Mi Box doesn't detect Wi-Fi: What to do if the set-top box can't find a network

You turned on Mi Box, but instead of the usual list of networks, you see a blank screen or the message "No networks available"? Wi-Fi connection issues are one of the most common problems with set-top boxes. Xiaomi, and it can occur on both new and old models (Mi Box S, Mi Box 4, Mi TV Stick). Causes range from simple software glitches to hardware failures, but in 90% of cases, the situation can be fixed independently without calling a service center.

In this article, we'll cover all possible scenarios: from simple checks (such as rebooting the router) to complex firmware manipulations. We'll pay special attention to hidden Android TV settings, which are often ignored in standard instructions but can restore the functionality of your Wi-Fi module. You'll also learn how to distinguish a software glitch from a hardware malfunction—this will help you save time and money.
