The TP-Link Archer BE550 is a Wi-Fi 7 router with 2.5 gigabit ports and a processor that works hard, so a router that restarts on its own or feels very hot is usually suffering from poor ventilation, a power supply problem or a software load that a firmware update can fix. Start with the placement. Routers lose heat through vents, and one pushed into a cabinet, stacked under a modem or placed on a thick cloth runs hot and may reboot to protect itself.
The checks in more detail
Stand it upright in open air with space on every side, away from sun and heaters. Dust in the vents also traps heat, so power it off and blow the vents gently with compressed air held at a distance. Next check the power. Use the adapter that came with the router and plug it firmly into a wall outlet and not a loose extension strip, because an adapter that is failing causes random restarts and drops that look like a router fault. Look at the adapter for heat or a crackling sound, and test with another outlet.
If the lights show a pattern at each restart, note when it happens: if it restarts at the same time each day, a scheduled reboot in the router's settings or a firmware update may be doing it, and TP-Link's Tether app and the web page show the reboot schedule under System Tools. Disable a schedule you did not set, or set it for a quiet time. Software matters as well. Update the router's firmware from the TP-Link support page or from the app, because updates fix stability faults, and check the router's log for a reason.
Reduce load as a test by disconnecting heavy devices, turning off features such as extra VPN servers or aggressive security scanning, and check whether a faulty device on the network is flooding it. If the router restarts when a particular device joins, remove that device. A factory reset, using the reset button for about ten seconds, clears bad settings but erases your setup, so note your settings first. If the router stays too hot to touch and restarts even with a good power supply, clear vents and current firmware, it may be failing, so contact TP-Link with the serial number and ask about warranty.
