📝 Why Does Wi-Fi Keep Disconnecting? A First Check

Losing Wi-Fi completely and having it drop briefly are different problems. A complete loss usually points at the line or the router. Short drops are nearly always about the wireless link itself — and they are the harder ones to spot, because the signal icon stays full throughout.

Characterise the drops first

Does it happen at the same time each day, or at random? In one room, or everywhere? On one device, or all of them? Those three answers narrow the problem immediately.

If only one device drops, the router is not the issue — look at that device’s wireless adapter and its power settings. If everything drops together, look at the router or the line.

Measure the instability

“It drops sometimes” helps nobody, including your provider. The ping and jitter test measures the stability of the connection; high jitter and sudden spikes show that a link which looks continuous is in fact fluctuating.

Run it in two places: beside the router, and in the room where the problem happens. The difference between the two tells you whether distance or the line itself is responsible. Compare throughput at the same two points with the internet speed test.

The usual causes

• Channel congestion. In apartment buildings dozens of networks share the same channel. Changing it in the router settings can make a clear difference.
• Band steering. If both bands share one network name, devices hop between them and each switch is a brief drop.
• Power saving. Laptops suspend the wireless adapter to save battery. Disable that in power settings.
• Distance and obstacles. A weak signal does not disconnect, but error rates rise, which feels like dropping.
• Microwave ovens. They swamp the 2.4 GHz band while running.

Work through it in order

Power the router off for 30 seconds and back on. If that fixes it and the problem returns days later, suspect router fatigue or overheating — check its ventilation. Next, make the device forget the network and reconnect; a corrupted connection profile causes persistent drops.

If none of that helps, move the router. Height and a position near the centre of the home are the cheapest intervention that reduces drops.

What to tell your provider

Log the dates and times of drops for a week, state whether it also happens on a wired connection, and bring your measurements. If a cable connection never drops, the fault is on the wireless side and there is limited scope for them to help.

Full signal but no internet.
The signal bar shows the link between you and the router, not whether the router has a working connection to the outside.

It drops in the evening but not during the day.
Evening congestion in your area. That points at capacity on the provider’s side.
