What's actually slowing your connection down

Your internet speed depends on three separate things: your plan's speed from your provider, the condition of the equipment between you and them, and what's using your bandwidth right now. Most people can fix the second and third without calling their provider or paying more. Start by checking what speed you're actually getting, then work through the physical and software fixes that solve most slowdowns.

Run a speed test at speedtest.net or fast.com. Write down the number. This tells you whether you're getting what you're paying for. If the test shows you're getting close to your plan's advertised speed, the problem is usually something using bandwidth or interfering with your signal. If it's much lower, something between your modem and the internet is broken or misconfigured.

Key Takeaways

  • Restart your modem and router by unplugging them for 30 seconds — this fixes the majority of speed problems without any other work.
  • Move your router to a central, elevated location away from walls and metal objects, or switch to a 5 GHz band if your devices support it.
  • Close programs running in the background that use the internet, especially cloud storage, automatic updates, and streaming services.
  • Check how many devices are connected and using bandwidth, since each one shares your total speed.
  • If speed stays low after these steps, contact your provider to check whether your line is damaged or your plan is the problem.

Restart your modem and router the right way

Unplug your modem (the device your provider installed) and your router (the wireless box) from power. Wait 30 seconds. Plug the modem back in first and wait for all its lights to stop blinking and settle into a steady pattern — this usually takes two to three minutes. Then plug in the router and wait another two to three minutes for it to fully start.

This clears out temporary problems that build up over time. Most internet slowdowns disappear after this step alone. If your modem and router are in one device, unplug that single unit and follow the same timing. Do this once a month as routine maintenance, or whenever you notice speed dropping.

Fix your router's location and settings

Your router's signal weakens through walls, metal objects, and distance. Move it to a central location in your home, elevated off the ground — a shelf or wall mount works better than the floor. Keep it away from microwaves, cordless phones, and metal filing cabinets, which interfere with the signal. If your router is currently in a closet or behind a door, moving it to an open area often makes a noticeable difference.

If your router has a 5 GHz band option (check the manual or log into the router's settings), try connecting to that instead of 2.4 GHz. The 5 GHz band is faster but doesn't travel as far, so it works best if you're close to the router. Your device must support 5 GHz — most phones and laptops made in the last five years do. Log into your router by typing 192.168.1.1 into a web browser, then look for wireless settings or band options. If you're not sure how, the router's manual has the exact steps.

Stop programs from using bandwidth in the background

On Windows, open Task Manager by pressing Ctrl+Shift+Esc. Click the Network column to sort by internet use. Close any program you don't recognize or don't need running right now — cloud storage like OneDrive or Google Drive, automatic update services, and streaming apps all use bandwidth constantly in the background. On Mac, open Activity Monitor, click the Network tab, and do the same.

Check your browser too. Too many open tabs, especially video or streaming sites, slow everything down. Close tabs you're not actively using. If you have multiple devices on your network, each one shares your total speed — a phone streaming video in another room uses bandwidth that your work computer could use instead. Ask household members to pause streaming or downloads while you need faster speeds.

Check your actual plan speed and data limits

Log into your provider's website or app and look at your account details. Find your plan's advertised download speed — it's usually listed as something like "100 Mbps" or "1 Gig". Compare it to the speed test result you ran earlier. If your test shows you're getting 80 to 100 percent of that advertised speed, your provider is delivering what they promised and the slowdown is on your end.

Some plans have data caps — a monthly limit after which your speed drops significantly. Check whether your plan has a cap and how much data you've used this month. If you're near or over the limit, that's why speed dropped. The cap resets monthly, but you can also contact your provider about switching to an unlimited plan if this happens regularly.

When to contact your provider

If your speed test shows you're getting much less than your plan promises — say your plan is 100 Mbps but you're getting 20 Mbps — and the problem persists after restarting and closing background programs, contact your provider. Tell them your speed test result and your plan speed. They can check whether your line has damage, whether there's congestion in your area, or whether your modem needs replacement.

Bring your modem's model number (it's on a sticker on the device) when you call. Some providers charge to replace old modems, but if yours is more than five years old, they may replace it free. If your provider says everything looks fine on their end but speed is still slow, the problem may be your router — try borrowing a newer one from a friend to test, or consider replacing yours if it's more than five years old.

Frequently Asked Questions

How often should I restart my modem and router?

Once a month as routine maintenance keeps things running smoothly. If you notice speed dropping suddenly, restart immediately — it fixes most temporary slowdowns. You don't need to restart daily or weekly unless you're having constant problems.

Will a new router make my internet faster?

A new router won't increase your plan's speed, but it can help you use the speed you're paying for. If your router is more than five years old, a newer one may deliver faster speeds to your devices, especially if they support newer wireless standards like Wi-Fi 6.

Why is my speed slower at night than during the day?

Network congestion — more people in your area using the internet at the same time. This is normal and usually temporary. If it happens every night, contact your provider to ask whether your area is experiencing consistent congestion, which may mean you need a faster plan.

Can I speed up my internet by changing my password?

Changing your Wi-Fi password won't speed up your connection, but it does prevent neighbors from connecting to your network and using your bandwidth. If you suspect someone else is connected, change your password and use a strong one with letters, numbers, and symbols.

What's the difference between download and upload speed?

Download speed is what matters for browsing, streaming, and most everyday use. Upload speed matters for video calls, uploading files, and live streaming. Speed tests show both numbers. Most plans have much faster download than upload, which is normal.
