Why you can't connect to Wi-Fi in the metro: We'll look at all the reasons and provide working solutions.

Are you standing on the platform or riding in a train, trying to connect to free Wi-Fi in the metro, but your smartphone stubbornly refuses to find a signal? Problems connecting to public Wi-Fi in the metro affect 60% of passengers, and there can be dozens of reasons: from trivial errors in your phone's settings to technical limitations from your provider. In this article, we'll explore the issue. all possible reasons, why you can't connect to Wi-Fi in the metro, and we'll also give you step-by-step instructions on how to solve the problem Android, iPhone and other devices.

It's important to understand that Wi-Fi in the metro isn't like a regular home network. It has its own authentication rules, session time limits, and even geofenced coverage. For example, in the Moscow metro, MT_FREE works on the principle of "one device - one session per day", and in St. Petersburg PETERSTAR You may need to re-authorize when transferring. If you don't understand these nuances, even a working smartphone will refuse to connect. Below, we'll examine each cause separately, from the simplest to the most complex.

Let's note right away: if you have obsolete device (released before 2018), connection problems may be due to the lack of support for modern Wi-Fi standards (e.g. 802.11ac or Wi-Fi 6). In this case, the only solution is to replace the device or use an external adapter. But let's take things in order.

1. Authorization issues: why the system doesn't accept the phone number

The most common reason is - authorization failure On the Wi-Fi portal. Most metro systems require you to enter your phone number and receive a confirmation code via SMS. If you encounter an error at this point, check the following:

• 📱 Number format: many systems only accept numbers in international format (+79123456789). If you enter 89123456789 or 9123456789, authorization will not pass.
• 🔄 Repeat SMS request: Sometimes the code doesn't arrive the first time. Wait 1-2 minutes and request a resend. The Moscow metro limits you to three attempts per day.
• 🚫 Blocking a number: If you have already connected to this network today, the system may block re-authorization. For example, in MT_FREE The rule "one number - one session per 24 hours" applies.
• 📵 Problems with the operator: If you don't receive any SMS messages at all, check your balance (some plans require paid SMS) or contact your mobile operator's support team.

If you are sure that the number was entered correctly, but authorization still fails, try:

1. Restart your phone and try again.
2. Connect through a different browser (for example, if you usually use Chrome, try it Firefox or Safari).
3. Clear browser cache: in Android this is done in Settings → Applications → Browser → Storage → Clear cache.

⚠️ Attention: Some metro systems (for example, in Yekaterinburg) require a bank card for authorization. If you don't have a card from the required bank, you won't be able to connect.

2. Technical network limitations: why is Wi-Fi present but not connecting?

Even if the network MT_FREE, PETERSTAR If another connection is listed as available, the connection may fail due to technical limitations. Here are the most common reasons:

• 📡 Network congestion: During peak hours (7:00–10:00 and 17:00–20:00), the number of connected devices exceeds the equipment's limits. In this case, new connections are blocked.
• 🔒 MAC filtering: Some metro networks use filtering by MAC address devices. If your device was previously blocked (for example, for suspicious activity), you won't be able to connect.
• 📶 Weak signal: In some cars or between stations, the signal level drops below the connection threshold. This is especially true for older trains with metal bodies.
• ⏱️ Session time limit: On the Moscow metro, a session lasts 30 minutes, after which re-authorization is required. If you fail to confirm your connection in time, access is blocked.

To check if the network is overloaded, try connecting during off-peak times (such as during the day). If the problem is MAC address, you can try to change it (to Android This is done through the engineering menu or special applications like MAC Address Changer). However, keep in mind that the change MAC may disrupt the operation of other networks.

Since 2026, the Moscow Metro has implemented a rule: if a device connects to MT_FREE more than five times in a week, it will automatically be greylisted and its connection blocked for 24 hours. This is designed to combat bots and abuse. If you frequently use the metro, use alternative internet access methods (mobile data or a VPN).

