spends most of their time waiting, so throughput collapses while signal strength stays high — and it is worst in the evening. The fix is a less crowded band, not a stronger signal.
Do I need a mesh system in an apartment?+−
Usually not, and it can make things worse by adding another transmitter to already crowded air. The exceptions are a long narrow layout with a solid wall across the middle, a two-floor apartment, or a converted building with masonry internal walls.
What Wi-Fi channel is best in an apartment building?+−
On 2.4 GHz, whichever of 1, 6 or 11 has the weakest competing networks, set at 20 MHz width. On 5 GHz, the upper DFS channels are often emptiest. Better still, move to 6 GHz if your hardware supports it — its short range means neighbors' traffic mostly does not reach you.
