You try to stream a Xiaomi smartphone screen to a TV via Wi-Fi Direct or Miracast, but the devices stubbornly “cannot see” each other – despite being connected to the same network? This problem is familiar to many owners of Redmi, POCO or Mi phones, especially when working with Samsung, LG or even Xiaomi Mi TVs. 80% of the time, the fault is at the level of network protocols, not “broken iron”.
In this article, we’ll look at 7 key reasons why Xiaomi doesn’t detect a TV on the local network, from simpler router setting errors to firmware version conflicts. You’ll get step-by-step instructions with screenshots (for current versions of MIUI 14/15 and Android 13/14), a table of device compatibility and answers to frequent questions. And if you’ve tried everything, at the end there’s a section with non-obvious solutions that work even when “nothing helps.”
1. Basic conditions check: what should work out of the box
Before digging deep into the settings, make sure the minimum requirements for wireless broadcasting are met.Errors at this stage occur in 30% of cases - users simply miss the obvious.
Three prerequisites:
- 📶 One Wi-Fi network: phone and TV must be connected to the same router (not to different ranges) 2.4 GHz/5 GHz if you have dual-band!. check the name of the network (SSID) both-device.
- 🔄 Active protocol: TV must support Miracast (for Android) or AirPlay (for iOS). On Xiaomi, this is a feature of Wireless display in quick settings.
- 📱 Compatible versions: phones on MIUI 12 and older theoretically support streaming, but with Android TVs TV 9 and below may be conflicts.
If one of the conditions is not met, further manipulation of the settings is useless. For example, many users do not know that the Xiaomi Mi TV Stick can not receive stream from the phone, only send it to the TV. and Samsung J series TVs (2016-2017) require a firmware update to work with Miracast.
2. Wi-Fi settings on Xiaomi phone: what prevents detection
Even if the phone and TV are on the same network, Xiaomi can block scanning of other devices due to energy savings or security restrictions. MIUI, which often get lost after updates.
Where to look for problems:
- 🔍 Energy Saving Mode: Go to Settings → Battery and productivity → Battery mode and select Performance. Energy saving mode turns off background network scanning.
- 🚫 Restrictions for applications: in Settings → Annexes → Application management → Three dots (menu) → Special access → Wi-Fi Direct File Transfer Check if System Services are blocked.
- 🔄 Network Resetting: Sometimes a full reset helps - Settings → Wi-Fi → Three points. → Additionally. → Resetting network settings.
Pay special attention to setting up Private DNS (in Settings → Wi-Fi → Additional). If it has a custom address (for example, 1.1.1.1 or dns.google), try to return the value Automatically - this solves the problem with device detection in 15% of cases.

Router Conflicts: Why One Network Doesn't Mean One Visibility
A router can “sever” communication between the phone and the TV even if both devices are connected to it. IP-address.
Top.-3 router-problem:
| Problem. | How to check | How to fix it |
|---|---|---|
| 🔒 Isolation of clients (AP Isolation) | Go to the router panel (usually 192.168.0.1 or 192.168.1.1) → Wi-Fi → Additional settings | Disable the AP Isolation or Client Isolation option |
| 📡 Incompatible Wi-Fi Standard | In the router settings, see the mode of operation (802.11 b/g/n/ac/ax) | Set 802.11n (2.4 GHz) or 802.11ac (5 GHz) – no mixed modes |
| 🔢 Conflict IP-address | On the phone in Settings → Wi-Fi → Current network → Additional view IP. Compare with IP TV (in its network settings) | In the router, fix static IP for both devices or reboot DHCP |
If you have a Xiaomi Mi Router, check the Wi-Fi Bridge settings (in Operating Mode). In Bridge Mode, devices in different subnets won’t see each other. Also, there is a bug with Band Steering (automatic switching between 2.4 and 5 GHz) on Xiaomi routers — try turning this feature off.
💡
If the devices can't see each other after the router changes, try temporarily disabling Wi-Fi encryption to see if the password is to blame. Don't forget to return the protection later!
4.Miracast and Wi-Fi Direct problems: protocols under the microscope
Miracast and Wi-Fi Direct are two different protocols, and Xiaomi can use either one depending on the TV model. If the phone can't see the TV, the conflict is likely to arise at the level of these technologies.
