Why your internet feels slow when you game

Gaming demands steady, low-delay internet in a way that web browsing does not. When you load a webpage, a few seconds of delay barely matters. When you are playing an online game, even 100 milliseconds of delay — called lag — makes your character move after you press the button, and you will lose firefights or miss jumps because of it. Slow internet shows up as lag, stuttering, or disconnections that do not happen when you are just watching videos.

The problem is usually one of three things: your connection is too slow for gaming, something else on your network is using the bandwidth, or your router is too far away or blocked by walls. The good news is that you can test which one it is and fix most of them yourself in under an hour.

Key Takeaways

  • Gaming needs both speed (at least 5 to 10 megabits per second) and low ping (under 100 milliseconds), and you can measure both with a free speed test.
  • Close other programs and devices using the internet — streaming video, downloads, and video calls will steal bandwidth from your game.
  • Move your gaming device closer to your router or use a wired ethernet cable, which almost always fixes lag caused by distance or walls.
  • If your speed test shows you are getting less than half what your internet plan promises, contact your internet provider to report the problem.
  • Restarting your router clears out stuck connections and often fixes stuttering or lag that appeared suddenly.

Test your internet speed and ping

Before you change anything, measure what you actually have. Go to speedtest.net on any device connected to your home internet. Click the big blue button to start the test. It will measure your read speed (how fast data comes to you) and your ping (how long it takes for a signal to reach the game server and come back).

For gaming, you need at least 5 to 10 megabits per second read speed. Ping matters more than speed — anything under 100 milliseconds is playable, under 50 is good, and under 20 is excellent. If your ping is above 150, you will feel lag in most games. Write down both numbers so you can compare them after you make changes.

Run the test three times at different times of day. If the numbers jump around wildly, something else on your network is using bandwidth right now. If they are consistently low, your internet plan itself may not be fast enough for gaming.

Stop other devices and programs from using the internet

Every device connected to your home network shares the same internet pipe. If someone is streaming Netflix in another room, downloading files, or video calling, your game gets less bandwidth. This is the most common reason gaming feels slow even when your internet plan is fast enough.

Before you game, ask anyone else in your home to pause streaming, pause downloads, and close video calls. On your own device, close web browsers, cloud backup programs, and anything that syncs files — Dropbox, OneDrive, Google Drive, and iCloud all use bandwidth in the background. Check your phone too: if it is connected to your home wifi and updating apps or backing up photos, disconnect it or turn off wifi on it.

After you have closed everything, run the speed test again. If your ping dropped and your speed went up, you found the problem. You do not need to fix your internet — you just need to make sure nothing else is running when you game.

Move closer to your router or use a wired cable

Wifi gets weaker the farther you are from your router, and walls, metal, and water block the signal. If you are gaming in a bedroom three rooms away from your router, or through a thick wall, your connection will be unstable even if your speed test showed good numbers.

The fastest fix is to run an ethernet cable from your router directly to your gaming device. Ethernet is a physical cable that plugs into the back of your router and into your device — it does not rely on wifi at all. If your device does not have an ethernet port (most laptops and phones do not), you can buy a USB adapter for $15 to $30 that adds one. Wired connections almost always have lower ping and more stable speed than wifi.

If you cannot run a cable, move your gaming device as close to the router as you can, ideally in the same room and with a clear line of sight. Even moving from 30 feet away to 10 feet away can cut your ping in half. If your router is in a closet or cabinet, move it to an open shelf or the center of a room — routers broadcast in all directions and work best when they are not enclosed.

Restart your router

Routers sometimes get stuck connections or memory leaks that cause lag or disconnections. Restarting clears these out and often fixes problems that appeared suddenly without any change on your end.

Unplug the power cable from the back of your router and wait 30 seconds. Plug it back in and wait two minutes for it to fully restart — you will see lights on the front stop blinking and settle into a steady pattern. Then run your speed test again. If your ping dropped, the restart fixed it.

If the problem comes back after a few days, restart the router again. If you are restarting more than once a week, your router may be failing and you may need to replace it.

Check your router settings and update its software

Log into your router's settings by opening a web browser and typing 192.168.1.1 or 192.168.0.1 into the address bar. You will be asked for a username and password — if you have not changed them, they are usually "admin" and "admin" or "admin" and the password printed on a sticker on the router itself.

Look for a setting called QoS, Quality of Service, or Traffic Control. This setting lets you tell your router to prioritize gaming traffic over other uses. Turn it on if it is available, and set your gaming device as the highest priority. This will not make your internet faster, but it will make sure your game gets the bandwidth first when other devices are also using the network.

While you are in the settings, check if there is a software update available — routers usually have a System or Administration section that shows this. Updates often fix lag and stability problems. If an update is available, install it and let the router restart.

Contact your internet provider if your speed is too low

If your speed test shows you are getting less than half the speed your internet plan promises — for example, your plan says 100 megabits per second but you are getting 40 — contact your internet provider's customer service. Tell them your speed test results and ask them to check your line.

They may ask you to restart your modem (the device that connects to the wall, separate from your router) or run the test again at a specific time. Sometimes the problem is in their network, not yours, and they can fix it on their end. If the problem persists after they have checked, you may need a technician to visit, or you may need to switch to a faster plan if your current one is not fast enough for gaming.

Frequently Asked Questions

Is ethernet cable really better than wifi for gaming?

Yes. Ethernet has lower ping, more stable speed, and no interference from walls or other devices. If you can run a cable, it will almost always improve your gaming experience. If you cannot, moving closer to your router is the next best thing.

How much internet speed do I actually need to game?

Most online games need 5 to 10 megabits per second. Ping matters more than speed — you can game fine on 5 megabits if your ping is under 100 milliseconds, but 100 megabits with a ping of 200 will feel laggy. Check your game's website for its specific requirements.

Will a new router fix my lag?

Only if your router is old or failing. If your speed test shows good numbers and your ping is low, a new router will not help. If you are restarting your router weekly or your ping is high even when you are close to it, a new router may help.

Can I game on wifi or do I need ethernet?

You can game on wifi, but ethernet is better. If your device does not have an ethernet port, a USB adapter costs $15 to $30 and adds one. If you cannot use ethernet, move as close to your router as possible and make sure nothing else is using the internet while you game.

What should I do if my ping is high even after I have tried everything?

High ping usually means your internet provider's servers are far from the game server, or your connection to your provider is slow. Run your speed test and contact your provider if you are getting less than promised. You can also try a different game server location if your game offers one.
