Why have my Wi-Fi settings disappeared?
Sometimes after updating MIUI, settings sections may be moved or renamed. The missing section may also be related to the region selected during the initial phone setup. Changing the region in Settings β "Advanced" β "Region" to "India" or "Nepal" sometimes restores hidden features, but this may impact the functionality of other services.
Using third-party applications to connect
If direct mode cannot be activated using standard tools, specialized applications come to the rescue. They take control of the network adapter, creating the necessary tunnel for data transfer. Redmi 9 Time-tested utilities are ideal.
One of the market leaders is the application WiFi Direct File TransferIt scans the surrounding area, finds available devices, and initiates a connection. The interface of such programs is usually intuitive: a large button starts the search, and then the target device is selected from the list.
Another popular option is to use file managers with built-in support for the technology, for example, File Commander or Send AnywhereThey use the Wi-Fi Direct protocol to organize transmission, hiding from the user the complex technical details of configuring IP addresses and ports.
| Application | Transmission type | Speed | Peculiarities |
|---|---|---|---|
| WiFi Direct File Transfer | Files, Photos | High | Simple interface, no ads |
| Send Anywhere | Any files | Very high | Works via a 6-digit code |
| SuperBeam | Files, Folders | High | Support for QR codes and NFC |
| XShare | Multimedia | Average | Optimized for Xiaomi devices |
When installing third-party software, carefully monitor the requested permissions. The app requires access to storage, location (to scan Wi-Fi networks), and network settings. Without these permissions, direct connection will not be installed.