How to determine which protocol is used:
- 📺 On TV: For Samsung: Settings → General. → External devices → Miracast device. LG: Settings → Network → Wi-Fi Direct. for Xiaomi Mi TV: Settings → Connection and sharing → Wireless display.
- 📱 On Xiaomi phone: Swipe down for quick settings → Find the Wireless Display (or Screen Cast) icon. If you don't have the icon, go to Settings. → Connections and sharing → Wireless display.
Critical error: many users confuse Wi-Fi Direct (for file transfer) and Miracast (for screen broadcasting). If you try to connect through File Transfer to MIUI, nothing will work. You need to use Wireless display!
What if the TV only supports Wi-Fi Direct and not Miracast?
5. firmware updates: why the old version of MIUI breaks the connection
MIUI 12 and below had a Wi-Fi Direct driver bug that prevented Xiaomi phones from detecting devices on the network. MIUI 13/14 partially fixed the problem, but some models (such as the Redmi Note 8 Pro or POCO X3) require manual updates to the radio module.
How to check and update:
- Check out the current version of MIUI: Settings → About Phone → MIUI version.
- If the version is older than MIUI 13.0.5, update via Settings → System Update.
- For problem models (Redmi 9, Note 10), download the full firmware package from en.miui.com and install through System Update → Three dots → Select a firmware file.
After the update, reset the network settings (Settings → Wi-Fi → Additional → Network Reset) – this will clear the cache of Wi-Fi Direct drivers. If the problem persists, try rolling back to the stable version of MIUI (for example, from 14.0.3 to 13.0.8) – sometimes new builds contain regressive bugs.
adb shell pm clear com.miui.wifidirectThis command clears the cache of the service without losing other data.-->
6. Alternative ways of connecting: if nothing works
If standard methods don't work, try workarounds, which are less convenient, but often save you in "hopeless" cases.
4 working options:
- 🔌 USB-OTG + adapter: for televisions with USB-port can be used for adapter USB-C/MicroUSB → HDMI (For example, Xiaomi Mi USB-C to HDMI Adapter. Minus wires, plus zero latency.
- 📦 Google Chromecast: If you have Google TV Android TV, Buy a Chromecast (from 3,000) ₽). It works through Google Home and is more stable than Miracast.
- 🖥️ DLNA/UPnP: Applications like LocalCast or BubbleUPnP can stream media files (but not screen!) over the home network.
- 🌐 Cloud services: Xiaomi Cloud or Google Photos is suitable for streaming photos / videos (open the file on TV through the browser).
For Xiaomi Mi TV owners, there is an exclusive life hack: use the built-in Mi Home app on your phone. Go to Devices → Your TV → Remote remote → Screencast. This method bypasses the standard Miracast and works even on old firmware.
💡
If you often stream your screen to your TV, buy a low-cost Wi-Fi 6 router (e.g. Xiaomi). AX3000 2,500 ₽). Modern standards (802.11ax) They are better at multithreaded data transfer, and device detection problems are less common.
7.Diagnosis of malfunctions: when "iron" is to blame
If neither of these methods worked, it might be the hardware problem, which is the most unpleasant scenario, but it can be diagnosed.
Signs of hardware malfunctions:
- 📵 The phone doesn’t see any device through Wi-Fi. Direct/Miracast (even other smartphones).
- 🔥 Wi-Fi module overheats or shuts down when trying to broadcast.
- ⚡ After the fall / hit of the phone stopped working wireless functions.
To check, perform the Wi-Fi module test through the engineering menu:
- Type the code ##4636## on your phone keyboard.
- Go to Wi-Fi information → Wi-Fi Direct test.
- If the status says Error or Unsupported, the module is defective.
In the case of hardware failure, two options remain:
- Replacement Wi-Fi/Bluetooth-Module (cost for Xiaomi – from the 1 500 ₽).
- Use an external USB Wi-Fi adapter with Miracast support (e.g. TP-Link Archer T2U).
💡
Before you change the module, check if Wi-Fi is turned off at the firmware level. Sometimes after unsuccessful updates, MIUI blocks wireless interfaces, in which case flashing through Fastboot will help.
⚠️ Note: If you connect to a TV on a public network (hotel, cafe), most likely, the administrator has disabled the client-client function in the router settings. In this case, broadcasting via Miracast or Wi-Fi Direct is not possible - use alternative methods (for example, use alternative methods, HDMI-adapter).
