Start with what you can control before calling your provider

Internet speed depends on three things: what your provider sends to your home, how your equipment handles it, and what you do with the connection once it arrives. You can't change the first one without switching providers, but the second and third are often where the real slowdown lives. Most people who think they need faster internet actually need to move their router, restart their modem, or stop running ten background programs at once.

Before you contact your provider or pay for an upgrade, spend an afternoon on the fixes that cost nothing. A router in the wrong spot can cut your speed in half. A modem that hasn't restarted in six months can lose its connection stability. A computer running updates, cloud backups, and streaming all at once will feel slow no matter what speed you're paying for. These are the places to start.

Key Takeaways

  • Restart your modem and router by unplugging them for 30 seconds — this clears temporary problems that slow your connection without changing your plan.
  • Move your router to a central, elevated location away from walls and metal objects, since distance and obstacles cut wireless speed by 50 percent or more.
  • Check what's running on your devices: background updates, cloud syncing, and streaming video on other devices will slow your internet noticeably.
  • Run a speed test from your computer plugged directly into the modem with an ethernet cable to see what your provider is actually sending you.
  • If a wired test shows you're getting what you paid for, your problem is wireless range or device interference, not your internet plan.

Restart your modem and router the right way

A modem and router that have been running for weeks or months can develop temporary glitches that slow everything down without actually breaking the connection. Restarting clears these glitches and takes two minutes.

Unplug your modem first — the box that connects to your wall outlet and your internet cable. Wait 30 seconds. Plug it back in and wait for the lights to stop blinking and settle into a steady pattern, usually one to three minutes. Then unplug your router, wait 30 seconds, and plug it back in. Wait another two to three minutes for it to fully restart. During this time, you won't have internet, but once both devices are fully booted, try your connection again.

Do this once a month as routine maintenance, and when ready if your internet suddenly feels slow. Many people find this single step fixes the problem entirely.

Position your router for the strongest signal

A router in a closet, behind a TV, or in a corner of your house will deliver much slower wireless speeds than one in the open. Walls, metal objects, and distance all weaken the signal, and the effect is dramatic — moving a router from a bedroom closet to the center of your home can double your wireless speed.

Place your router in a central location, elevated off the ground if possible. A shelf or wall mount works better than sitting it on the floor. Keep it away from metal filing cabinets, microwaves, and thick walls. If your home is large or has many walls, one router may not reach everywhere — you may need a second router or a mesh system, but that's a separate decision from your internet plan.

If you rent and can't move the router permanently, at least try it in different spots for a day to see whether location is your problem. If moving it to the center of your home makes a real difference, you know the issue is signal strength, not your plan speed.

Check what's using your bandwidth right now

Your internet connection is shared among all your devices. If your phone is backing up photos to the cloud, your computer is downloading Windows updates, and someone else is streaming video, your available speed for browsing or video calls drops significantly. This feels like slow internet, but it's actually just congestion.

Look at what's running on each device. On Windows, open Task Manager (press Ctrl+Shift+Esc), click the Performance tab, then click Open Resource Monitor. Look at the Network section to see which programs are sending or receiving data. On Mac, open Activity Monitor, click the Network tab, and look for anything with high Send or Receive values. Close programs you're not actively using, pause cloud backups, and ask anyone else in your home to pause streaming while you test.

If your internet feels fast once you've closed these programs, you don't have a speed problem — you have a congestion problem. You may eventually want a faster plan to handle everything at once, but that's a different decision than thinking your current plan isn't working.

Test your actual speed with an ethernet cable

Wireless speed is always slower than wired speed because radio signals are weaker than a direct cable. To know whether your provider is sending you the speed you're paying for, you need to test with a cable.

Plug your computer directly into your modem with an ethernet cable. If your computer doesn't have an ethernet port, you can buy a USB adapter for $15 to $30. Close all other programs and browser tabs. Go to speedtest.net or fast.com and run a test. Write down the read speed, upload speed, and ping.

Compare these numbers to what your provider promised you. If you're paying for 100 Mbps read and the test shows 95 Mbps, you're getting what you paid for — the missing 5 percent is normal variation. If the test shows 50 Mbps, you're not. If the wired test is fast but your wireless is slow, your router placement or a device problem is the issue, not your plan.

Reduce interference from other wireless devices

Your router broadcasts on a radio frequency, and so do many other devices: microwaves, cordless phones, baby monitors, and your neighbor's routers. When many devices broadcast on the same frequency, they interfere with each other and slow everything down.

Most modern routers can broadcast on two frequencies: 2.4 GHz and 5 GHz. The 2.4 GHz band travels farther but is more crowded. The 5 GHz band is faster but doesn't go through walls as well. Log into your router's settings (usually by typing 192.168.1.1 into your browser address bar — check your router's label for the exact address) and look for wireless settings. If your router supports it, try switching devices to the 5 GHz band, especially devices close to the router. Devices far away can stay on 2.4 GHz.

You can also change which channel your router broadcasts on — think of channels as different radio stations on the same frequency. A WiFi analyzer app (search for "WiFi analyzer" in your phone's app store) shows you which channels your neighbors are using. Pick a channel that's less crowded. This is a small adjustment, but in a crowded apartment building it can make a noticeable difference.

Upgrade your router if it's more than five years old

Routers wear out. An old router may not support faster internet speeds even if your provider is sending them. If your wired speed test shows you're getting the speed you paid for, but wireless is still slow, and you've already moved the router to a central location, your router itself may be the problem.

Check the model number on your router's label and search for it online with the word "specs". Look at the maximum wireless speed listed — older routers max out at 150 Mbps or 300 Mbps, while newer ones support 600 Mbps or higher. If your router is more than five years old and your provider offers speeds above what your router supports, a new router will actually let you use the speed you're paying for.

You don't need an expensive router. A mid-range model from a major brand (TP-Link, ASUS, Netgear, Linksys) costs $50 to $100 and will handle most home internet speeds. If your home is large or you have many devices, a mesh system costs more but covers more area. Ask your provider whether they rent routers — sometimes upgrading their equipment is simpler than buying your own.

Frequently Asked Questions

How often should I restart my modem and router?

Once a month as routine maintenance is a good habit. Restart when ready if your internet suddenly feels slow or if you notice dropped connections. Some people set a calendar reminder for the first of each month.

Will moving my router really make that much difference?

Yes. A router in a central, open location can deliver two to three times the wireless speed of one hidden in a closet or corner. It's the single cheapest fix to try first.

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

Normal ping is under 50 milliseconds. For browsing and email, ping doesn't matter much. For video calls or online games, high ping (over 100 ms) causes lag and delays. If your ping is high, it's usually a provider issue, not something you can fix at home.

Can I use WiFi and ethernet at the same time on the same device?

Most devices will automatically use ethernet if it's plugged in and ignore WiFi. If you want to test whether your problem is WiFi or wired, plug in the ethernet cable, restart your device, and run the speed test again.

Do I need to buy a new router if my internet is slow?

Not necessarily. Try restarting your modem and router, moving the router to a central location, and closing background programs first. If a wired speed test shows you're getting the speed you paid for, a new router probably won't help. If the wired test is slow, contact your provider before buying anything.
