A laptop may keep disconnecting from Wi-Fi due to several common factors, including weak signal strength, interference from other devices, outdated or faulty network drivers, or incorrect power management settings that disable the wireless adapter to save energy. Router-related issues such as firmware problems, overheating, or network congestion can also contribute, along with incorrect network configurations on the laptop. Identifying whether the issue stems from hardware, software, or the network itself is essential to applying the correct fix and maintaining a stable connection.
