Why Does My Wi-Fi Keep Disconnecting? (And How to Fix It)

Few things are more frustrating than Wi-Fi that works perfectly for ten minutes, drops out for thirty seconds, and then comes back like nothing happened. You can't watch a movie, you can't finish a video call, and you start to wonder if it's you, your phone, your router, or your internet company.

Good news: in nine out of ten cases, you can fix this yourself in about ten minutes. Here's how I walk clients through it.

Step 1: Figure out where the problem is

Before you change a single setting, answer this question: does the Wi-Fi drop on every device, or just one?

• Every device drops at once. The problem is your router or your internet provider. Skip to Step 2.
• Only one device drops while everything else stays online. The problem is on that device. Skip to Step 3.

This single question saves you from chasing the wrong fix.

Step 2: If every device is dropping (router-side fixes)

Power cycle the router properly

You probably already tried turning it off and on. Most people do it wrong. The right way:

1. Unplug the router from the wall (not the back of the router, the wall)
2. Wait at least 30 seconds. This matters because the router needs time to clear its short-term memory and let its capacitors fully discharge.
3. If you have a separate modem (the thing your internet provider gave you) and router, unplug both. Plug the modem in first, wait two full minutes for it to come up, then plug the router in.
4. Give the whole thing five minutes before testing.

Check for overheating

Put your hand on the top of the router. If it feels hot, that's your problem. Routers in cabinets, on top of other electronics, or buried in dust drop connections constantly. Move it to a shelf in open air, away from the TV, and clean any dust off the vents.

Move the router higher and more central

Wi-Fi signal goes outward and down, not up. A router on the floor or shoved in a corner gives you weak coverage everywhere. Put it on a shelf around chest height, somewhere central in the house if possible, and away from thick walls or large metal appliances.

Update the router's firmware

Most routers from the last five years can do this with one tap in their app (Netgear Nighthawk, eero, Google Wifi, TP-Link Tether). If your router doesn't have an app, log in by typing 192.168.1.1 or 192.168.0.1 into your web browser and look for "Firmware Update" or "Administration." Outdated firmware causes random drops that no other fix solves.

If your router is older than five years

Most home routers last four to six years before they start dropping connections, overheating, or losing range. If yours is older than five years and the above didn't help, it's almost certainly time for a new one. A modern Wi-Fi 6 or Wi-Fi 6E router is usually the difference between "endless headaches" and "I forgot I had a router." Worth the upgrade.

Step 3: If only one device is dropping (device-side fixes)

On a Windows laptop

This is the most common cause of Wi-Fi drops on a single device, and it has nothing to do with your router. Windows turns off your Wi-Fi adapter to save battery, even when the laptop is plugged into a wall outlet. Turn it off:

1. Right-click the Start button
2. Click Device Manager
3. Expand Network adapters
4. Right-click your Wi-Fi adapter (usually has "Wireless," "Wi-Fi," or "AC" in the name) and pick Properties
5. Go to the Power Management tab
6. Uncheck "Allow the computer to turn off this device to save power"
7. Click OK and restart the laptop

On an iPhone or iPad

Forget the network and rejoin:

1. Open Settings > Wi-Fi
2. Tap the small (i) next to your network
3. Tap Forget This Network
4. Go back, tap your network, type the password, and connect fresh

While you're there, also turn off Private Wi-Fi Address on the same screen. This setting confuses some routers and causes random drops.

On an Android phone

Same idea as iPhone, with a small twist. Open Settings > Connections (or Network & Internet), tap the gear next to your network, choose Forget, then reconnect. Look for a setting called "Use random MAC" or "MAC address type" and switch it to "Use device MAC" instead of random.

On a Mac

Hold Option and click the Wi-Fi icon in the top menu bar. You'll see hidden diagnostic info. If your signal strength (RSSI) is worse than -70 dBm, you're too far from the router. Move closer or upgrade your network. If signal is fine but you're still dropping, go to System Settings > Wi-Fi, click Details next to your network, and turn off Limit IP address tracking.

Why does this happen in the first place?

Wi-Fi drops boil down to five culprits:

1. Your internet provider having unstable service (check their status page or call them)
2. Your router overheating, full of dust, or just too old
3. Your device set up to save power by turning off Wi-Fi
4. Interference from other electronics, neighbors' routers on the same channel, or even big metal objects like fridges and fish tanks
5. Distance and walls reducing your signal below what the device can hold onto

The steps above cover the first three, which together account for most of the Wi-Fi problems I see in real homes.
