WiFi Range Explained: How Far Does a WiFi Signal Reach?
A typical home WiFi router reaches about 150 feet (45 meters) indoors and up to 300 feet (90 meters) outdoors on the 2.4 GHz band, and about 50 to 75 feet (15 to 25 meters) indoors on the faster 5 GHz band. The newest 6 GHz band (WiFi 6E and WiFi 7) reaches a little less than 5 GHz. Those are best-case numbers in open space; in a real house, every wall, floor, and appliance between you and the router cuts the range, and speed drops well before the signal disappears entirely.
For most homes that means one router covers about 1,500 to 2,500 square feet on a single floor. If your house is bigger than that, has two or more floors, or has brick, plaster, or concrete walls, expect weak spots, and plan on a mesh system rather than a stronger router.
How far does each WiFi band reach?
Each WiFi band trades range for speed: 2.4 GHz goes farthest and is slowest, 6 GHz is fastest and goes least far, and 5 GHz sits in between. Most routers made since 2015 broadcast 2.4 and 5 GHz at the same time and hand your devices between them.
2.4 GHz
Indoor range: about 150 feet (45 m).
Outdoor range: up to 300 feet (90 m) with a clear line of sight.
Best for: smart-home devices, printers, and anything far from the router. It's the band that reaches the garage and the back porch, but it's crowded (microwaves, baby monitors, and every neighbor's router share it) and slow by today's standards.
5 GHz
Indoor range: about 50 to 75 feet (15 to 25 m).
Outdoor range: roughly 100 to 150 feet (30 to 45 m).
Best for: phones, laptops, TVs, and game consoles within a few rooms of the router. Much faster than 2.4 GHz and far less interference, but walls stop it sooner.
6 GHz (WiFi 6E and WiFi 7)
Indoor range: about 40 to 60 feet (12 to 18 m), slightly less than 5 GHz.
Best for: the fastest speeds in the same room or the next one. It needs a WiFi 6E or WiFi 7 router and a 6E/7 device; most phones and laptops sold since 2023 support it.
What about WiFi 6 and WiFi 7 range?
WiFi 6 (on 2.4 and 5 GHz) doesn't reach farther than WiFi 5, but it holds speed better at the edge of the range and handles more devices, so it feels like better coverage.
WiFi 7 adds the 6 GHz band and can use two bands at once, which improves speed at a distance, not the distance itself. Range is set by the band, not the WiFi generation.
How much do walls and floors reduce WiFi range?
Each interior wall cuts WiFi range by roughly a quarter, and a floor or a brick or concrete wall cuts it by half or more. Distance alone rarely kills a home WiFi signal; walls do.
Here is how different materials affect WiFi range:
- Drywall interior wall: small; two or three of them are fine on 2.4 GHz, one or two on 5 GHz.
- Wood floor or ceiling: moderate; expect a noticeable speed drop on the floor above or below.
- Plaster and lath (common in older Chattanooga homes): the metal lath behind plaster acts like a screen and blocks a large share of the signal.
- Brick, stone, or concrete: heavy loss; one exterior brick wall can end 5 GHz coverage on the other side.
- Metal and glass: a refrigerator, a metal-backed TV, a mirror, or a large window can block or reflect the signal outright.
- Water: a fish tank or a water heater absorbs 2.4 GHz especially well.
So "150 feet" becomes 150 feet down an open hallway, about 100 feet through two drywall walls, and maybe 40 feet through a brick wall.
Can WiFi go through walls?
Yes. WiFi goes through drywall, wood, and glass with some loss, through plaster and brick with heavy loss, and barely through concrete or metal. Lower frequencies penetrate better, which is why 2.4 GHz reaches rooms that 5 GHz can't. If a room on the far side of a brick or plaster wall has no signal, no router setting will fix it; a mesh node or a wired access point on that side of the wall will.
Can WiFi reach 300 feet?
Outdoors, with nothing in the way, 2.4 GHz can reach about 300 feet. Indoors, no home router reaches 300 feet. To get WiFi to a detached garage, a shop, or a neighbor's building 200 to 400 feet away, use an outdoor point-to-point wireless bridge (two small directional antennas, one on each building) or run an Ethernet cable and put a second access point in the far building. Both cost less than most people expect, and both work far better than an extender aimed out a window.
How far does a phone hotspot reach?
A phone's WiFi hotspot reaches about 30 to 50 feet (10 to 15 m) indoors, much less than a home router. Phones use small antennas and low power to protect the battery, and most hotspots default to 5 GHz or a low-power 2.4 GHz mode. For a car, a hotel room, or a patio it's plenty; for covering a house it isn't. Keep the phone in the same room as the devices using it.
Does WiFi slow down the farther you are from the router?
Yes. Speed falls off well before the signal does: a device at the edge of the range may still show one or two bars but get a tenth of the speed it gets next to the router. As the signal weakens, the router and device step down to slower, more reliable data rates, and a doubling of distance can cut speed by a third or more. If a room has a signal but video buffers there, that's why.
How do you check your WiFi range?
Walk your home with a phone and watch the signal in dBm, not bars. A free WiFi-analyzer app shows it as you move: −50 dBm is excellent, −65 dBm is good for anything, −75 dBm is where video and calls start to struggle, and −85 dBm is unusable. Note where you cross −70; that's the edge of your useful range.
Then run a speed test next to the router and again at the far edge. If the far result is under about a third of the near one, that room needs help.
How can you extend your WiFi range?
Follow these steps to extend the range of your WiFi:
- Put the router in a central, open, elevated spot. A router in a closet or a basement corner wastes half its range. See where to put your WiFi router.
- Use a mesh system with one node per floor or per far wing. Mesh nodes talk to each other on a dedicated band, so they don't halve your speed the way extenders do.
- Run Ethernet to a second access point for a detached building, a basement, or a room behind brick. It's the best-performing option and the most reliable.
- Use an extender for a single dead room when nothing else is practical. It works, but it relays at half speed. See how WiFi extenders work.
- Replace an old router. A WiFi 5 router from 2016 doesn't reach farther than a new one, but it drops speed faster at the edge and struggles with today's number of devices. See how long modems and routers last.

Frequently asked questions
What is the maximum distance for WiFi?
About 300 feet outdoors on 2.4 GHz with a clear line of sight, and about 150 feet indoors. Specialized outdoor point-to-point equipment with directional antennas can link two buildings a mile or more apart, but that's a different kind of WiFi than a home router.
What is WiFi range in meters?
Roughly 45 meters indoors and 90 meters outdoors on 2.4 GHz; 15 to 25 meters indoors on 5 GHz; 12 to 18 meters on 6 GHz.
How far can you be from the router and still get full speed?
Within about 30 feet and two walls on 5 GHz, or about 60 feet and three walls on 2.4 GHz. Beyond that you'll still connect, but speed drops with every foot and every wall.
Does a WiFi booster or extender reach farther than the router?
No. An extender rebroadcasts the router's signal from a new spot, so it reaches about as far from the extender as the router does from itself, roughly 50 to 150 feet depending on band. Placing it halfway to the dead zone, where it still gets a strong signal, is what makes it work.
Do I need a long-range router?
Rarely. Routers sold as "long range" use higher-gain antennas that add maybe 20 to 30 percent of range in the open, and none of that survives a brick wall. For a big or multi-story home, a mesh WiFi system beats any single router.
