Start with the simplest fixes first

Most slow internet comes from three things you can fix yourself: your router placement, too many devices connected at once, and background programs eating your bandwidth. Before you call your provider or buy new equipment, restart your router, move it to a central location away from walls, and close programs running in the background on your computer. These three steps solve the problem for roughly half the people who think they have a speed issue.

Restart your router by unplugging it for 30 seconds, then plugging it back in. Wait two minutes for it to fully restart — the lights will stop blinking when it is ready. This clears the router's memory and often restores speed that has drifted down over weeks of continuous operation.

Router placement matters more than most people realize. Move your router away from the microwave, away from thick walls, and away from the floor. A central location in your home — ideally on a shelf or table in an open area — reaches more of your space with stronger signal than a router tucked in a corner or closet.

Key Takeaways

  • Restart your router, move it to a central location, and close background programs before assuming you need faster internet from your provider.
  • Check what is actually using your bandwidth by opening your router's admin page or using your device's network settings to see connected devices.
  • Switch to a 5 GHz network band if your router supports it, especially if you are close enough to your router that the signal is strong.
  • Contact your provider to confirm you are getting the speed you are paying for, and ask about free modem upgrades if yours is more than five years old.
  • If your provider's speed is genuinely too slow for your needs, research what other providers serve your address before signing a new contract.

Find out what is actually slowing you down

Before making changes, you need to know whether the problem is your internet connection itself, your router, or something on your device. Run a speed test on your computer while connected by ethernet cable directly to your modem — not through your router. Use a free tool like Speedtest.net or Fast.com. Write down the results.

Now run the same test on the same device connected to your router by Wi-Fi. If the Wi-Fi speed is much lower than the ethernet speed, your router is the bottleneck. If both are similar and both are lower than the speed you pay for, your internet provider is the issue. If both match what you pay for but you still feel slow, something on your device is using bandwidth.

To find bandwidth hogs, open your router's admin page. Most routers use 192.168.1.1 or 192.168.0.1 as the address — type it into your browser's address bar. Log in with the username and password on the back of your router. Look for a section called "Connected Devices" or "DHCP Clients" to see everything connected to your network. Devices downloading large files, streaming video, or running updates will show high data usage.

Reduce interference and switch to a stronger band

Most home routers broadcast on two frequency bands: 2.4 GHz and 5 GHz. The 2.4 GHz band travels farther through walls but is slower and more crowded — microwaves, baby monitors, and your neighbor's router all use it. The 5 GHz band is faster but does not travel as far and works best when you are in the same room as the router.

If you are close to your router, switch to the 5 GHz network. On Windows, go to Settings > Network & Internet > Wi-Fi > Manage Known Networks, find your router's 5 GHz network name (usually the same name with "5G" or "-5" at the end), and connect to it. On Mac, click the Wi-Fi icon in the menu bar and select the 5 GHz version of your network. On phones and tablets, do the same in your Wi-Fi settings.

If you are far from your router and the 5 GHz signal is weak, stay on 2.4 GHz but move your router higher and more central. You can also reduce interference by changing your router's Wi-Fi channel. Log into your router's admin page, find the Wi-Fi settings, and try channels 1, 6, or 11 on 2.4 GHz — these do not overlap with each other. On 5 GHz, most channels do not overlap, so any change usually helps.

Check whether your modem is the problem

Your modem is the device that connects to your provider's network and converts that signal into internet you can use. If it is old, it may not support the speeds your provider now offers. Modems older than five years often cannot handle modern speeds, even if your provider says you are paying for them.

Find your modem's model number on the back or bottom of the device. Search for "[model number] maximum speed" to see what speed it is designed for. If it is lower than the speed you pay for, ask your provider whether they have a free modem upgrade. Many providers will send you a newer modem at no cost if yours is old enough.

If your provider will not upgrade and you want to buy your own modem, check your provider's list of compatible models first — not all modems work with all providers. A newer modem costs between $50 and $150 and can be worth it if you plan to stay with your provider for several years.

Contact your provider to verify your actual speed

Run a speed test again after making the changes above. If the speed is still lower than what you pay for, contact your provider's technical support. Tell them the speed you are getting and the speed you are paying for. Ask them to check the line from their equipment to your home — sometimes the problem is outside your house.

Providers often have free tools to diagnose connection problems. They may ask you to run a test through their own speed test tool rather than a third-party one. Be patient with this process — it usually takes one phone call, but sometimes they need to send a technician to check the line outside your home.

If your provider confirms the line is working correctly but the speed is still too low, ask whether they offer faster plans. If they do not, or if the cost is too high, research what other providers serve your address. You may have options you did not know about.

Upgrade your router if it is old or too far from where you need it

If your modem is fine, your provider's speed is fine, and you have closed background programs, but Wi-Fi is still slow in parts of your home, your router may be too old or too weak for your space. Routers older than five years often cannot handle modern speeds or multiple devices well.

Before buying a new router, measure the distance from your current router to the slowest area of your home. If it is more than 50 feet or through multiple thick walls, a new router with better range may help. Look for routers labeled "Wi-Fi 6" or "Wi-Fi 6E" — these are newer and faster than older "Wi-Fi 5" routers, though they cost more.

If your home is very large or has thick walls, a single router may not reach everywhere. A mesh Wi-Fi system — which uses multiple small units placed around your home — often works better than one powerful router. These cost more but cover larger spaces more evenly.

Know when to accept your provider's limits

Some internet providers in rural areas or older neighborhoods offer only slow speeds, no matter what you do. If you have confirmed that your modem is new, your router is in a good location, and your provider is delivering the speed you pay for, but that speed is still too slow for what you need, you have limited options.

Research whether other providers serve your address — sometimes a cable provider, fiber provider, or fixed wireless provider is available even in areas that seem limited. You can check this on your provider's website or by calling their sales line and giving your address. If no faster option exists, you may need to choose between accepting slower speed or moving to an area with better service.

Frequently Asked Questions

Why is my Wi-Fi fast on my phone but slow on my computer?

Your computer may have a program running in the background that uses a lot of bandwidth. Open your Task Manager on Windows (Ctrl + Shift + Esc) or Activity Monitor on Mac (Command + Space, then type Activity Monitor) and look at the Network column. Close any program using significant bandwidth that you are not actively using.

Does a Wi-Fi extender actually help?

Wi-Fi extenders repeat your existing signal but usually cut your speed in half because they receive and transmit on the same channel. A mesh system is better if you need to cover a large area. If you only need to reach one dead zone, moving your router or using an ethernet cable to a different location usually works better than an extender.

Will paying for faster internet from my provider actually make things faster?

Only if your current speed is lower than what you need and your modem and router can handle the faster speed. If your modem is old or your router is weak, upgrading your plan will not help. Confirm your equipment is modern first, then test whether the faster plan actually reaches you.

Is ethernet cable always faster than Wi-Fi?

Yes, if your modem and router support it. An ethernet cable from your modem or router to your computer removes interference and usually gives you the full speed your provider offers. If you work from home or game online, running an ethernet cable to your desk is the single most reliable way to get consistent speed.

How often should I restart my router?

Restarting once a month is reasonable maintenance. If you notice speed dropping over days or weeks, restart it then. You do not need to restart it daily — that usually means something else is wrong, like a device using too much bandwidth or a modem that is failing.
