How to Improve WiFi Speed: 12 Ways to Make Your WiFi Faster
WiFi can run slow for more than one reason at once — distance from the router, the band you’re on, interference, too many connected devices, or simply an underlying Internet plan that’s already at its limit. This guide starts with the quickest fixes, then works through a fuller diagnosis and 12 concrete ways to improve your WiFi. Whatever you try, measure before and after so you know if it actually helped.

How to Improve WiFi Speed Quickly
Six things worth trying before anything else — in order, they fix the most common causes of slow WiFi first.
1. Move Closer to Your Router
WiFi signal weakens with distance and with every wall in between. Moving closer, or reducing what’s in the way, is the single biggest lever most people have.
2. Restart Your Router
Clears temporary memory and connection issues that build up over time. It won’t fix a weak signal or an outdated plan, but it’s a quick, low-risk first step.
3. Connect to 5 GHz or 6 GHz
When you’re close to the router, the 5 GHz or 6 GHz band (if your device supports it) is generally faster than 2.4 GHz.
4. Reduce WiFi Interference
Move the router away from microwaves, cordless phones and other electronics, and away from neighboring networks where possible.
5. Disconnect Devices You Don’t Need
Every connected device shares the router’s capacity. Disconnecting idle or unused ones frees that capacity up for the rest.
6. Test Your WiFi Speed Again
Run a test before and after each change. It’s the only way to know whether something actually helped.
Diagnosis
Why Is My WiFi So Slow?
Slow WiFi rarely comes down to one single cause. It can come from your distance to the router, walls and physical obstacles, interference from other networks, a crowded wireless channel, too many connected devices, an aging router or an aging device, the wrong WiFi band for your situation, poor router placement, network congestion, or simply an Internet connection that’s already close to its limit.
WiFi speed and Internet speed are not the same thing. Your Internet speed is what your provider delivers to your router. WiFi speed is the separate, additional link between that router and your device. A fast Internet plan does not automatically mean a fast WiFi connection — see the full comparison below for why the two can pull in different directions.
The Full List
12 Ways to Improve WiFi Speed
None of these guarantee a specific result, but together they address the most common causes of slow WiFi.
1. Move Your Router to a Better Location
Router placement affects every device on your network at once, which makes it one of the highest-leverage changes available. Aim for a central, open location rather than a corner of the house, and keep it out of closed cabinets or closets — enclosed spaces trap the signal instead of letting it spread.
Where possible, avoid placing it directly against thick or concrete walls, and keep it off the floor or tucked behind furniture; a shelf at roughly chest height in an open area usually works better than a spot on the ground. Keep some distance from other electronics that can add interference, covered in more detail below.
2. Use the Right WiFi Band
Most routers broadcast on more than one frequency band, and each one makes a different trade-off between range and speed. Picking the right one for your situation matters more than picking whichever is labeled “fastest.”
| Band | Range | Typical speed |
|---|---|---|
| 2.4 GHz | Longest range, passes through walls more easily | Usually slower, more congested |
| 5 GHz | Shorter range, more affected by obstacles | Generally faster, more capacity |
| 6 GHz | Shortest range, needs a clear path | Very fast at short range, on supported devices only |
6 GHz is only available if both your router and your device support WiFi 6E or WiFi 7 — older hardware simply won’t see that band. No single band is “always better”: close to the router, 5 GHz or 6 GHz will usually feel faster, while further away or through several walls, 2.4 GHz may hold a stronger, more usable connection.
3. Reduce WiFi Interference
WiFi shares the airwaves with more than just neighboring routers. Bluetooth devices, microwave ovens (which operate close to the 2.4 GHz band) and other radio-frequency equipment such as cordless phones and baby monitors can all add noise that competes with your signal.
A crowded WiFi channel — one with many nearby networks broadcasting on or near it — adds a similar kind of congestion, since every network sharing that channel has to take turns. Moving the router away from other electronics, and keeping walls between it and your neighbors’ routers where possible, both help.
4. Restart Your Router
A restart clears the router’s temporary memory and resets active connections, which can help if performance has quietly degraded after days or weeks of uptime. It is a reasonable first step precisely because it’s quick and low-risk — but it is not a universal fix, and it won’t do anything for a signal that’s weak because of distance, interference or an aging router.
5. Disconnect Unused Devices
Every device connected to your WiFi — active or simply idle — shares the router’s available capacity and a limited amount of airtime. A phone charging in a drawer, a smart speaker nobody’s using, or an old tablet still logged into the network all take a small share of that capacity.
