WiFi Keeps Disconnecting? 12 Fixes That Work
WiFi dropping every few minutes? Work through these fixes for the router, interference and your device, from quickest to deepest.
WiFi that drops every few minutes is one of the most annoying network problems, and it usually has a simple cause: a weak signal, interference, power saving on your device, or a router that needs a restart or update.
WiFi that drops every few minutes usually has a simple cause: a weak signal, interference, power saving, or a router that needs a restart or update. First check if it is one device or every device.
First decide whether the problem is one device or every device. That tells you whether to start with the router or with your phone or laptop. Then work through the fixes below in order.
Quick diagnosis
| What you see | Most likely cause | Start with |
|---|---|---|
| All devices drop at the same time | Router, modem or ISP | Fixes 1 to 5 |
| Only one device drops | Device settings or driver | Fixes 7 to 11 |
| Drops only far from the router | Weak signal | Fix 3 and 6 |
| Drops at certain times of day | Interference or busy channel | Fix 4 |
| Drops after the router was on for days | Router memory or firmware | Fix 1 and 5 |
The same-time drop is the pattern I check first, because it points at the router.
Router fixes (when every device drops)
- Restart the modem and router. Unplug both for 30 seconds, start the modem first, then the router. This clears memory leaks and stuck connections.
- Check the internet light. If it goes red or orange when WiFi drops, the problem is the line or ISP, not WiFi. See router lights meaning.
- Move the router. Put it high, central and in the open, away from metal, fish tanks and microwaves.
- Change the WiFi channel. On 2.4 GHz use 1, 6 or 11. On 5 GHz pick a channel your neighbors are not using, or set it to Auto.
- Update the firmware. Router updates often fix dropouts. See how to update router firmware.
- Split or combine bands. If devices keep jumping between 2.4 and 5 GHz, give each band its own name so devices stay on one.
The 30-second restart is the fix I try before anything else on a dropping network.
Device fixes (when only one device drops)
- Forget the network and reconnect. This clears a corrupted saved profile.
- Turn off power saving for WiFi. On Windows: Device Manager, your WiFi adapter, Power Management, untick “Allow the computer to turn off this device”. On Android, turn off battery optimization for WiFi or Adaptive WiFi.
- Update the WiFi driver or system. Old drivers are a top cause of drops on Windows laptops.
- Turn off private or random MAC for this network if your router uses MAC filtering or reservations.
- Reset network settings. Windows: Settings, Network, Advanced, Network reset. iPhone: Settings, General, Transfer or Reset, Reset Network Settings.
Power saving is the culprit I rule out first when only one device drops.
Less common causes
- Too many devices: older routers struggle with 30 or more devices. A newer router or mesh system helps.
- IP conflict: two devices with the same address knock each other off. Restart the router so DHCP hands out fresh addresses.
- Overheating: a hot router drops connections. Give it airflow.
- Faulty power adapter: a weak adapter causes random reboots. Try a matching replacement.
- Large home: one router cannot cover several floors well. Consider mesh WiFi or an extender.
Overheating is the cause I suspect when drops start after the router has been on for days.
When to replace the router
If your router is more than five years old, only supports WiFi 4 (802.11n), or keeps dropping after a reset and firmware update, a replacement is often the cheapest fix. Our guide on how to choose a WiFi router covers what to look for.
Five years is the age where I stop chasing fixes and start shopping.
