Why Xiaomi does not see Wi-Fi: all the reasons and ways to fix

Did you turn on Wi-Fi on the Xiaomi Redmi Note 12 or Mi 11 Ultra, but the network doesn't show up in the list - or does the device not respond at all to connection attempts? the problem is found on both new smartphones and Mi Band 7 smartwatches or Mi TVs TV. In 80% of cases, network settings or software failures are to blame, but sometimes it is hardware malfunctions, such as a damaged antenna after a fall.

In this article, we'll look at all the possible reasons Xiaomi doesn't see Wi-Fi, from the banal router that's turned off to the hidden parameters of the developer.
