Before troubleshooting, narrow it down: does it drop on one device or all devices ? Just the device → driver or NIC issue (if the device is an iPhone, jump straight to iPhone WiFi keeps disconnecting ). All devices → router, modem, or ISP.
The most common causes are channel interference from neighbouring networks, an overheating router, outdated firmware, a weak signal at the device, or a dying power supply. Reboot the router, then check signal strength and channel utilisation.
If only one device drops, suspect that device's wireless adapter or driver. Update the WiFi driver, forget and rejoin the network, and disable WiFi power-saving in the OS.
Yes. Routers older than 5-7 years often suffer from capacitor wear, memory leaks and outdated chipsets. If reboots only help temporarily, replace the router.
