Wi-Fi Keeps Disconnecting Fix

The HP EliteBook 840 G11 drops its Wi-Fi connection every few minutes and reconnects on its own. The Intel Core Ultra 7 155U business laptop pairs with an Intel Wi-Fi adapter, and adapter power management or an outdated driver is the most common reason the link keeps dropping.

If the drops happen only on battery, power management is almost certainly the cause. Disabling it usually fixes the disconnects outright.
