How to Fix a Wi-Fi Connection That Keeps Dropping

Most Wi-Fi troubleshooting goes wrong because people start restarting things before working out which part is broken. There are three separate links in the chain, and each has different symptoms.

Step one: find out which part is failing

Run these checks in order. Each one rules something out.

1. Does the problem affect every device, or one? One device means the fault is on that device. All devices points at the router or the line.
2. Does a wired connection work? If a laptop plugged in with an Ethernet cable is fine while Wi-Fi is not, your internet line is healthy and the problem is Wi-Fi.
3. Does it fail in one room only? That is signal strength or interference, not a broken connection.
4. Do pages fail while the Wi-Fi icon shows full bars? Full bars mean a good link to the router. The fault is past the router, on the internet side.

The distinction between Wi-Fi and internet is explained further in our guide to what Wi-Fi is.

If one device is the problem

• Forget the network and reconnect. This clears a stored configuration that may have gone stale.
• Restart the device. Genuinely worth doing once.
• Check for a driver or system update. On Windows laptops especially, wireless driver bugs are a common cause of repeated drops.
• Turn off battery saving for the wireless adapter. Power management settings often switch off the radio to save energy, which looks exactly like a dropping connection.
• Check whether a VPN or security tool is interfering. Disable it briefly to test.

If every device is affected

Restart properly, in order

Power off the router and the modem. Wait thirty seconds. Power on the modem first and wait for its lights to settle, then the router. Restarting both at once in the wrong order is why this sometimes appears not to work.

Check for an outage

Before spending an hour on settings, check your provider’s status page or app on mobile data. A surprising share of home network problems are faults on the line.

Update the router firmware

Routers run software that is often years out of date. Updates fix stability bugs and security holes. The setting is usually under administration or system in the router’s admin page.

If the problem is signal or range

Move the router

This is the highest value change and it costs nothing. Routers should be central, raised off the floor, and in the open.

Things that block signal badly: metal, water, concrete, mirrors, fish tanks, and the inside of a cupboard. A router on the floor behind a television is in roughly the worst place available.

Change the channel

If neighbouring networks are on the same channel, everyone slows down. On 2.4 GHz only channels 1, 6 and 11 do not overlap, so pick whichever of those is least used nearby. Many routers can scan and choose automatically.

Use the right band

5 GHz is faster but shorter range. If a far room keeps dropping on 5 GHz, letting that device use 2.4 GHz will be slower but far steadier.

Reduce interference

Microwave ovens, cordless phones, baby monitors and some Bluetooth devices all share the 2.4 GHz band. If drops happen at predictable times, look for a device that switches on then.

Consider mesh rather than an extender

A basic repeater receives and retransmits on the same radio, which typically halves throughput. A mesh system with a dedicated link between units avoids most of that loss and hands devices between units cleanly.

Things worth checking that people miss

• Too many devices. Older routers struggle past a couple of dozen connections.
• A neighbour on your network. Check the connected device list and change the password if anything is unfamiliar.
• Overheating. A router in a hot cupboard becomes unstable. Make sure its vents are clear.
• Age. A router more than about five years old may simply be past it.
• Powerline adapters can be a better answer than Wi-Fi for one stubborn room, using your electrical wiring instead of radio.

Frequently asked questions

Why does my Wi-Fi drop at the same time every day?

Something switching on at that time. Common causes are a scheduled backup, a neighbour arriving home and loading the shared channel, or an appliance on the same band.

Does resetting the router delete my settings?

Restarting does not. A factory reset, usually a pinhole button held for several seconds, erases everything including your network name and password. Keep the two separate in your mind.

How many bars do I actually need?

Bars are a rough guide. Two bars with no interference can be more usable than four bars on a congested channel.

Will a new router fix slow internet?

Only if the router is the limit. If a wired test matches your plan speed, the router is fine and the problem is Wi-Fi coverage.

Does the Wi-Fi password affect speed?

The password does not, but the security type can. Very old encryption such as WEP can cap speeds as well as being insecure.

Should I hide my network name?

It provides almost no security benefit and causes connection problems on some devices. A strong password and WPA3 matter far more.
