How to know whether your internet is slow right now

Your internet feels slow, but you need to know whether the problem is your connection, your devices, the websites you're visiting, or your internet provider's network. The fastest way to find out is to run a speed test — a tool that measures how fast data moves between your device and a test server — and compare the result to the speed your provider promised you.

Open a browser and go to speedtest.net or fast.com. Both are free and take about a minute. Write down the download speed (measured in Mbps, or megabits per second) and upload speed. Then check your internet bill or log into your provider's website to find the speed tier you're paying for. If your test result is significantly lower — usually 25% or more below what you're paying for — your provider's network may be the problem. If the speed test shows normal speeds but websites still load slowly, the problem is somewhere else.

Key Takeaways

  • Run a speed test at speedtest.net or fast.com and compare the result to the speed tier listed on your internet bill.
  • Slow speeds during peak hours (typically 7 p.m. to 11 p.m.) usually mean your provider's network is congested, not broken.
  • If speed tests show normal speeds but websites load slowly, restart your router, check for background downloads, or test a different website before calling your provider.
  • Restarting your router by unplugging it for 30 seconds often fixes temporary slowness caused by memory buildup or connection drops.
  • If your speed test is consistently 25% or more below your plan speed, contact your provider to report the issue and ask them to check your line.

Check the time and your provider's network status

Internet speed varies throughout the day. Between 7 p.m. and 11 p.m., when most people are streaming video and using the internet at home, your provider's network gets congested. Your connection may slow down even though nothing is broken. This is especially common if you live in a densely populated area or share your network with many neighbors on the same provider.

Before you assume there's a problem, check your provider's status page. Comcast (Xfinity) has a status tool at xfinity.com/support/status. Verizon Fios users can check fios.verizon.com/support/status. AT&T has a similar page at att.com/support. These pages show outages and known issues in your area. If there's an active outage, your provider already knows about it and is working on it — calling won't speed things up.

Restart your router and check for background activity

Routers accumulate temporary data in memory over time, which can slow your connection. Unplug your router from power for 30 seconds, then plug it back in. Wait two to three minutes for it to fully restart. This simple step fixes slowness about half the time because it clears the router's memory and forces it to reconnect to your provider's network.

While your router restarts, check what's running on your devices. Open your Task Manager (Windows: press Ctrl+Shift+Esc; Mac: press Command+Space, type Activity Monitor, press Enter) and look at the Network column. If something is using a lot of bandwidth — a Windows update, a cloud backup, a large download — pause it and run your speed test again. Background activity can make your internet feel slow even though your connection speed is fine.

Test from different devices and websites

Slowness on one device doesn't always mean your internet is slow. Try opening a different website on a different device. If YouTube loads quickly on your phone but slowly on your laptop, the problem is probably your laptop — maybe it has malware, a browser extension that's misbehaving, or too many browser tabs open. If YouTube is slow on both devices, your internet connection is likely the problem.

Also test a website that's geographically close to you. If you're in the United States, a website hosted in Europe will naturally be slower than one hosted in the U.S. because data has to travel farther. Try visiting google.com or amazon.com — both have servers worldwide and usually load quickly. If those sites are slow, your internet is slow. If they're fast but a specific site is slow, that site's server may be overloaded or far away.

Move closer to your router or switch to a wired connection

Wi-Fi signal weakens with distance and through walls. If you're far from your router or separated by multiple walls, move closer and run another speed test. If the speed improves significantly, your Wi-Fi signal is the problem, not your internet connection. You can fix this by moving your router to a more central location, away from microwaves and cordless phones, or by buying a Wi-Fi extender or mesh system.

For the most accurate speed test, connect your device directly to your router with an ethernet cable. Ethernet bypasses Wi-Fi entirely and shows your true connection speed. If the ethernet speed is normal but Wi-Fi is slow, you know the issue is your wireless network, not your provider. If both are slow, contact your provider.

Contact your provider if speeds stay low

If your speed test consistently shows 25% or more below your plan speed, and you've restarted your router and ruled out background activity, contact your provider. Have your speed test result ready. Most providers will ask you to run another test while you're on the phone, or they'll run a test from their end. They may also check the signal strength on your line — a weak signal can cause slowness even if your router is working correctly.

If your provider finds a problem, they may send a technician to check your modem, router, or the line coming into your house. If they don't find a problem but your speeds are still low, ask whether you're in a congested area or whether your plan speed is realistic for your neighborhood. Some providers oversell capacity in certain areas, which means speeds drop during peak hours even though nothing is technically broken.

Understand the difference between speed and performance

A speed test measures raw data transfer rate, but it doesn't measure everything that affects how fast the internet feels. Latency — the time it takes for a signal to travel from your device to a server and back — matters for video calls, online games, and real-time applications. Jitter — variation in latency — can make video calls choppy even if your download speed is high. Packet loss — data that gets lost and has to be resent — can cause buffering and slowness.

Speed tests show download and upload speed, and usually latency as well (look for a number in milliseconds, or ms). For everyday browsing, download speeds above 25 Mbps are usually fine. For video streaming, 5 to 10 Mbps per stream is typical. For gaming or video calls, latency below 100 ms is good; above 150 ms and you'll notice lag. If your speed test shows good speeds but latency is high or unstable, that's a separate problem worth reporting to your provider.

Frequently Asked Questions

Why is my internet slow only at certain times of day?

Network congestion. Your provider's infrastructure can only handle so much traffic at once. During peak hours — typically evenings and weekends — many people are using the internet simultaneously, and speeds drop for everyone. This is normal and not a sign of a problem. If speeds are normal during off-peak hours, congestion is the cause.

Can a VPN make my internet slower?

Yes. A VPN encrypts your traffic and routes it through another server, which adds a small delay and uses some bandwidth. The slowdown is usually 5 to 15%, but it can be more if the VPN server is far away or overloaded. If you suspect your VPN is the problem, disconnect it and run a speed test again.

What's a normal internet speed?

It depends on what you do. For email and browsing, 5 to 10 Mbps is fine. For streaming video, 5 to 10 Mbps per stream. For multiple people streaming at once, 25 to 50 Mbps. For gaming or video calls, you need low latency more than high speed — anything above 25 Mbps is usually enough, as long as latency is below 100 ms.

Should I restart my router every day?

No, but restarting it once a month or when you notice slowness is reasonable. Routers are designed to run continuously, but they do accumulate temporary data over time. If you notice slowness regularly, restarting weekly might help. If speeds are consistently normal, you don't need to restart at all.

What if my speed test shows fast speeds but everything still feels slow?

Check latency in your speed test result — it's usually shown in milliseconds. High latency (above 150 ms) can make the internet feel sluggish even with fast speeds. Also check whether a specific application is using bandwidth — a Windows update or cloud backup running in the background can make everything feel slow. If latency is normal and nothing is downloading, the slow website or service itself may be the problem.
