Start by testing your actual speed

The first step is to measure what you're actually getting, not what you're paying for. Open a speed test site like Speedtest.net, Fast.com, or Google's built-in speed test (search "speed test" in Google). Run it at least twice, a few minutes apart, because one slow result can be a fluke.

Write down the download speed, upload speed, and ping. Download speed is what matters most for streaming and browsing. Upload speed matters if you're on video calls or uploading files. Ping is how fast your connection responds — anything under 50 milliseconds is fine for most things.

Compare your results to what your internet provider promised you. Your bill or your provider's website will show your plan speed. If you're getting 80 percent or more of what you're paying for, your connection is working normally. Internet providers don't may provide you'll hit the exact speed every time.

Key Takeaways

  • Run a speed test on Speedtest.net or Fast.com twice in a row to see your actual download and upload speeds, then compare them to your bill.
  • Slow speeds on one device usually point to that device or your Wi-Fi, while slow speeds on everything point to your internet connection itself.
  • Restart your modem and router by unplugging them for 30 seconds, then plug them back in — this fixes most temporary slowdowns.
  • Check whether your internet provider is having an outage in your area by visiting their website or calling their support line.
  • If your speeds are normal but websites still feel slow, the problem is usually the website's server, not your connection.

Check whether it's your Wi-Fi or your internet connection

Slow internet and slow Wi-Fi are different problems. If only one device is slow, it's almost always Wi-Fi. If everything connected to your network is slow, it's your internet connection.

To test this, plug one device directly into your modem with an ethernet cable and run a speed test. If that device gets normal speeds, your internet connection is fine — your Wi-Fi is the problem. If it's still slow, your internet connection itself is the issue.

If Wi-Fi is the problem, move closer to your router, restart the router, or check whether too many devices are connected and streaming at once. If your internet connection is the problem, move to the next section.

Restart your modem and router

Unplug your modem (the device that connects to your wall outlet and your internet provider's line) and your router (the device that broadcasts Wi-Fi). Wait 30 seconds, then plug the modem back in first. Wait for all its lights to stop blinking and settle into a steady pattern — usually two to three minutes. Then plug in the router and wait for it to finish starting up.

This clears temporary problems that build up over time. Most temporary slowdowns go away after a restart. If your speeds return to normal, you're done. If they're still slow after the restart finishes, move to the next section.

Check for an outage in your area

Your internet provider may be having problems on their end. Visit your provider's website and look for an outage map or status page. Comcast, Verizon, AT&T, and most other large providers have one. You can also call your provider's support line — they can tell you in 30 seconds whether there's an outage affecting your address.

If there's an outage, there's nothing you can do except wait. Your provider usually posts an estimated time for when service will return. If there's no outage, your connection itself may have a problem that needs your provider to fix it.

Contact your internet provider if nothing else works

If your speed test shows you're getting less than 80 percent of your promised speed, your modem and router are restarted, there's no outage, and you've ruled out Wi-Fi problems, call your provider's support line. Have your speed test results ready to show them.

Your provider can run a line test from their end to see whether the problem is in the cable coming to your house or in your modem. They may ask you to restart your modem again while they watch, or they may send a technician. If your modem is old, they might replace it for free.

Understand why websites feel slow even with normal speeds

Sometimes your speed test shows normal speeds, but websites still load slowly. This usually means the website's server is slow or far away, not your connection. You can't fix this — it's the website's problem.

If one specific website is slow but others are fast, the problem is definitely that website. If many websites feel slow but your speed test is normal, try clearing your browser's cache (in your browser settings under Privacy or History) or restarting your device. If that doesn't help, the slowness is on the website's end.

Frequently Asked Questions

Why is my speed test fast but websites still load slowly?

Your internet connection speed and how fast a website loads are different things. A fast connection just means data can travel quickly — it doesn't mean the website's server will send that data fast. If one website is slow but others are fast, that website is the problem. If many websites feel slow, try clearing your browser cache or restarting your device.

What's a normal ping, and does it matter?

Ping is how fast your connection responds, measured in milliseconds. Anything under 50 ms is fine for browsing and streaming. Gaming and video calls work best under 100 ms. If your ping is very high (over 200 ms), you might notice lag, but this is rare unless you're far from your provider's server or have a connection problem.

Does restarting my modem really help?

Yes, but only for temporary problems. Restarting clears memory buildup and resets your connection. It fixes most slowdowns that happen suddenly. If slowness comes back after a few days, the problem is usually something your provider needs to fix, not something a restart will solve permanently.

Should I restart my modem regularly to keep it fast?

You don't need to restart it on a schedule. Restart it only when you notice slowness, or if your provider tells you to. Modems are designed to run continuously. Restarting too often won't help and might actually cause problems if you do it while data is being transferred.

What if my provider says my speeds are normal but I still think they're slow?

Your perception of speed depends on what you're doing. Streaming video needs about 5 Mbps, video calls need 2.5 Mbps, and browsing needs less than 1 Mbps. If you're doing multiple things at once, or if many people are using your Wi-Fi, speeds will feel slower even though your connection is working normally. Check how many devices are connected and what they're doing.
