• 🔌 Indicators burn abnormally: an orange LED flashes, the Wi-Fi indicator does not light up or all the light bulbs burn at the same time.
• 📱 Devices cannot connect to Wi-Fi, although the password is entered correctly (authentication error).
• 🛠️ After updating the firmware router is unstable or some functions are not available.

It is important to distinguish between temporary failures that are solved by a reboot and hardware problems, such as if the router overheats (the body is hot to the touch) or the ports stop working after a thunderstorm. LAN — This is a diagnostic, not a simple rebuke.

⚠️ Note: If the Xiaomi router 4A It reboots itself (cyclically switches on/off), which may indicate a power supply malfunction or firmware damage.

It’s also worth considering that some of the problems are not with the router, but with the provider. For example, if the Internet goes missing on all devices at the same time, including those connected by cable, first check the connection with the operator.

2. Method 1: Soft reboot via web interface
