The thing that caps a gigabit plan is almost never the radio. It is a 1 Gbps WAN port doing about 940 Mbps on a good day — and that is before Wi-Fi gets involved.

For a 1 Gbps plan, buy the TP-Link Archer BE550 — tri-band Wi-Fi 7 with 2.5 Gbps ports, which is the spec that actually determines whether you ever see your full plan. Almost every “my gigabit internet is only getting 600 Mbps” story ends at a port or a modem, not at the Wi-Fi. Check the ports first and you may not need a router at all.
Why a 1 Gbps plan needs a faster-than-1-Gbps port
A Gigabit Ethernet port negotiates at 1,000 Mbps and, after Ethernet and TCP/IP overheads, passes roughly 940 Mbps of usable throughput in ideal conditions. If your plan is sold as 1,000 Mbps or 1,200 Mbps, a Gigabit WAN port on the router is a hard ceiling slightly below what you are paying for, and no setting changes it.
That is why every router on this page has at least one 2.5 Gbps port. The headroom is not there so you can go faster than your plan; it is there so the port stops being the bottleneck. The full explanation, including what 2.5G and 10G actually buy a home, is in multi-gig ports explained.

Where a 1 Gbps plan gets capped, in the order worth checking.
Scroll the table sideways to see every column.
Test wired before you buy anything
Plug a laptop directly into the router with a Cat5e or better cable and run a speed test. If the wired result is near 940 Mbps, your modem and your plan are fine and any shortfall is Wi-Fi — a router or a second radio will help. If the wired result is well under that, the problem is upstream of the Wi-Fi entirely and a new router fixes nothing. Internet fast but Wi-Fi slow works through the split in detail.
Worth knowing
Most devices cannot use a gigabit over Wi-Fi anyway
A phone two rooms away from the router will not see 940 Mbps, and that is normal rather than broken. What a gigabit plan really buys a household is headroom when six people are using it at once — the sum, not the single-device number. If one device at full speed is the goal, the answer is a cable, not a better radio.
If you are on cable, check the modem first
On a cable provider the modem is as likely to be the cap as the router. A gigabit plan needs DOCSIS 3.1, and ideally a 2.5 Gbps Ethernet port on the modem so the modem-to-router hop is not the new bottleneck. Best cable modem for Xfinity is organized by speed tier, and modem-router combos versus separate boxes covers whether you want two boxes at all. On fiber the equivalent check is the ONT and the gateway your provider supplied — do I need a new router for fiber.
What you can safely ignore at this speed
Quoted aggregate Wi-Fi numbers. BE19000, AX6000 and the rest add up every band at once and no single device sees any of them.
Link aggregation unless your provider actually sells above 1 Gbps and your modem supports it. It is a workaround for routers without a multi-gig port.
Gaming-branded QoS. On a gigabit plan congestion is rarely the constraint; gaming routers explains what the features do and do not fix.
Buying mesh for speed. Mesh solves coverage. If one room is slow, see mesh versus a router before assuming a bigger system is faster.
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.

TP-Link Archer BE550Tri-band Wi-Fi 7 with 2.5 Gbps ports, so the wired path has headroom above your plan instead of sitting exactly on it. Independent testing measured over 3 Gbps on 6 GHz at close range and full gigabit-plus over the wire — which is all a 1 Gbps plan can ever ask for.
TP-Link Archer BE550 ProA 10 Gbps WAN/LAN port and four 2.5 Gbps LAN ports. Overkill for 1 Gbps on day one, and the right buy if your provider is already selling 2 Gbps in your area — the port is the part of a router that ages worst, and this one will not.
ASUS RT-BE86UWi-Fi 7 with ASUS's full feature set behind no paywall and AiMesh, so a gigabit plan that currently reaches one floor can be extended without replacing the router. The pragmatic choice when the plan is fast and the house is awkward.
TP-Link Archer BE230Dual-band Wi-Fi 7 with two 2.5 Gbps ports, which is the spec that matters here, and tested coverage across a 3,500 sq ft home. No 6 GHz band — so it is the value answer rather than the fast answer, and on a 1 Gbps plan most people will not notice the difference.

What it gets right
+Gets you the genuinely useful Wi-Fi 7 features — multi-link operation and 320 MHz channels — rather than the badge on dual-band hardware
+2.5 Gbps ports mean it will not cap a fiber or multi-gig cable plan
+Independent testing measured over 3 Gbps on the 6 GHz band at close range
+Vertical tower design takes less shelf space than the antenna-covered alternatives
What to watch for
−6 GHz range is short, so the headline number only applies within a room or two

Common questions
Do I need a special router for 1 gig internet?+−
You need one with a WAN port faster than 1 Gbps. A Gigabit WAN port passes about 940 Mbps after overheads, which sits just below a gigabit plan, so a 2.5 Gbps WAN port is the practical requirement. The Wi-Fi standard matters much less than that one port.
Why am I only getting 600 Mbps on a 1 gig plan?+−
Test wired first. If a laptop plugged into the router also reads 600 Mbps, the cap is the modem, the WAN port or the cable between them. If wired reads near 940 Mbps and Wi-Fi reads 600, that is normal Wi-Fi behavior at distance and the fix is coverage rather than a faster plan.
Is Wi-Fi 7 necessary for a gigabit plan?+−
No. A good Wi-Fi 6 router will carry a gigabit plan to nearby devices. Wi-Fi 7 helps most in a congested building and on a plan above a gigabit. What is necessary is the multi-gig port, which many Wi-Fi 7 routers happen to have.
Will a mesh system slow down my gigabit internet?+−
A mesh node on wireless backhaul typically delivers a fraction of a gigabit to devices connected through it, because the node is splitting airtime between you and the router. Wire the backhaul, or use a system with a dedicated backhaul band, and the loss largely disappears.
