Repeated Wi-Fi drops can come from the router, interference, weak coverage, congestion, or one device. Before changing random settings, determine whether the outage affects the whole home and whether a wired connection drops too.
Check whether one device or everything drops
If only one phone or computer disconnects, restart that device, forget and rejoin the network, and update its software. If everything drops together, focus on the router, modem, or internet service.
Separate Wi-Fi failure from internet failure
When a drop occurs, check whether the device remains connected to the local network even though websites stop loading. Testing a wired device helps distinguish wireless failure from an upstream internet outage.
Check coverage and interference
Move close to the router and see whether drops stop. Microwaves, neighboring networks, dense walls, and crowded channels can especially affect 2.4 GHz; a central router location often improves stability.
Frequent router reboots point to a different problem
If the router reboots itself, runs unusually hot, or loses status lights, check power, ventilation, and firmware. Faulty equipment or an unstable provider line may require replacement or service support.
