What actually slows down your internet, and what you can fix
Your internet speed depends on three separate things: the speed your provider sends to your home, the path that signal takes through your house, and what is using your bandwidth right now. You cannot change what your provider sends you without calling them or switching providers. But you can almost always improve the other two, and that often matters more than the advertised speed number.
Most people see slower speeds than they pay for because of where their router sits, what is plugged into it, or background programs running on their devices. A router in a closet or basement, a computer downloading updates, or a streaming service running on another device can each cut your speed in half. The good news is that these are free or cheap to fix, and you can test each one yourself.
Key Takeaways
- Move your router to the center of your home, away from walls and metal objects, because distance and obstacles cut wireless speed more than almost anything else.
- Switch to a 5 GHz wireless band if your device supports it, because it is faster over short distances and less crowded than 2.4 GHz.
- Close background programs and streaming services on other devices before you test your speed, because they use bandwidth even when you are not looking at them.
- Restart your modem and router once a month, because they accumulate temporary data that slows down connections over time.
- If speed does not improve after trying these steps, contact your provider to check whether you are getting the speed you are paying for.
Move your router to a better location
The single biggest reason for slow wireless speeds is router placement. A router in a bedroom closet, basement, or behind a TV stand will send a weak signal to the rest of your home. Walls, especially those with metal studs or plumbing, block the signal. Distance cuts speed even more — a device 50 feet away on another floor will be much slower than one 10 feet away in the same room.
Put your router in a central, open location: a hallway, living room, or kitchen counter works well. Elevate it slightly — on a shelf or wall mount rather than on the floor — because the signal spreads better from higher up. Keep it away from metal objects like filing cabinets, refrigerators, and microwave ovens, which interfere with the wireless signal. If you have a two-story home, place the router on the first floor roughly in the middle of the house.
Test your speed before and after moving the router using a speed test website like Speedtest.net or Fast.com. Run the test on the same device from the same location each time so the results are comparable. You should see a noticeable difference within a few feet of the router.
Switch to the 5 GHz wireless band
Most routers broadcast on two wireless bands: 2.4 GHz and 5 GHz. The 2.4 GHz band travels farther and through walls better, but it is slower and more crowded because many devices use it. The 5 GHz band is faster but does not travel as far and does not pass through walls as well. If you are close to your router, 5 GHz will be noticeably faster.
Check what bands your device supports. Older phones and tablets may only work on 2.4 GHz. Computers, newer phones, and tablets usually support both. In your router settings (usually accessed by typing your router's IP address into a web browser, often 192.168.1.1), look for wireless settings and see if you can select which band to use. Some routers let you name the 5 GHz network differently so you can choose it from your device's network list.
Switch to 5 GHz if your device supports it and you are within 30 feet of the router. If you are farther away or the signal is weak, switch back to 2.4 GHz. You can also enable both bands at once and let your device pick the stronger one automatically.
Close programs and services using your bandwidth
While you are testing your speed, other devices and programs on your network are using bandwidth. A computer downloading Windows updates, a phone backing up to the cloud, or a tablet streaming video will all slow down your speed test. Even if you are not actively using them, they are consuming the connection.
Before you test your speed, close all other programs on your device. On Windows, open Task Manager (press Ctrl+Shift+Esc), look at the Network column, and close any program showing high usage. On Mac, open Activity Monitor, click the Network tab, and quit programs using bandwidth. Then tell everyone else in your home to stop streaming, downloading, or gaming for a few minutes while you test.
If your speed is much faster when nothing else is running, but slow when other devices are active, your problem is not your connection — it is that you have too many things using it at once. This is normal in homes with multiple people. If you want faster speeds during peak times, you may need a faster plan from your provider, or you may need to ask others to use bandwidth at different times.
Restart your modem and router
Modems and routers accumulate temporary data and connections over time, which slows them down. Restarting them clears this out and often improves speed noticeably. Do this once a month, or whenever you notice speed dropping.
Unplug your modem (the device that connects to your provider's line) and your router from power. Wait 30 seconds, then plug the modem back in first. Wait for all the lights to stop blinking and stabilize — this usually takes two to three minutes. Then plug in the router and wait for it to fully start up. This is called a "cold restart" and is more effective than using a restart button.
Test your speed after the restart. You should see an improvement, especially if you have not restarted in several months. If speed improves but then drops again after a few days, restart more frequently.
Check your actual speed against what you pay for
Run a speed test on Speedtest.net or Fast.com and write down the results. Compare the read speed to what your provider promises in your contract or on your bill. Most providers promise speeds "up to" a certain number, which means you might not always hit that exact speed, but you should get close most of the time.
If you are getting 50 Mbps when you pay for 100 Mbps, or 10 Mbps when you pay for 25 Mbps, contact your provider. Run the test a few times at different times of day and take screenshots. Providers often have a troubleshooting process: they may ask you to restart your modem, check the signal strength at your house, or send a technician. Do not accept a speed that is consistently 20 percent or more below what you are paying for.
If you are getting the speed you pay for but it still feels slow for what you do, you may need a faster plan. Video streaming needs at least 5 Mbps per stream, online gaming needs at least 10 Mbps, and video calls need at least 2.5 Mbps. If you have multiple people doing these things at once, add them up to see what speed you actually need.
Use a wired connection for devices that need speed
Wireless is convenient but always slower than a wired connection. If you have a desktop computer, gaming console, or streaming device that you use in one place, plug it directly into your router with an ethernet cable. You will see faster, more stable speeds when ready.
Ethernet cables are cheap — a 25-foot cable costs a few dollars at any hardware or electronics store. Run it along the baseboards or under a rug if you need to hide it. If your device does not have an ethernet port (like a laptop or phone), you can buy a USB adapter for $10 to $20 that adds one.
Wired connections are especially helpful for video streaming, large file downloads, or online gaming, where speed and stability matter more than convenience. Keep wireless for phones and tablets that move around your home.
Frequently Asked Questions
Why is my speed slower in some rooms than others?
Walls, distance, and interference from other devices all weaken the wireless signal. Rooms farther from the router, rooms with thick walls or metal studs, and rooms near microwaves or cordless phones will have slower speeds. Moving closer to the router or using a wired connection fixes this.
Does restarting my router really help, or is that just what tech support says?
It really does help. Routers accumulate temporary data and open connections that slow them down over time. A restart clears this out. You should see faster speeds for at least a few days after restarting, though the improvement fades as the router accumulates data again.
What speed do I actually need for streaming and gaming?
Streaming video needs about 5 Mbps per stream, online gaming needs at least 10 Mbps, and video calls need about 2.5 Mbps. If you have multiple people doing these things at once, add them up. Most homes with two or three people doing different things need at least 50 Mbps.
Should I buy a new router if mine is old?
Only if you have tried the steps above and your speed is still much slower than what you pay for. Older routers are slower, but they usually work fine if they are in a good location and restarted regularly. If your router is more than five years old and you have tried everything else, a new one may help.
Can I speed up my internet without calling my provider?
Yes — router placement, restarting, and closing background programs fix most speed problems without contacting anyone. Only call your provider if you are consistently getting less speed than you pay for after trying these steps.
