How to Speed Up Slow Wi-Fi at Home

Quick answer

Slow Wi-Fi at home is most often caused by distance and obstacles between your device and the router, too many devices sharing the connection, or an internet plan that is slower than you need. Start by restarting the router, moving it to a central, open spot, and connecting nearby devices to the faster 5 GHz band if your router offers one. This guide is for anyone whose video calls stutter, streams buffer or downloads crawl at home.

Before you start

First, find out what “slow” really means in your home. Picture a home office in a back bedroom: video calls freeze there, but work fine in the kitchen next to the router. That is a coverage problem, not an internet problem.

• Restart the router. Unplug the router (and the modem, if separate), wait about 30 seconds, and plug it back in. Give it a few minutes to start.
• Run a speed test in two places. Use your internet provider’s speed test or another well-known one. Test once right next to the router and once where things feel slow.
• Compare with your plan. If speeds next to the router are close to what your plan promises, your Wi-Fi coverage is the issue. If they are low even next to the router, the plan or the service may be the issue.
• Try a cable if you can. A laptop connected with an Ethernet cable shows the best speed your connection can give, without Wi-Fi in the way.
• Rule out the computer itself. If only one older laptop feels slow at everything, not just online, see our guide to a slow computer.

Improve your Wi-Fi signal

Wi-Fi is a radio signal. Walls, floors, metal and water (including fish tanks) all weaken it, and so does distance. These steps improve coverage without buying anything.

1. Move the router to a central, open spot. Put it up high, such as on a shelf, rather than on the floor, inside a cabinet or behind the TV.
2. Keep it away from interference. Microwaves, cordless phone bases, baby monitors and thick metal objects can disturb Wi-Fi. Give the router some space.
3. Point the antennas sensibly. If your router has adjustable antennas, try setting some upright and some sideways. Small changes can help in multi-story homes.
4. Choose the right band. Many routers broadcast on two bands. 2.4 GHz reaches farther and passes through walls better but is slower and more crowded. 5 GHz is faster but has shorter range. Use 5 GHz for devices in the same or next room, and 2.4 GHz for devices far away. Some routers combine both under one name and choose for you.
5. Update the router. Routers get firmware updates (built-in software updates) that can fix bugs and improve speed. Many routers can update automatically through their app. Router admin pages and apps differ by brand, so follow your router maker’s or internet provider’s instructions.
6. Update your devices. On Windows 11, install updates from Settings, then Windows Update, which can include newer Wi-Fi drivers (the small programs that let Windows use the Wi-Fi hardware). On a Mac, use System Settings, then General, then Software Update.

Find what is using your connection

Everyone in the home shares the same internet connection. A single large download or several 4K video streams can slow everything else.

1. Pause big downloads and updates. Game downloads, cloud backups and system updates can use a lot of bandwidth (the amount of data your connection can carry at once). Schedule them for overnight if you can.
2. Check what is running on your computer. On Windows 11, open Task Manager (press Ctrl+Shift+Esc) and look at the Network column on the Processes page. On a Mac, open Activity Monitor and click the Network tab. Close apps you don’t need.
3. Count your devices. Phones, TVs, smart speakers, cameras and game consoles all share the connection. Turn off or disconnect devices you are not using.
4. Look for devices you don’t recognize. Your router’s app or admin page usually lists connected devices. If you see unfamiliar ones, change your Wi-Fi password and make sure security is set to WPA2 or WPA3. Don’t share the new password beyond your household, and never give it to someone who calls or messages you unexpectedly.

Test on Windows 11 and Mac

On Windows 11, open Settings, then Network & internet, then Wi-Fi, and select your network’s properties to see which band you are on (it appears as “Network band” in most versions). On a Mac, hold the Option key and click the Wi-Fi icon in the menu bar to see details such as the channel and band. Mac users can also run Wireless Diagnostics from that same menu for suggestions.

If this does not work

Try these next steps, easiest first:

• Use a wired connection for key devices. A desktop PC, TV or game console near the router is often better on an Ethernet cable.
• Add coverage. In larger homes, a mesh Wi-Fi system (several units that work together to cover the house) or a well-placed extender can help far-away rooms. Buy from a reputable retailer and set it up with the maker’s official app.
• Ask your provider about your equipment. Older routers may not support newer, faster Wi-Fi standards. Your provider can tell you whether your equipment is current.
• Review your plan. If even wired speeds are slow at busy times, a faster plan or a line check may be needed.
• Check a specific problem. If your Wi-Fi shows connected but pages don’t load at all, see Connected to Wi-Fi but no internet. For more networking help, browse the Wi-Fi and networking guides.

Be careful with apps or browser extensions that claim to “boost” Wi-Fi or internet speed. They can’t change how your router or service works, and some are adware or worse.

When to get professional help

Contact your internet provider, the router maker, or a qualified technician if:

• Speeds are slow even with a cable plugged straight into the router, after a restart.
• The connection drops many times a day or the modem shows fault lights.
• The router or modem is very hot, makes noises, smells burnt or has a damaged power adapter. Unplug it and stop using it.
• You need cables run through walls for wired connections. Leave that to a qualified installer.

Contact your provider using the details on your bill or official website. Be wary of anyone who calls you first offering to “fix” slow internet with remote access or a payment.

FAQ

Why is my Wi-Fi slow in only one room?

That room is probably too far from the router or behind walls that block the signal. Try moving the router closer to the middle of the home. If that is not possible, a mesh system or extender can help.

Should I use 2.4 GHz or 5 GHz?

Use 5 GHz when you are close to the router for faster speeds. Use 2.4 GHz for devices that are far away or behind several walls. Some older devices and many smart-home gadgets only support 2.4 GHz.

Does restarting my router really help?

Often, yes. A restart clears temporary problems and may let the router pick a less crowded channel when it starts up. It is a quick first step, though it won’t fix poor router placement or an overloaded plan.

Can neighbors slow down my Wi-Fi?

Nearby networks on the same channels can cause some interference, especially on 2.4 GHz in apartment buildings. If someone is using your network without permission, change your Wi-Fi password and use WPA2 or WPA3 security.

Do Wi-Fi booster apps work?

No. Apps that promise to boost Wi-Fi can’t change your router or your internet service. Real improvements come from better router placement, updates, wired connections, or better equipment.
