Start with what's actually slowing you down

Before you buy new equipment or call your provider, find out whether the problem is your connection itself or something using up the bandwidth you already have. Run a speed test on the device that feels slow, then run the same test on a different device in the same room. If one device is much slower, the issue is usually that device — too many browser tabs open, a background app downloading, or malware. If all devices are slow, the problem is your connection or your router.

The next step is to check what's actually connected to your network. Log into your router's admin panel (usually 192.168.1.1 or 192.168.0.1 in your browser address bar — check your router's label for the exact address) and look at the list of connected devices. Unfamiliar devices mean someone else is using your Wi-Fi. If you see devices you recognize but don't use — a phone you replaced, a smart TV in another room — disconnect them.

Key Takeaways

  • Restart your modem and router by unplugging them for 30 seconds, then plugging them back in — this fixes most speed problems and costs nothing.
  • Move your router to a central, elevated location away from walls, metal objects, and other electronics, since physical obstacles slow Wi-Fi more than distance does.
  • Switch to the 5 GHz Wi-Fi band if your router supports it and your devices are within 30 feet, because it's faster than 2.4 GHz but doesn't travel through walls as well.
  • Check whether your internet plan's speed matches what you're paying for by contacting your provider, since you may be on an outdated plan or experiencing a service issue.
  • If nothing improves your speed and your provider confirms the connection is working correctly, your plan may straightforward be too slow for your household's needs.

Restart your modem and router the right way

This fixes roughly half of all speed problems. Unplug your modem (the device that connects to your wall outlet and your provider's network) and wait 30 seconds. Plug it back in and wait for all the lights to stop blinking and settle into a steady pattern — usually two to three minutes. Then do the same with your router (the device that broadcasts Wi-Fi). This clears out temporary memory problems that slow down data flow.

Do this once a month as routine maintenance, or whenever you notice speed dropping. If speed improves for a few days then drops again, your equipment may be overheating. Make sure both devices have space around them — not in a closet, not under a blanket, not stacked on top of each other.

Position your router for better Wi-Fi reach

Wi-Fi travels in straight lines and bounces off hard surfaces, so placement matters more than most people think. Put your router in a central location in your home, elevated off the ground — on a shelf or mounted on a wall rather than on the floor. Avoid placing it inside cabinets, behind the TV, or near a microwave, cordless phone, or baby monitor, all of which broadcast on similar frequencies and cause interference.

Walls, especially those with metal pipes or insulation, block Wi-Fi. If your router is in one corner of your home and you're trying to use Wi-Fi in the opposite corner, you're fighting physics. If you can't move the router to a more central spot, a Wi-Fi extender or mesh system can help, though both cost money and add complexity. Start by moving the router first — it's free.

Switch Wi-Fi bands if your router supports it

Most modern routers broadcast on two frequencies: 2.4 GHz and 5 GHz. The 2.4 GHz band travels farther and through walls better, but it's slower and more crowded — your neighbors' Wi-Fi networks also use it. The 5 GHz band is faster but doesn't travel as far and doesn't go through walls well.

If your device is close to your router (within 30 feet, in the same room or one room over), switch to 5 GHz and you'll usually see faster speeds. Log into your router's admin panel, find the Wi-Fi settings, and look for a network name ending in "-5G" or labeled as 5 GHz. Connect your device to that network instead of the 2.4 GHz one. If you don't see a 5 GHz option, your router doesn't support it.

Check whether your internet plan matches your speed

Your provider sells you a specific speed — often 100 Mbps, 300 Mbps, or 1 Gbps. If you're paying for 100 Mbps but only getting 50 Mbps, either your plan is wrong or something is broken. Call your provider's customer service line and tell them you're getting slower speeds than you're paying for. They can run a line test from their end to see if the problem is on their network or yours.

While you're on the phone, ask what speed tier you're actually subscribed to. Many people discover they're on an old plan from years ago that's slower than what's now available at the same price. Providers don't usually upgrade you automatically — you have to ask. If your provider confirms your connection is working at the speed you're paying for, the issue is that your plan is too slow for what you're doing.

Understand what speed you actually need

Different activities use different amounts of bandwidth. One person browsing the web uses about 5 Mbps. One person video calling uses about 2.5 Mbps. One person streaming video in HD uses about 5 Mbps. If four people in your home are all doing these things at once, you need at least 20 Mbps. If two people are streaming 4K video simultaneously, you need 50 Mbps or more.

Most providers' entry-level plans (50 to 100 Mbps) work fine for one or two people. Households with three or more people, or anyone who works from home on video calls, usually need 200 Mbps or higher. Gaming and large file downloads use less bandwidth than you'd think — the real bottleneck is usually video streaming.

When to upgrade your equipment

If you've restarted your router, repositioned it, switched Wi-Fi bands, and confirmed your plan speed is correct, but you're still getting slow speeds on devices close to the router, your equipment may be old. Routers last about five to seven years before they slow down. If your router is older than that, or if it only has one Wi-Fi band (2.4 GHz only), replacing it will likely help.

Before you buy a new router, check whether your modem is also old. Some internet providers rent modems to you monthly — if you've been renting the same modem for five years, upgrading to a newer model (or buying your own) can improve speed. Ask your provider which modems work with your plan. A new modem costs $50 to $150 one time, while renting costs $10 to $15 per month.

Frequently Asked Questions

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

Your phone and laptop may be on different Wi-Fi bands — your phone might be on 5 GHz (faster, shorter range) while your laptop is on 2.4 GHz (slower, longer range). Check which network each device is connected to in its Wi-Fi settings. You can also manually disconnect from 2.4 GHz in your laptop's settings so it only connects to 5 GHz when available.

Does changing my Wi-Fi password make it faster?

No, but it stops other people from using your network, which makes it faster. If your speed improves after you change your password, it means someone was connected to your Wi-Fi. Change your password through your router's admin panel to something long and random — at least 12 characters with numbers and symbols.

Will a Wi-Fi extender fix my slow speeds?

A Wi-Fi extender can help if you're far from your router and getting weak signal, but it won't make your overall connection faster — it just spreads the same speed over a larger area. If your speeds are slow everywhere, an extender won't help. If speeds are fine near the router but drop far away, an extender or mesh system may be worth trying.

How often should I restart my modem and router?

Once a month is a good routine. If you notice speed dropping suddenly, restart both devices when ready. If you have to restart more than once a week to get normal speeds back, contact your provider — something may be wrong with your connection.

What's the difference between my modem and my router?

Your modem connects to your provider's network and converts that signal into data your devices can use. Your router takes that data and broadcasts it as Wi-Fi. Some devices combine both into one unit, but they're usually separate. Your modem has one cable going to the wall outlet; your router plugs into the modem.