• ⚙️ Airplane mode or power saving: If airplane mode is enabled, Wi-Fi is automatically disabled. iPhone check Settings → Airplane Mode, on Android - swipe down the notification panel.
• 🔄 Automatic connection: If you have previously disabled automatic connection to MT_FREE, your phone will no longer attempt to connect automatically. Enable this option in your Wi-Fi settings.
• 🔒 Incorrect network settings: If you have manually changed network settings (for example, IP address or DNS), this may interfere with the connection. Reset the settings to factory settings.
• 📱 Outdated firmware: on older versions Android (below 10) or iOS (below 14) may not have the necessary security protocols to connect to public networks.

To reset network settings on Android:

1. Go to Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
2. Confirm the action.

4. Metro equipment problems: when the provider is to blame

The problem isn't always on your end. Metro Wi-Fi is provided by specialized providers, and they, too, experience outages:

• 🔌 Equipment shutdown: Access points can fail due to power surges or scheduled maintenance. For example, in the Moscow metro, maintenance is carried out at night, but sometimes outages occur during the day as well.
• 📡 Router malfunction: If the main router at a station fails, Wi-Fi will be unavailable until the equipment is replaced. This most often happens at new or renovated stations.
• 🔒 Changing security settings: The provider may update the encryption protocol (for example, from WPA2 on WPA3), and old devices will stop connecting.
• 📵 Geographic restrictions: In some metro systems, Wi-Fi only works in stations, but not in tunnels. For example, in Minsk, the network Minsk Metro Free Available in lobbies only.

It's easy to check whether the problem is on your end or your ISP's: ask other passengers if their Wi-Fi is working. If everyone is experiencing the same issue, it's the ISP's fault. In this case, the only option is to wait for the network to be restored.

You can also contact the metro support:

• In Moscow: +7 (495) 539-54-54 (24 hours a day).
• In St. Petersburg: +7 (812) 329-34-34.
• In other cities: numbers are listed on the official websites of the metro systems.

⚠️ Attention: In 2026, several cities (such as Kazan and Novosibirsk) began transitioning to a new authentication system using the Metro Wi-Fi app. If you don't have this app installed, you won't be able to connect to the network.

• 🛡️ Turn off sharing: In the Wi-Fi settings, disable options like Network Discovery (on Windows) or File sharing (on macOS).
• 🔄 Do not log into your personal accounts: Avoid entering logins/passwords from banks, social networks, or email on public networks.
• 📱 Update your software: Outdated versions of OS or browsers are vulnerable to attacks. Check for updates in Settings → Software Update.

If you need to access your personal account urgently (for example, to pay a bill), use mobile data instead of Wi-Fi. You can also use incognito mode in the browser and do not save passwords.

For maximum security, set up on your phone DNS from Google or Cloudflare:

1. On Android: Settings → Wi-Fi → Advanced → IP Settings → Static → DNS1: 8.8.8.8, DNS2: 8.8.4.4.
2. On iPhone: Settings → Wi-Fi → (i) next to the network → Configure DNS → Add server → 1.1.1.1.

FAQ: Answers to Frequently Asked Questions

Why does Wi-Fi in the metro ask for authorization every time?

This is a standard security measure. On most metro systems, a session is valid for a limited time (from 30 minutes to 24 hours). After the session expires, reauthorization is required. A session may also be reset when switching between stations or after prolonged inactivity.

Is it possible to connect to Wi-Fi in the metro without a phone number?

In most cities, no. SMS authentication is mandatory to prevent abuse. However, in some metro systems (for example, in Minsk), you can connect via social networks (VK, Telegram) or banking applications.

Why is Wi-Fi slow in the metro?

Speed ​​depends on the number of connected devices. During rush hour, the channel is congested, and speeds can drop to 1–2 Mbps. Distance to the access point also plays a role: the signal is weaker in train cars further from the station.

Can I use a VPN to connect to Wi-Fi on the subway?

Yes, but this doesn't always help. Some networks block traffic through the VPN. If authorization fails, try disabling the VPN for the duration of the connection and then re-enabling it.

What should I do if the internet doesn't work after authorization?

Check your proxy settings: sometimes Wi-Fi in the metro requires manual proxy server configuration. Also, try changing your DNS (as described in the security section) or rebooting your device.
