One minute the laptop is streaming without a hitch, the next the Wi-Fi symbol has a warning next to it and nothing loads. Then it comes back on its own, and you carry on until the next dropout. Repeated disconnections are one of the most common things people ask about, largely because the fault can sit anywhere between the device in your hand and the line coming into the house. The trick is to work through the checks in a sensible order rather than changing five settings at once and hoping. This walkthrough does exactly that.
First, Decide Whether It Is Wi-Fi or the Broadband Line
Before touching any settings, separate the wireless signal from the internet connection itself. If you have a laptop or desktop you can plug into the router with an Ethernet cable, do that and use it for a while. Two outcomes tell you very different things.
- If the wired connection also drops, the problem is upstream: the line, the router's connection to the internet, or the provider. Wireless tweaks will not help.
- If the wired connection stays rock solid while Wi-Fi keeps falling over, the fault is on the wireless side, either the router's Wi-Fi or the device you are using.
The second question is scope. Does everything drop at once, or is it just one phone, one laptop, or one room? Everything dropping together points at the router or the line. A single device dropping points at that device. One room dropping points at coverage and interference.
Note the Pattern Before You Change Anything
A few minutes spent writing down the pattern saves a lot of trial and error later, and it is genuinely useful if you end up asking someone else for help.
- Which devices disconnect, and is it always the same one?
- When does it happen? Evenings and weekends often hint at congestion from nearby networks or heavy use.
- Where are you sitting when it drops? Distance and walls matter.
- Does it recover by itself, or only after a reboot?
- Has anything changed recently, such as a new router, a new provider, a new appliance, or a new device on the network?
If the honest answer is "it happens constantly, everywhere, on everything", skip ahead to the router and line checks. If it is "only my phone, only in the kitchen", the device and coverage sections will be more useful.
The Usual Suspects Behind Repeated Wi-Fi Dropouts
Most recurring dropouts come back to a short list of causes: signal interference, outdated router hardware, incorrect router placement, network congestion, and problems with the internet provider. Outdated router firmware belongs on that list too, and it is easy to overlook.
Signal interference is what happens when other wireless traffic and even household electronics compete with your network. Placement matters for the same reason: a router tucked into a cupboard, sat on the floor, or pressed against a thick wall is working with one hand behind its back. Network congestion covers both too many devices on your own network and too many neighbouring networks crowded onto the same channels. Outdated firmware can cause disconnecting Wi-Fi issues by preventing the router from properly connecting to the modem, which is why a firmware check is worth doing rather than assuming the box is fine because the lights are on.

A Step-by-Step Fault-Finding Walkthrough
- Power-cycle the router properly. Switch it off at the wall, wait a short while, then switch it back on and give it a few minutes to settle. This clears a temporary glitch and gives you a clean starting point. Do not factory reset it at this stage unless you are sure you have the settings you need.
- Look at where the router sits. Move it out of cupboards and off the floor, keep it away from metal objects and thick walls, and put it somewhere reasonably central if you can. Small moves often produce noticeable improvements.
- Check for interference and congestion. Cordless phones, baby monitors, and other wireless kit nearby can add to the noise. If your router settings let you see which channels neighbouring networks are using, moving your network away from a crowded channel is a standard fix.
- Update the firmware. Log into the router and check for a firmware update, or look for the update options on the manufacturer's own site. Follow their instructions rather than a random forum post, and do it over a wired connection if possible.
- Test the line with your provider's own tools. If the dropouts affect wired devices too, or the router lights suggest the connection itself is going, contact your provider and describe the pattern you wrote down. They can check the line from their end.
- Only then look at the device. If a single device is the only thing dropping, move on to the device-specific checks below.
Symptom, Likely Cause and the First Thing to Try
| What you notice | Most likely area | First check |
|---|---|---|
| Every device drops at the same moment, wired included | Line, provider, or the router's connection to the modem | Contact the provider with your notes and ask them to test the line |
| Wi-Fi drops but a wired device stays connected | Wireless signal, placement, interference, or firmware | Reposition the router, then check for firmware updates |
| Only one room or one corner loses connection | Coverage and interference | Move the router, or look into a mesh or extender setup |
| One device drops while everything else is fine | That device's Wi-Fi adapter or driver | Update the driver and operating system, then retest |

