Find out which devices lose connection
Compare a phone and computer on the same network at the same time. If both fail, the problem is not necessarily inside the PC. If only one device is affected, record its model and system version. Distinguish Wi-Fi disconnection from a single website or application failing: they require different checks.
Change one test condition
Work closer to the access point and compare another room. Compare separate frequency bands if available. One brief successful test does not prove the fault is gone: repeat the task that triggered it. Note whether disconnection follows sleep, docking or a large transfer.
Drivers and system diagnostics
Windows includes network troubleshooting tools. If problems started after a driver change, record its version. Download drivers for the exact computer or adapter from an official source. Before removing a working driver, prepare a way to restore it and alternative internet access. Random automatic driver utilities can install an unsuitable version.
When is a network reset not the first step?
Resetting can require VPN, virtual adapters or company access to be configured again. Discuss it with the administrator on a work computer. Do not randomly toggle security settings. If reception depends on lid position or worsened after a fall, an antenna or connection fault may be involved.
When should the computer be checked?
If it is unstable on several reliable networks, inspect the adapter, drivers and antennas. Provide test results and disconnection times. Kmvle diagnoses computer problems but does not repair routers. For a network-wide issue, contact the internet provider or network administrator.
Quick checks
| Situation | What to check | What it means |
|---|---|---|
| All devices disconnect | Check the shared network | The issue probably involves more than the computer. |
| Only after sleep | Record adapter and driver version | Software state needs checking. |
| Only in one room | Compare closer to the access point | Signal conditions matter. |
