Router Keeps Disconnecting, Wi-Fi Drops and Reconnects
Wi-Fi that drops and reconnects is usually not a broken router. It is most often interference, a weak signal in one spot, too many devices, or a router struggling under load. The key question is whether every device drops at once, or just one device in one place.
The fix, in order
Find the scope. If every device drops at the same time, the router or the internet line is the problem. If only one device drops, the problem is that device or its distance from the router. If only one room is affected, the signal is too weak there.
Restart the router and modem. Unplug both for 60 seconds, plug the modem back in first, wait for its lights to settle, then plug the router back in. This clears temporary glitches that cause drops.
Move the router. Put it in a central, open spot, up high, away from thick walls, metal objects, mirrors, microwaves, and baby monitors. A router hidden in a cabinet or behind a TV drops far more often than one in the open.
Split or switch bands. The 5 GHz band is faster but shorter range, and drops first through walls. The 2.4 GHz band reaches further. If a device keeps dropping on 5 GHz, try the 2.4 GHz network for that device.
Change the Wi-Fi channel. Neighbors' networks on the same channel cause interference. In the admin page, set the 2.4 GHz channel to 1, 6, or 11, whichever is least crowded, and let the 5 GHz band choose its channel automatically if that option exists. The Wi-Fi channel planner can help you find the least crowded channel.
Update the firmware and reduce the load. Old firmware can drop connections, and an old router can run out of capacity with many devices connected. Disconnect devices you no longer use and update the firmware over a wired connection.
Do not factory reset the router as a first step for dropping Wi-Fi. A reset erases your settings and rarely fixes interference or placement problems, which are the usual causes.
If it still happens
If the drops continue after moving the router, changing channels, and updating the firmware, test with a wired connection. If wired devices stay connected while Wi-Fi drops, the wireless radio or the router's placement is the problem, and a mesh system or a wired access point may be the real fix. If wired devices drop too, the line or modem is the suspect, contact your provider through its official support channel.
Common questions
Why does my Wi-Fi disconnect when I move to another room? The signal is too weak there. Walls, floors, and distance weaken Wi-Fi, and the 5 GHz band fades fastest. Moving the router to a more central spot, or adding a mesh node or access point, is the fix.
Why does Wi-Fi drop only in the evening? Evening is when neighbors are all online, so interference peaks, and when your own household is streaming and gaming hardest. Try a less crowded channel and check whether the router is overheating under the load.
Can too many devices make Wi-Fi disconnect? Yes. Older routers struggle once dozens of devices are connected, especially smart home gadgets that stay connected all day. Disconnect what you do not use, and consider a newer router if the count keeps growing.