This adds up faster in busy households: several people streaming, gaming or on video calls at the same time can create real congestion. Checking your router’s connected-devices list and disconnecting what you don’t recognize or need frees that capacity back up.
6. Update Your Router Firmware
Firmware updates from your router’s manufacturer typically focus on stability and security, and sometimes include performance improvements or bug fixes for specific WiFi issues. They’re worth keeping current for those reasons alone — just don’t expect an update to reliably deliver a faster connection on its own.
7. Update Your Device
The router is only one half of the WiFi connection; the client device is the other. An older smartphone, laptop, tablet, smart TV or game console may support an older WiFi standard, fewer antennas, or a slower maximum speed than your router is capable of — which caps your result regardless of how good the router is.
Keeping your device’s operating system up to date can also resolve WiFi driver bugs that affect real-world throughput. If one specific device is consistently slower than others on the same network, its own hardware or software is a likely place to look first.
8. Use Ethernet When Possible
For a desktop computer, a game console, a TV, or a work computer where stability and maximum throughput matter most, a wired Ethernet connection sidesteps WiFi’s variables entirely — no distance, no interference, no shared airtime with other devices. It’s usually the single most reliable way to get the full benefit of your Internet plan.
It’s not always practical for a phone or a laptop you move around the house, which is exactly where the tips above matter most. Compare a wired result with our Internet Speed Test against your WiFi result to see exactly how much the wireless link is costing you.
9. Reduce Distance and Obstacles
This is related to router placement, but worth calling out on its own: what’s physically between your device and the router matters as much as the distance itself. Concrete, brick, and dense masonry absorb WiFi signal noticeably more than drywall or wood.
Metal — in appliances, mirrors, ductwork or structural framing — reflects and blocks WiFi rather than passing it through. Floors and ceilings between rooms add up the same way multiple walls do, and large furniture like bookcases or aquariums can create a surprisingly effective dead spot right behind them.
10. Choose Better WiFi Channels
Within a band, WiFi is further split into channels, and a channel that’s heavily used by nearby networks behaves like a crowded road — everyone shares the same space and has to take turns. Many routers can select a channel automatically, and re-running that automatic selection, or manually testing a couple of alternatives, can sometimes find a quieter one.
On 2.4 GHz specifically, networks are commonly set to one of a few channels that don’t overlap with each other, as a general example rather than a fixed rule — the best channel for your home depends entirely on what your neighbors are using, and changes as they change theirs. There’s no universal “best” channel, only a currently-least-congested one.
11. Consider a Mesh WiFi System
A mesh system uses two or more units spread through your home to extend coverage further and more evenly than a single router usually can, which makes it worth considering in a larger home, a home with multiple floors, or one with persistent dead zones far from the router.
It’s worth being clear about what it does and doesn’t fix: a mesh system generally improves coverage and consistency across a larger area, but adding more equipment doesn’t automatically increase your maximum speed — that’s still capped by your Internet plan and by each unit’s own capabilities. It solves a coverage problem, not a bandwidth problem.
12. Test Your WiFi Speed Again
The only way to know whether a change actually helped is to measure it. A simple, repeatable approach: test first, make one change at a time, test again in the same spot, and compare the results.
Changing several things at once might improve your connection, but you won’t know which change did the work — or whether one of them quietly made things worse while another compensated for it.
WiFi vs Internet
WiFi Speed vs Internet Speed: What’s the Difference?
| Term | What it measures |
|---|---|
| WiFi speed | The connection between your device and your router, over the air |
| Internet speed | The connection between your home network and your ISP’s network |
A wired connection looks like this:
Router
Device
Over WiFi, there is one more link in the chain:
ISP
Internet connection
Router
WiFi
Device
A slow WiFi result does not necessarily mean your Internet plan is underperforming — it can simply mean the wireless leg of the journey is the bottleneck. The most reliable way to tell the two apart is to compare a wired Internet Speed Test with a WiFi Speed Test from the same device, one after the other.
Troubleshooting
What Causes Slow WiFi?
Usually one or more of these is behind a slow result.
- A weak signal at your location
- The router placed too far away
- Walls and physical obstacles
- Interference from other networks or devices
- A crowded WiFi channel
- Too many connected devices
- Outdated router hardware
- Outdated firmware or device software
- Poor router placement
- ISP or Internet plan limitations
- Network congestion
Narrow It Down
One Device or Every Device?
Slow on Every Device
If every device on your network is affected, the cause is more likely the router, the network as a whole, or your Internet connection itself — not any one device.