When Only One Device Keeps Dropping
If the rest of the house is fine and one phone or laptop keeps losing the network, the problem is on that device. Common culprits are an out-of-date Wi-Fi driver, a pending Windows update, a power-saving setting that switches the adapter off, or a saved network profile that has become muddled.
Change one thing at a time and test properly afterwards. A good example of why this matters comes from a Microsoft Q&A thread where a user had updated the Wi-Fi driver using the manufacturer's site and still found themselves getting disconnected. That does not mean driver updates are pointless. It means a driver update is one variable, and if you update the driver, install Windows updates, and change three settings in the same afternoon, you will never know which one helped or which one made it worse.
New Line or New Provider? Give It a Few Days
If you have just had a new line or service installed, occasional dropouts in the first three days can be normal. The provider's system needs time to update the new line and settle on the best speed for it. Reset the router during that window and you can interrupt the process and make things worse. Make a note of the dropouts instead, and if they continue past the settling period, raise it with your provider.
Router Age, Firmware and the Limits of an Old Box
Routers do not last forever, and hardware that was fine five years ago may struggle with the number of devices now connected in a typical home. If you have already checked placement, interference, firmware and the line, and the dropouts carry on across every device, an ageing router is a reasonable thing to suspect. Before replacing anything, check the manufacturer's support pages for your model so you are not comparing a working router against a new one for no reason.

When to Stop and Ask for Help
Some of this is straightforward once you know the order to do it in. Some of it is not, particularly when the fault sits in router settings, mesh systems, or a device that will not behave. If you have been round the loop more than once and the dropouts are still there, it is usually quicker to have someone look at it properly.
FixPoint IT Support covers home computer repair and small-business IT across Basildon and the surrounding Essex area, including Wi-Fi and home network help for dropouts, dead zones, router and mesh setup, and printer connection problems. Work is carried out on a no fix, no fee basis with the price agreed upfront before any chargeable work begins, and rates start from £45. If you would rather not spend another evening rebooting a router, that is a reasonable call to make.
Frequently Asked Questions
Why does my Wi-Fi drop on my phone but not my laptop?
When one device drops and others stay connected, the fault is almost always on that device rather than the network. Check for operating system and app updates, update the Wi-Fi driver if the device allows it, and remove the saved network before reconnecting. If your phone still disconnects while everything else is stable, the router is probably not the problem.
Can old router firmware really cause dropouts?
Yes. Outdated firmware can cause disconnecting Wi-Fi issues and can prevent the router from properly connecting to the modem. Check for updates through the router's own admin pages or the manufacturer's site, and follow their instructions exactly. Do the update over a wired connection where possible so a dropout mid-update does not leave you with a half-finished router.
Should I reset my router if my internet keeps dropping?
A simple power cycle, switching it off and back on, is safe and often clears a temporary glitch. A full factory reset is different and should be a last resort, because it wipes your settings. If you have just had a new line installed, avoid resetting anything in the first three days while the provider's system settles your connection.
How do I know if my router is on its way out?
Repeated dropouts across every device, wired connections failing at the same time, and a router that only behaves after a restart are all reasons to look more closely. Check placement, interference, firmware and the line first, then check the manufacturer's support pages for your model before assuming the hardware has failed.
Does a slow connection mean the same thing as a dropping one?
Not quite. Dropouts mean the connection stops altogether, while slowness means it keeps working but at a lower speed. They can share causes such as congestion, interference or a tired router, so run through the same checks. If the connection is stable but slow, start with the router's position and how many devices are using it.
