How this page is funded: some links here are affiliate links, and Mesh & Signal earns a commission if you buy through them. It costs you nothing extra, it never changes which product we rank first, and we do not publish a price we have not verified. Full disclosure.
This is the best-value purchase in home networking, and it is not close. A sub-$100 router is generally better hardware than the gateway your provider rents you, and if you pay a monthly equipment fee it pays for itself inside a year. Our pick is the TP-Link Archer AX21.
Worth knowing
On the price cap
Street prices move week to week and we do not publish a number we cannot verify, so the cap here is a selection rule rather than a quoted price: these are the routers whose established market position sits at or below it. Every button opens the retailer's live listing, so the figure you see is the current one — check it against the cap before you order, because that is the one thing on this page that can change.
What under $100 actually gets you
More than the price suggests, because Wi-Fi 6 has finished moving down market. At this cap you can expect dual-band Wi-Fi 6, four antennas, WPA3, OFDMA for a device-heavy house, four Gigabit LAN ports, and mesh compatibility so you can add a node later. TP-Link rates the AX21 for three-bedroom houses; independent testing measured the AX55 at over 800 Mbps at close range.
What you give up
Missing
Who it affects
A 6 GHz band
Apartment dwellers — 6 GHz is the empty band, and this is the real cost of buying cheap
Multi-gig ports
Anyone on a plan faster than about 940 Mbps; Gigabit ports cap you there
Processor headroom
Homes past roughly 30-40 connected devices, and anyone wanting a router-level VPN
Long-range consistency
Homes over about 2,000 sq ft or with masonry walls
None of these matter to every household. Check whether they matter to yours.
Scroll the table sideways to see every column.
If the first row is you, the honest answer is to stretch to the $200 bracket for a 6 GHz band — it is the single upgrade that changes the experience in a crowded building. If the last row is you, no router at any price on this page is the fix.
Try this first
Check the fee stops
The arithmetic that makes this the best-value purchase only works if the rental charge actually comes off your bill. It does not always happen automatically — you generally have to return the equipment and confirm the change. How to swap an ISP router properly, and provider pages for what each one charges.
When to spend nothing
Two cases, and they are common enough to put on the page.
If one room is dead and the rest is fine, that is coverage, not router performance. A $25 extender or — better — a wired access point solves it, and a new router will not. Confirm which you have.
If the signal is strong but everything is slow in the evening, that is congestion, and the fix is free: why Wi-Fi slows at night. Moving the router and choosing a clearer channel costs nothing and helps more than this purchase would.
One thing worth doing with the savings
Buy the cheap router and spend $30 of the difference on a long Ethernet cable. Wiring one access point, one console or one work desk does more for the household than the next $100 of router would — and it is the upgrade that keeps working through every future router you own.
How we picked
We do not run a test lab. These rankings come from manufacturers' published specifications, measurements taken by outlets that do have labs, and the structural reasoning on this site about what a given house needs. Every product was checked as currently sold before it was listed. Figures are attributed in Sources; claims we cannot support are left out rather than estimated. Our methodology sets out the whole rubric.

TP-Link Archer AX21AX1800 Wi-Fi 6, four antennas, WPA3 and EasyMesh, rated by TP-Link for three-bedroom houses. Nothing clever, nothing missing.
TP-Link Archer BE3600Covered a 3,500 sq ft test home consistently, and it is the cheapest Wi-Fi 7 router worth owning — dual-band, so the badge is longevity not speed.

What it gets right
+Four fixed antennas, a dual-core processor and OFDMA at a price that used to buy entry-level Wi-Fi 5
+WPA3 and guest networks on both bands, so replacing an ISP gateway does not mean giving up security features
+EasyMesh support means a second node can be added later rather than replacing the router
What to watch for
−Dual-band, so there is no 6 GHz band and no relief in a congested apartment building
−Gigabit ports only, which caps anything faster than a gigabit plan

Common questions
Is a router under $100 any good?+−
Yes, and generally better than the gateway your provider rents you. At this price you get dual-band Wi-Fi 6, four antennas, WPA3, OFDMA and mesh compatibility. TP-Link rates the Archer AX21 for three-bedroom houses, and independent testing measured the AX55 at over 800 Mbps at close range.
What do I give up buying a cheap router?+−
Four things: a 6 GHz band, which matters most in a crowded apartment building; multi-gig ports, which matter above about 940 Mbps; processor headroom for very device-heavy homes or a router-level VPN; and long-range consistency over about 2,000 sq ft.
Should I buy a cheap router or an extender?+−
A router if the whole house is slow, including next to the router. An extender if the house is fine except one or two rooms — that is coverage rather than performance, and a $25 extender or a wired access point fixes it where a new router will not.
