Roaming Wi-Fi on Xiaomi: how to automatically switch between networks

Have you ever noticed how your Xiaomi smartphone suddenly loses its Wi-Fi connection and then connects again a second later to another hotspot? It's not a failure, but the operation of the Wi-Fi roaming feature. Technology that should make our lives easier often raises questions: why the phone itself switches between networks, how to control it, and whether automatic roaming can be turned off if it interferes.

In this article, we will analyze what is Wi-Fi roaming on Xiaomi, how it works on different models (from Redmi Note to Xiaomi). 14), And you'll also learn how to prioritize networks, avoid connection problems in public places, and what to do if roaming isn't working properly. MIUI 12/13/14 — They affect the location of settings and the logic of switching.

Spoiler: If you often experience communication interruptions when moving around your home or office, the problem may not be in the router, but in the roaming settings on your Xiaomi.

What is Wi-Fi roaming and why is it needed

Roaming Wi-Fi is a technology that allows a device to automatically switch between access points with the same name (SSID) without breaking the connection. For example, when you move from room to room and there are multiple routers or mesh systems installed at home, the smartphone must jump from one signal source to another, choosing the strongest one.

On Xiaomi, this feature works in two scenarios:

• 📶 Local roaming: switching between points on a network (for example, between points on a network) Xiaomi_Router_5G and Xiaomi_Router_2.4G in your apartment).
• 🌍 Global roaming: Automatic connection to open or stored networks outside the home (cafes, airports, etc.).

The main goal is to provide a stable connection without manual network selection, but in practice, Xiaomi users often complain about:

• ⚡ Frequent switching communication interruptions.
• 🔄 Connecting to weaker networks instead of more powerful ones.
• 🔒 Automatic connection to insecure open networks.

This is due to the peculiarities of roaming implementation in MIUI. For example, a smartphone can “stick” at a point with a weak signal, instead of switching to a closer one, or vice versa – jumping too often between networks, which leads to lags in games or video calls.

How Wi-Fi roaming works on Xiaomi: technical details

The roaming algorithm on Xiaomi depends on three factors:

1. MIUI version: In MIUI 12 and older, the switching logic is different from earlier versions.
2. Smartphone model: flagships (such as the Xiaomi 13 Pro) use more aggressive roaming to support high speeds, and budget models (such as the Redmi 10A) can save battery power by scanning networks less often.
3. Router Settings: If you have a mesh system (e.g., Xiaomi Mi Mesh Router), the smartphone will switch between nodes differently than when working with individual routers.

Technically, the process looks like this:

1. The smartphone constantly scans the air for networks with saved SSIDs.
2. When a network with a stronger signal is detected (usually a difference of ≥10 dBm) or a higher speed (e.g., a switch from 2.4 GHz to 5 GHz), the device initiates a reconnection.
3. If a new network requires authorization (e.g., at a hotel), Xiaomi can either request a password or skip it, depending on the security settings.

Important: MIUI 14 adds Smart Roaming, which takes into account not only signal strength, but also channel load, connection type (e.g. 5 GHz priority over 2.4 GHz) and even network stability history.

Where to find Wi-Fi roaming settings on Xiaomi

Depending on the version of MIUI, the path to roaming settings may vary. Here are the current instructions for different firmware:

Some models (such as the POCO F5 or Redmi K60) may need to enable developer mode to access advanced roaming settings.

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version.
3. Back to Settings → Additionally. → For developers.
4. Find the option Aggressive Wi-Fi roaming (if you have one on your model).

⚠️ Attention: on some firmware (MIUI Global for Europe) roaming may be hidden due to regional restrictions, in which case resetting network settings or installing alternative firmware (e.g. xiaomi.eu) will help).

How to turn off or configure Wi-Fi roaming on Xiaomi

If automatic roaming interferes (for example, the smartphone constantly clings to weak networks or reconnects too often), it can be turned off or reconfigured.

Open the Settings. → Wi-Fi|Tap on. ⚙️ near the connected network|Select Additional → Smart roaming|Move the slider to the off position.-->

For a more subtle setup:

1. Priority of networks: in MIUI 12+ You can manually set the order of the connection. → Wi-Fi → ⚙️ Additionally. → Network priority Drag networks in the right order (top priority).
2. Disable Auto Connection: If your smartphone is clinging to open networks in cafes or airports, turn off the option: Settings → Wi-Fi → ⚙️ Additionally. → Auto-connection to open networks
3. Fixing on the same frequency: if the router supports 2.4 GHz and 5 GHz with one SSID, But the smartphone is constantly jumping between them, so you can make it use only one lane. → Wi-Fi → ⚙️ Additionally. → Select only 5 GHz or only 2.4 GHz.

On Qualcomm Snapdragon models (such as Xiaomi 12T or POCO X5 Pro), there is a hidden Wi-Fi Roaming Aggressiveness setting that adjusts the "aggressiveness" of the switching, to find it:

1. Enable the developer mode (see the instructions above).
2. Go to Settings → Additional → For developers.
3. Find Wi-Fi roaming aggression and choose one of the values: Low - switches less often, saves battery. Medium - balance between stability and economy. High - actively looking for the best network, but burns the battery faster.

⚠️ Attention: on some firmware (MIUI China) changing roaming settings can cause all Wi-Fi networks to reset. Before experimenting, save passwords in a text file or use the backup function Settings → Memory. → Backup.

Wi-Fi roaming problems on Xiaomi and their solutions

Even with the right settings, roaming can work incorrectly, and here are the typical problems and ways to solve them:

If none of these methods worked, try resetting your network settings:

1. Go to Settings → System → Resetting settings.
2. Select Reset Wi-Fi, Bluetooth and mobile data settings.
3. Confirm the action and restart the device.

For comparison, here is how roaming is implemented by competitors:

If you use Xiaomi in an ecosystem with routers of the same brand (e.g. Xiaomi Router) AX6000), roaming will work better than other manufacturers' devices, and that's because of optimizations in the Internet. MIUI Xiaomi equipment.

💡

On Xiaomi’s flagship 13/14 series, roaming is more stable thanks to the Qualcomm FastConnect chip, which supports 802.11k/v/r standards for quick switching between points.
