How to choose the right Wi-Fi network on Xiaomi devices: from a smartphone to a smart home

Choosing the right Wi-Fi network on Xiaomi devices is a seemingly simple task, but it depends on Internet speed, connection stability and even battery consumption. Smartphones, tablets, Mi TVs, smart speakers and other brand equipment often offer a choice of several networks: 2.4 GHz, 5 GHz, and sometimes hidden corporate hotspots. Wrong choice can lead to lags in games, video interruptions or quick battery discharge.

In this article, we will discuss how to determine the optimal network for your Xiaomi device, what are the different standards? 802.11n, 802.11ac and 802.11ax (Wi-Fi 6, and we'll also give you a checklist to diagnose problems, and we'll focus on the hidden function. MIUI, It automatically switches between frequencies and why it is better to manually disable it.

1.2.4 GHz vs 5 GHz: which network to choose on Xiaomi

The main choice is between two bands: 2.4 GHz and 5 GHz. The first covers a larger area and passes better through walls, but suffers from interference (microwaves, neighboring routers); the second is faster and less busy, but has a shorter range.

  • ๐Ÿ“ถ 2.4 GHz: Suitable for large homes, devices away from the router (e.g. Yeelight smart bulbs at the end of the corridor) Up to 150-300 Mbps (depending on the standard).
  • โšก 5 GHz: ideal for smartphones Xiaomi 13/14, Mi TVs TV Q2 Or gaming devices. 433 Mbit/s (Wi-Fi) 5) before 1.2 Gbps (Wi-Fi) 6).
  • ๐Ÿ”„ Automatic selection: in MIUI There's a Smart Wi-Fi Switch that switches between frequencies, but it's often wrong -- it's better to turn it off (more on that below).

For example, if you're looking 4K-Video from Redmi Note 12 Pro+, Choose 5 GHz. And for a smart thermostat, Mijia in another room will be enough 2.4 GHz.

๐Ÿ“Š What network do you usually choose on Xiaomi?
Only 2.4 GHz
Only 5 GHz.
Automatic choice
Depends on the device.

2.How to Check Which Network Is Best at Catching in Your Home

Before you choose a network, test the signal level at different points in the apartment.

  1. Open Settings โ†’ Wi-Fi on a Xiaomi smartphone.
  2. Tapping on the network and looking at the signal level (decibels, dBm) is optimal: from -50 to -70 dBm.
  3. If the value is less than -80 dBm, the network will slow down.

For a more accurate analysis, use the WiFi Analyzer app (available on Google Play) to show the load of channels and help you choose the least busy one. For example, if 2.4 GHz all your neighbors are sitting on channel 6, switch to 1 or 11.

๐Ÿ’ก

MIUI 14+ has a hidden menu with detailed Wi-Fi statistics. To open it, go to Settings โ†’ About Phone, tap 5 times on the MIUI version, then return to Wi-Fi โ†’ Additional โ†’ Network Statistics.

3. set up automatic switching (and why it is better to turn it off)

The MIUI Smart Wi-Fi Switch feature promises to automatically select the best network, but in practice it often switches at the wrong time, such as during an online game or video call. Here's how to control it:

  • ๐Ÿ”ง Disconnection: Settings โ†’ Wi-Fi โ†’ Additionally. โ†’ Auto-switch Wi-Fi (uncheck the box).
  • ๐Ÿ”„ Manual Priority: If you leave the function on, add priority networks manually through Settings โ†’ Wi-Fi โ†’ Additionally. โ†’ Network priority.
  • ๐Ÿ“ฑ Exceptions: For critical devices (e.g., Xiaomi Pad 6 for work), turn off auto-switching completely.

Mi TVs don't have this feature, you always have to choose the network manually, but on Xiaomi Mi Router routers you can set up band steering in the router's web interface.

What to do if Xiaomi smartphone does not see 5 GHz?
If your device does not detect a 5GHz network, check: 1. Does your router support this range (the case must be labeled "Dual-Band"). 2. Is 5GHz enabled in the router settings (sometimes it is disabled by default). 3. Standard compatibility: older smartphones (such as Redmi 4X) only support 802.11n at 2.4GHz.

4. Features of choosing a network for different Xiaomi devices

Not all of the brandโ€™s gadgets work the same way with Wi-Fi. Here are the key differences:

The deviceRecommended networkNotes
Xiaomi 13/14 Ultra5 GHz (Wi-Fi 6/6E)Supports 160 MHz channels โ€“ use a router with Wi-Fi 6 for maximum speed.
Redmi Note 125 GHz or 2.4 GHzWi-Fi 5 (802.11ac) is enough for most tasks, but does not pull 160 MHz.
Mi TV Q2 75"5 GHz (required)For 4K HDR streams, you need a speed of 50 Mbit / s. 2.4 GHz will not pull.
Yeelight, Mijia2.4 GHzSmart lamps and sensors only work at 2.4GHz. They don't support 5GHz!
Xiaomi Watch 2 Pro2.4 GHz (Wi-Fi Direct)Uses Wi-Fi only to sync with your phone, speed is not critical.

