The best Wi-Fi extenders
An extender fixes one or two weak rooms for $20 to $130. These are the ones worth buying, which kind works with your router, and when mesh is the better buy.
For most homes, buy the TP-Link RE615X ($59.87): Wi-Fi 6, an Ethernet port and up to 2,100 sq ft. On a budget, the TP-Link RE315 ($22.97) fixes one weak room. Any of them works with any router. If several rooms are weak, a mesh kit like the TP-Link Deco X55 3-pack ($149.96) is the better buy.
Our picks
Dual-band Wi-Fi 5, rated for up to 1,600 sq ft and 32 devices. Amazon's "Overall Pick" with 4.2 stars from more than 45,000 ratings. It has a 100 Mbps Ethernet port, fine for a printer or streaming box. Wirecutter's top pick. Good for one weak room in an apartment or small house. On sale at $22.97 (list $29.99).
Wi-Fi 6, up to 2,100 sq ft and 64 devices, plus a gigabit Ethernet port, so it can also run as a wired access point or feed a TV or game console. 4.2 stars from about 1,900 ratings. The best balance of speed and price for plans up to about 500 Mbps.
Wi-Fi 5 with three antennas and a gigabit Ethernet port, up to 2,200 sq ft. 4.3 stars from 18,600 ratings. If you don't need Wi-Fi 6, it covers more space than the RE315 for about $27 more.
Faster Wi-Fi 6, up to 2,400 sq ft and 64 devices, with an Ethernet port. 4.1 stars from 4,400 ratings. Worth it on a gig plan where a cheaper extender would be the bottleneck. PCMag and BroadbandNow both rank it their top extender.
Dual-band Wi-Fi 7 with a 2.5G Ethernet port. 4.2 stars from about 200 ratings. Only worth it with a Wi-Fi 7 router and newer devices; on sale at $129.98 (list $149.99).
Dual-band Wi-Fi 5, up to 1,500 sq ft and 25 devices. 4.0 stars from 16,500 ratings. A good alternative if the RE315 is out of stock.

What Wi-Fi extender works with my router?
Any standard extender works with any router, including the gateway your provider gave you. The difference is whether it joins your router's network seamlessly or shows up as a second one.
| Your router | What works |
|---|---|
| Any router (Xfinity, Spectrum, AT&T, Fios, your own) | Any standard extender works. It may show as a second network name. |
| TP-Link router with OneMesh or EasyMesh | A TP-Link RE-series extender joins the same network seamlessly. |
| ASUS router with AiMesh | An ASUS extender such as the RP-BE58 ($85.78), or another ASUS router, as a mesh node. |
| eero system | Only an eero unit, such as the eero 6 extender ($79.99). Other extenders work but don't join the mesh. |
| Verizon Fios router | Verizon's own extenders for one network; see our Verizon extender guide. |
| Provider gateway that supports its own pods (Xfinity, Spectrum, Cox) | Ask the provider: their pods or extenders join the gateway's network, and some plans include them. |
Before you buy: is it your Wi-Fi or your plan?
Run a speed test right next to the router, then in the slow room. If it's slow next to the router too, an extender won't help; the problem is your plan or your provider. Our guide to why your internet is slow covers the fixes, and testing Wi-Fi room by room shows how to find dead zones.
How to set up a Wi-Fi extender
- Plug it in near the router for setup, or follow the app (TP-Link Tether, NETGEAR Nighthawk).
- Connect it to your Wi-Fi with the WPS button on both devices, or by choosing your network in the app.
- Move it halfway between the router and the weak room. Use the signal light to find a spot with a good connection.
- Use the same network name and password if the app offers it, so devices switch on their own.
- Test the weak room again. If it's still slow, move the extender one room closer to the router.
If there's an Ethernet jack near the weak room, connect the extender to it and use access point mode. You'll keep your full speed instead of losing about half over the air.
