Why this helps
Intermittent Wi-Fi issues are usually driver power-save defaults, router band steering, or unstable roaming. Logs show the real cause quickly.
Step-by-step guide
Fix Wi-Fi dropouts
Use log-driven troubleshooting to find power-save and driver issues.
How to verify
A fixed setup should stay connected for several hours without reconnect loops, packet loss spikes, or repeated authentication errors.
Steps
- Collect logs around a disconnect using journalctl.
- Check signal quality and roaming behavior with nmcli.
- Disable aggressive Wi-Fi power-save in NetworkManager.
- If needed, pin to stable band/channel and retest.