For a smart home (for example, Xiaomi Home with the Mi Home Gateway hub), always choose 2.4 GHz - most sensors do not know how to work at 5 GHz. But for the Mi Box S or Mi TV Stick, 5 GHz is better suited - so there will be no lags when watching movies.

๐Ÿ’ก

Xiaomi smart devices (lamps, sensors, sockets) only work at 2.4GHz. If your router hides an SSID for this range, they won't connect!

5. Solving Wi-Fi Connection Problems

If the network is detected but not connected, or the connection is constantly broken, check:

Wrong password|Resetting network settings to Settings โ†’ Wi-Fi โ†’ Additionally. โ†’ Network management|Router firmware update|Verification MAC-filtering in router settings|Changing Wi-Fi to a less busy channel-->

A common problem on Xiaomi is the error "Connection saved but without internet access."

  • ๐Ÿ”’ Encryption incompatibility: the router uses WPA3, The device only supports WPA2. Solution: in the router settings, select WPA2/WPA3 Mixed.
  • ๐Ÿ“ก Hidden SSID: If the network is not broadcasting the name, some Xiaomi devices cannot connect to it. SSID.
  • ๐Ÿ”„ Conflict IP: reset the settings TCP/IP In Settings โ†’ Wi-Fi โ†’ Additionally. โ†’ DHCP (select "Automobile").

On Mi TVs, if you have problems with Wi-Fi, try an alternative way to connect:

  1. Go to Settings โ†’ Network โ†’ Connect via WPS.
  2. Press the WPS button on the router for 2 minutes.
  3. The TV will connect automatically without entering a password.

If you lose Wi-Fi after the MIUI update, try resetting your network settings through Settings โ†’ System โ†’ Settings Reset โ†’ Resetting your Wi-Fi, Bluetooth and mobile data settings. This will delete all the saved networks, but solve most software failures.

6. Optimizing Wi-Fi for Games and Streaming on Xiaomi

For online gaming (Genshin Impact, PUBG Mobile) or streaming (Twitch, YouTube in 4K), connectivity stability is critical, not just speed. Here's how to achieve it:

  • ๐ŸŽฎ Game mode: on routers Xiaomi Mi Router AX6000 Enable Game Acceleration in the web interface.
  • ๐Ÿ“Š QoS (Quality of Service): Prioritize traffic for your smartphone in your router settings MAC-address.
  • ๐Ÿ”Œ Wired connection: for Mi TV Xiaomi Pad or Xiaomi Pad to use adapter USB-C โ†’ Ethernet (e.g. Xiaomi) USB-C Gigabit Ethernet Adapter).

To reduce ping in games:

  1. Connect to the 5GHz network.
  2. B Settings โ†’ SIM-maps and mobile networks โ†’ Additionally. โ†’ Select Network Mode Only LTE/5G (If you play through the mobile Internet).
  3. Turn off background app updates in Settings โ†’ Apps โ†’ Autorun.

On Mi TVs for smooth 4K HDR playback, enable hardware acceleration in Settings โ†’ Display and Sound โ†’ Additional settings โ†’ Hardware decoding.

๐Ÿ’ก

For online games on Xiaomi, it is better to use 5 GHz with a fixed channel (for example, 36 or 149), rather than โ€œAutoโ€.

7.Security: How to Protect Wi-Fi Connection

Xiaomi devices are often targeted for Wi-Fi attacks due to the popularity of the brand.

  • ๐Ÿ•ต๏ธ Fake access points: Attackers create networks with names like Xiaomi_Hotspot or Mi_Free_WiFi. Never connect to unknown networks!
  • ๐Ÿ”“ Vulnerabilities in MIUI: In older versions of the firmware, there was a vulnerability CVE-2020-14125, It's a traffic-stealing system!
  • ๐Ÿ“ก Router Attacks: If you use Xiaomi Mi Router, change the standard password of the admin panel (admin/admin).

How to defend yourself:

  1. Enable VPN for important connections (such as Xiaomi VPN or ProtonVPN).
  2. Turn off WPS in router settings โ€“ this protocol is easy to crack.
  3. Use WPA3 (if the device supports) or WPA2-AES (not TKIP!).
  4. In Settings โ†’ Wi-Fi โ†’ Additionally, disable the Connection to open networks.
How to check if your Wi-Fi devices are connected?
Go to the router web interface (192.168.31.1 for Xiaomi), then DHCP โ†’ Customer list, if you see the unknown MAC-Addresses, change the network password.

โš ๏ธ Note: If your Xiaomi smartphone connects to public Wi-Fi (in cafes, airports), disable Autoconnection in network settings. KRACK intercept.