The best Wi-Fi extender for your provider
Your provider's own extender or pods usually join your network most smoothly, and some plans include them. Ask first, then buy one of the picks above if it isn't free.
| Provider | Best option |
|---|---|
| Xfinity | Ask about WiFi Boost Pods, which join the gateway's network. Any extender above also works. With your own mesh, put the gateway in bridge mode. |
| Spectrum | Spectrum offers WiFi Pods that pair with its router; ask whether your plan includes them. Any extender above works too. |
| AT&T Fiber | Ask AT&T for its Smart Wi-Fi Extender, which pairs with the AT&T gateway. A third-party extender or mesh also works; mesh goes behind the gateway in passthrough mode. |
| Verizon Fios | Verizon includes an extender on 1 Gig and faster plans. See which Verizon extender works with your router. |
| T-Mobile or Verizon 5G Home | Any extender works with the gateway's Wi-Fi. T-Mobile's All-In plan includes a mesh Wi-Fi extender on request. For a whole house, plug a mesh system into the gateway's Ethernet port. |
| Starlink | Starlink sells its own mesh units that pair with its router. Third-party extenders work with Starlink Wi-Fi; a mesh system needs Starlink's Ethernet adapter on routers without a port. |
Gaming, thick walls, garages and long range
- Gaming: any wireless extender adds lag. Run an Ethernet cable, or connect the extender's Ethernet port to the router and use access point mode. If cable isn't possible, the RE715X or a Wi-Fi 7 model like the RE403BE adds the least delay.
- Thick walls: put the extender where it still has a clear path to the router, such as a hallway or doorway. If brick or plaster blocks it, a wired connection over coax (MoCA adapters) or a mesh system with wired backhaul works better.
- Garage or detached building: an indoor extender near the wall facing the garage often reaches it. For a separate building, an outdoor access point or an Ethernet run from the house is more reliable.
- Long range: ignore "10,000 sq ft" claims; see the best long-range extenders. Real coverage depends on walls and distance. Two mesh units, or a wired access point, cover far more than any plug-in extender.
More on that choice in mesh vs. an extender.
When to buy mesh instead
For a home over about 2,000 sq ft, more than one floor, or several weak rooms, a mesh kit covers more for not much more money. Two TP-Link kits on Amazon cost less than one Wi-Fi 7 extender:

Check with your provider first
Some providers include extenders or pods, or rent them cheaply: Verizon Fios includes one on 1 Gig and faster plans, and Xfinity, Spectrum and Cox offer pods that pair with their gateways. If yours is free, start there. If you rent a gateway, our guide to buying your own modem and router shows what you could save.
Questions
Which is better, a Wi-Fi booster or an extender?
They're the same thing. "Booster", "repeater" and "extender" are all names for a device that picks up your router's Wi-Fi and rebroadcasts it. Compare them by Wi-Fi generation, coverage and whether they have an Ethernet port, not by the name.
What is the strongest Wi-Fi extender?
Tri-band Wi-Fi 7 models like the TP-Link RE653BE ($199.99) are the most powerful plug-in extenders. For most homes, the RE715X or RE615X does the job for much less. If you need more range than that, buy mesh.
What is the best Wi-Fi extender for Xfinity?
Ask Xfinity about WiFi Boost Pods first, since they join the gateway's network. Otherwise, the TP-Link RE615X or RE715X works well with any Xfinity gateway.
What Wi-Fi extender works with my router?
Any standard Wi-Fi extender works with any router. To get one seamless network, match the brand's mesh system: TP-Link OneMesh or EasyMesh extenders with TP-Link routers, ASUS AiMesh with ASUS, eero with eero, and your provider's own pods with its gateway.
What is the best Wi-Fi extender?
For most homes, the TP-Link RE615X ($59.87) is the best value: Wi-Fi 6, an Ethernet port, and coverage up to 2,100 sq ft. The TP-Link RE315 ($22.97) is the best cheap one.
Do Wi-Fi extenders really work?
Yes, for one or two weak rooms. A wireless extender cuts the speed it passes on roughly in half, so it helps most where you had almost no signal. For a whole house, mesh works better.
Where should I put a Wi-Fi extender?
About halfway between the router and the weak room, in a spot that still gets a good signal. Most extenders have a light that shows whether the signal is strong enough there.
Is mesh better than an extender?
For a large or multi-story home, yes. A mesh kit like the TP-Link Deco X55 3-pack ($149.96) gives one network that devices move through on their own. An extender is cheaper for a single dead spot.
Are the cheap "15,000 sq ft" Wi-Fi boosters any good?
Be skeptical. No plug-in extender covers 10,000 to 15,000 sq ft; those claims, often on new listings with a few dozen reviews, aren't realistic. Stick to TP-Link, NETGEAR, ASUS or eero models with thousands of ratings.
