Why Xiaomi smartphone does not catch Wi-Fi: a complete guide to diagnosis and repair

Your Xiaomi Redmi, POCO or Mi suddenly stopped connecting to Wi-Fi, even though other devices are working normally? The problem can be in both phone settings and hardware malfunctions, from lost network settings to a damaged Wi-Fi module. In this article, we will analyze all possible reasons why Xiaomi’s Android smartphone does not catch Wi-Fi, and give step-by-step instructions for troubleshooting – from simple (rebooting the router) to complex (replacing the antenna).

Xiaomi devices feature frequent MIUI updates that sometimes break network settings. For example, after the update to MIUI 14, many users encountered a bug when the phone sees networks but does not connect to them. We took these nuances into account and added current solutions for the latest firmware versions. Also in the article there is a table of compatibility of routers and Xiaomi smartphones, which will help to identify conflicts at the hardware level.

If you've tried to reboot your phone and router before, but the problem is, don't rush to bring your device to service. 80 percent of the time, the malfunction is solved software-based. Let's start with basic checks and gradually move on to deep diagnostics.

Basic checks: router, SIM-map and flight mode

Before digging into your phone's settings, make sure the problem isn't on the router or ISP side. Here's the minimum checklist worth doing first:

  • πŸ”„ Reset the router. Turn it off for 30 seconds, then turn it back on. DHCP Often solves connection problems.
  • πŸ“Ά Check flight mode. Sometimes it's activated randomly (like through the Quick Settings Panel) Open the notification curtain and make sure the airplane icon isn't active.
  • πŸ“± Turn off the mobile Internet. SIM-Deactivate data transfer temporarily, sometimes Android conflicts while using Wi-Fi and 4G.
  • πŸ”Œ Connect another device, see if the Wi-Fi is catching a laptop, tablet or second phone, if not, the router or ISP is having a problem.

If the Wi-Fi was working after this manipulation, it was on the hardware side. If it wasn't, we'll go to the smartphone settings. Some Xiaomi models (e.g. Redmi Note 10 Pro) have a bug where, after restarting the router, the phone does not connect to the network until you reboot it. MAC-address MIUI.