Slow on Only One Device
If just one device is slow while others are fine on the same network, look at that device first — its WiFi hardware, its software, or its distance from the router.

How to Improve WiFi in Every Room
Some rooms are simply harder for WiFi to reach. What helps depends on why.
Bedroom or Any Far Room
Try repositioning the router toward that side of the home first. If that’s not possible, 2.4 GHz will generally reach further than 5 GHz or 6 GHz from the same spot.
Upstairs or Downstairs
Floors and ceilings attenuate WiFi the same way walls do. A more central, vertically balanced router location often helps both levels at once.
Through Thick Walls
Concrete, brick and metal-backed walls are the hardest for WiFi to pass through. A wired access point on the far side of the wall sidesteps the problem entirely.
Persistent Dead Zones
If one area is consistently weak no matter what you try, a mesh system is worth considering — it addresses coverage gaps rather than any single room’s bad luck.
One Device
How to Improve WiFi Speed on Your Phone or Laptop
If one specific device is slow while others are fine, start here before touching the router.
- Move closer to the router and re-test.
- Forget the WiFi network on the device, then reconnect to it.
- Check which band it’s connected to, and try switching if both are available.
- Update the device’s operating system.
- Restart the device.
- Compare its result with another device on the same network, in the same spot.
- Run a WiFi Speed Test on it to get an actual number.
If that one device stays slow while others are fine on the exact same network, the device itself — not your router or your Internet plan — is the more likely place to keep looking.
Confirm It Worked
Test Your WiFi Speed Before and After
The only way to know a change actually helped is to measure it, not to guess from how it feels.
Test your WiFi speed before making any change.
Make one change — router position, band, or anything else from this guide.
Test your WiFi speed again, in the same spot, on the same device.
Compare the two results to see whether that change actually helped.
FAQ
Frequently Asked Questions About WiFi Speed
Short, direct answers to the questions people ask most about improving WiFi speed.
How can I improve my WiFi speed?
Move closer to your router or remove obstacles between you and it, use the 5 GHz or 6 GHz band at short range, reduce interference from other networks and electronics, disconnect devices you are not using, and keep your router’s firmware up to date. See the full list of 12 ways above, and measure the effect with our WiFi Speed Test.
Why is my WiFi so slow?
The most common causes are distance from the router, walls and obstacles, interference from nearby networks, a congested WiFi channel, too many connected devices, an older router or device, or simply a slow underlying Internet plan. See the diagnosis section above to narrow it down.
How can I make my WiFi faster?
Start with the quick fixes at the top of this page — router position, WiFi band and interference make the biggest difference for most people. If those do not help, work through the fuller list of 12 ways, and confirm any change with a before-and-after WiFi Speed Test.
Does moving my router improve WiFi speed?
Often, yes. A central, open location, away from walls, metal and closed cabinets, generally gives every room a stronger, more even signal than a router pushed into a corner. It will not fix a slow Internet plan, but it can meaningfully improve the WiFi leg of the connection.
Is 5 GHz faster than 2.4 GHz?
At short range with a clear line of sight, yes — 5 GHz (and 6 GHz, where supported) typically moves more data than 2.4 GHz. The trade-off is range: 2.4 GHz travels further and passes through walls more easily, so the “faster” band depends on how far you are from the router.
Why is my WiFi slow but my Internet fast?
Your Internet plan describes what your provider delivers to your router; WiFi is a separate, additional step between the router and your device. A wired connection can test fast while WiFi is held back by distance, interference or an older device. Compare a WiFi Speed Test with a wired Internet Speed Test to see the gap.
How can I improve WiFi speed in another room?
Reposition the router toward that room if possible, try the 2.4 GHz band for better range through walls, or add a mesh system or a wired access point if the room is consistently weak. See “How to Improve WiFi in Every Room” above for the full breakdown by situation.
Does restarting the router improve WiFi speed?
Sometimes. Restarting clears temporary memory issues and resets the connection, which can help if performance has degraded over time. It is not a fix for a fundamentally weak signal, an outdated device, or a slow underlying Internet plan.
Can too many devices slow down WiFi?
Yes. Every connected device, active or idle, shares the router’s available capacity and a limited amount of airtime. A large number of active devices, especially several streaming or downloading at once, can noticeably reduce the speed available to each one.
How do I test my WiFi speed?
Connect the device you want to test to your WiFi network, stay in the location you normally use, and run our free WiFi Speed Test. Test before and after any change you make, and compare a few runs rather than judging from a single result.
