Connecting to Wi-Fi in the metro on smartphones Xiaomi It seems like a simple task, but in practice, users encounter a host of nuances: from the network not appearing in the list to constant connection drops. In this article, we'll cover not only the basic setup steps but also hidden settings. MIUI, which will help stabilize the connection in the subway. We will pay special attention to models with Qualcomm Snapdragon And MediaTek — their behavior when connected to public networks can differ dramatically.
It's important to understand that Wi-Fi in the metro is not a regular home network. It uses roaming access points (in carriages) or stationary routers (at stations), which frequently change IP addresses and security settings. Xiaomi with shell MIUI 14/15 has built-in mechanisms for working with such networks, but they're not always enabled by default. We'll show you how to enable them and what to do if you still can't get a network connection.
The article is relevant for all modern models Xiaomi, Redmi And POCO (including Xiaomi 14, Redmi Note 13 Pro+, POCO F6). If you have an older model (produced before 2020), some menu items may differ—we'll warn you about this separately.
Why isn't Wi-Fi in the metro showing up in the list of available networks?
The most common problem is that the network simply isn't visible in the settings. There could be several reasons, and most of them have nothing to do with your phone, but with the subway infrastructure. Here are the key points:
- 📡 The network is disconnected at the station/in the carriageIn some cities, Wi-Fi is only available at stations (for example, in Moscow) or only on trains (like the St. Petersburg metro). Check your metro's official website for details.
- 🔄 Frequent change of access pointsOn a moving train, your phone may not be able to reconnect quickly between cars. This is especially true for budget models. Redmi with Wi-Fi modules
2.4 GHz. - 🔒 Hidden network (SSID not broadcast)Some metro operators hide the network name for security reasons. In this case, you'll have to enter the network name manually.
- 📱 MIUI limitations. In the settings Xiaomi By default, a "smart connection" filter may be enabled, which ignores networks with low signal strength.
To check whether the phone is to blame or the problem is on the metro side, try to find the network on another device (for example, on iPhone or laptop). If it is missing there too, it is not the matter XiaomiIf the network is available, but only your smartphone doesn't support it, proceed to the next sections.
Basic Wi-Fi setup in the metro on Xiaomi
If the network is visible but won't connect, start by checking the basic settings. Here are step-by-step instructions for MIUI 14/15:
- Open
Settings → Wi-Fi. - Make sure the Wi-Fi slider is turned on (should be blue).
- In the list of networks, find the name of Wi-Fi Metro (usually contains the words
METRO,FreeWiFior the name of the city). - Tap the network and wait for it to connect. If authorization is required, a browser will open.
Some stations require authorization via SMS or social media to access Wi-Fi. If the authorization page doesn't open automatically:
- 🌐 Open any browser and enter the address
1.1.1.1orneverssl.com. - 📱 If nothing happens, check if the connection is blocked VPN or firewall (for example, built in MIUI "Defender").
Is Wi-Fi enabled on your phone?
No active VPN connection|
Ad blockers are disabled in the browser|

Attention! On some models Xiaomi (especially with MediaTek Helio) After connecting to a public network, mobile data may disappear. This is due to the Wi-Fi priority in the settings. To fix:
- Go to
Settings → SIM cards and mobile networks. - Select your SIM card.
- Activate the option
Use mobile internet when Wi-Fi is poor.
Hidden MIUI settings for stable Wi-Fi in the metro
shell MIUI has hidden settings that can significantly improve Wi-Fi performance in metro conditions. These settings are not documented, but have been tested in practice:
First, let's activate it developer mode (if not already enabled):
- Go to
Settings → About phone. - Tap the item 7 times
MIUI version. - Enter your pattern or password.
Now open it Settings → Additional settings → Developer options and find the following options:
| Setting up | Recommended value | Effect |
|---|---|---|
Aggressive Wi-Fi/Mobile Data Switching |
Turn on | Switches between Wi-Fi and mobile data faster when the connection drops. |
Always look for networks |
Turn on | The phone will scan for networks even when the screen is off |
Wi-Fi High Performance Mode |
Turn on | Increases Wi-Fi module power (may reduce battery life) |
Limit background activity |
Disable | Allows applications to maintain a connection in the background. |
A critical detail for Xiaomi owners with MediaTek processors: the "High Performance Wi-Fi Mode" option may be missing from the developer options. In this case, try enabling "Wi-Fi Debugging"—this indirectly improves connection stability.
Resolving issues with authorization and the captive portal
Many users encounter a situation where Wi-Fi connects in the metro, but the internet doesn't work—instead, they're presented with a login page that doesn't load. This is due to captive portal (forced authorization system). Here's how to bypass common errors:
- 🔄 The authorization page does not openTry opening it manually.
http://captive.apple.comorhttp://connectivitycheck.gstatic.comin the browser. - 🚫 Browser blocking. Disable ad blockers (for example, in Chrome with the uBlock extension) or use a standard browser MIUI.
- 📱 "No Internet Connection" ErrorGo to .
Settings → Applications → Manage applications → Browserand clear the cache. - ⏳ Infinite page loadingTurn on airplane mode for 10 seconds, then turn it off and try connecting again.
If authorization goes through, but after a few minutes the Internet disappears, the problem may be in session timeoutIn many cities' metro systems, Wi-Fi connections are limited in time (for example, 30 minutes), after which you need to reconnect. To automate this process:
- Install the application Tasker or MacroDroid from Google Play.
- Create a task on
Disabling/enabling Wi-Fiat intervals of 25 minutes. - Add a condition to run the task only when connected to the metro network (by SSID name).
What should I do if SMS confirmation is required?
If you need to enter a phone number for authorization, but the SMS does not arrive:
1. Check your SIM card balance (sometimes operators block SMS when the balance is zero).
2. Try requesting the code again in 1-2 minutes.
3. If you use two-factor authentication (for example, via Telegram), temporarily disable it—some captive portal systems conflict with such services.
4. As a last resort, use a virtual number (services like SMS-Activate), but be aware of the security risks.
Optimizing battery consumption when using Wi-Fi on the metro
Constantly searching for and connecting to Wi-Fi on the subway can significantly reduce your phone's battery life. This is especially noticeable on models with small batteries (e.g., Xiaomi 13 Lite or POCO X5). Here's how to reduce battery drain without losing your connection:
- 🔋 Disable background network scanning for unnecessary applications:
Settings → Battery → App Selection → Restrict Background Activity. - 📶 Set a limit on mobile data consumption in the background:
Settings → SIM cards & mobile networks → Data usage → Background data. - ⚡ Use a dark theme (in the metro it’s also easier on the eyes):
Settings → Display → Dark Theme. - 🔄 Adjust adaptive brightness:
Settings → Display → Adaptive Brightness → Enable.
