A Wi-Fi connection that comes and goes is usually a sign of interference, signal strength, or router placement, rather than a problem with your broadband line itself.
Start by checking whether the drop-outs are happening on one device or all of them. If it's just one device, the problem is usually with that device's Wi-Fi card or drivers, not your network. Try forgetting the network on that device and reconnecting, or restarting it.
If multiple devices are dropping, the most likely culprits are:
The router being tucked away in a cupboard, behind a TV, or on the floor. Routers work best out in the open, at about waist height, away from walls and large metal objects.
Interference from other electronics. Microwaves are the biggest offender, but baby monitors, cordless phones, and Bluetooth speakers can all cause issues.
Too many neighbouring Wi-Fi networks on the same channel. Most routers will pick a channel automatically, but restarting your router prompts it to choose again, which often clears congestion.
An overloaded network. If you have lots of smart home devices, streaming sticks, and phones all on Wi-Fi at once, the router can struggle to keep up.
If the drop-outs are happening at certain times of day, or in specific rooms, that's a useful clue to share with us if you need to report a fault.
