A systematic approach to finding why your connection keeps dropping — from driver bugs to router channel conflicts.
Connect another device to the same Wi-Fi. If it also drops, the problem is the router or ISP — not your PC. Power-cycle the router (off 30 sec, on). If only your PC drops, continue.
Device Manager → Network Adapters → right-click your Wi-Fi adapter → Update driver. If the issue started after a recent Windows Update, try 'Roll back driver' instead.
Device Manager → Wi-Fi adapter → Properties → Power Management → uncheck 'Allow the computer to turn off this device to save power'. This is the most common cause of random drops on laptops.
Download Wi-Fi Analyzer (Microsoft Store, free). Scan your area. If your router's channel (1, 6, or 11 for 2.4 GHz) is crowded with neighbours, log into your router admin (typically 192.168.0.1) and switch to the least congested channel.
If your router is dual-band, connect to the 5 GHz network. It has shorter range but far less interference. If drops stop, your 2.4 GHz environment is the culprit.
Open Command Prompt as Administrator. Run: netsh winsock reset, then netsh int ip reset, then ipconfig /flushdns. Restart. This resolves many ghost-drop issues caused by stale network config.
