1. Preparing the terminal for connection

Before connecting the terminal to Wi-Fi, make sure the device is ready for setup. Here's what to check:

• 🔋 Battery charge: The terminal must be charged to at least 50%. If the charge is lower, connect it to the network using the original cable.
• 📶 Wi-Fi network availability: Make sure your router is turned on and distributing the network within the terminal's range (usually up to 10 meters indoors).
• 🔑 Wi-Fi password: Have the correct network password ready. If you've forgotten it, look it up on the router sticker or in your provider's account.
• 📱 Alternative Internet: In case of problems, connect a SIM card with mobile Internet (if your terminal model supports 4G).

If the terminal is new and not yet activated, first complete the activation process through the application Tinkoff Business Or by calling the bank's support line. Without activation, Wi-Fi setup will be unavailable.

2. Standard method: connecting via the terminal menu

This is the most reliable method that works on all terminal models. Tinkoff. Follow the instructions:

1. Turn on the terminal by pressing the power button (usually located on the side or back panel).
2. Wait for the main screen to load. If prompted, enter your PIN.
3. Go to the menu Settings (gear icon in the upper or lower right corner).
4. Select a section Net or Wi-Fi (the name may differ).
5. Activate the slider Wi-Fi (if it's disabled). The terminal will begin scanning for available networks.

3. Alternative ways to connect to the Internet

If the standard method didn't work or you don't have access to your router, try one of these options:

• 📶 Mobile hotspot: Share the Internet from your smartphone (Android or iPhone) and connect the terminal to this network. Minus: high traffic consumption.
• 🔌 Wired connection (Ethernet): If your terminal model supports a LAN port, connect it to the router with a cable. This is the most stable method.
• 📡 4G modem: use a USB modem with a SIM card (for example, from Megaphone or Beeline). Not all terminals support this method - check the documentation.
• 🔄 Bridge mode: If you have multiple routers, configure one of them in repeater (WDS) mode to strengthen the signal for the terminal.

⚠️ Attention: When using a mobile hotspot, disable automatic Wi-Fi disconnection on your smartphone (in the hotspot settings). Otherwise, the terminal will lose connection after 5-10 minutes of inactivity.

4. Common mistakes and their solutions

Even with the correct settings, the terminal may not connect to Wi-Fi. Let's look at the most common issues and how to fix them:

If the terminal gives an error IP conflict, reboot your router and terminal. Also, check if your terminal has a static IP address assigned to it on the network—this can cause conflicts.

How to find out the MAC address of a terminal?

MAC address of the terminal Tinkoff can be found in the menu Settings → About terminal → Network information or on a sticker on the back of the device. It looks like 12 pairs of characters separated by colons (for example, 00:1A:2B:3C:4D:5E).

5. Optimizing Wi-Fi for stable terminal operation

To ensure your terminal works smoothly, simply connecting it to the network isn't enough. Here are some tips for improving your connection:

• 📡 Select the correct Wi-Fi channel: In your router settings, set a fixed channel (for example, 6 or 11 for 2.4 GHz) to avoid interference from neighboring networks.
• 🔄 Update your router firmware: Outdated software may be causing connection issues. Check for updates in your router's web interface.
• 🔋 Use a backup communication channel: Configure the terminal to automatically switch between Wi-Fi and mobile Internet (if supported).
• 🛡️ Disable your router's smart features: For example, Band Steering (automatic switching between 2.4 and 5 GHz) may interfere with the terminal connection.

Critical moment: If you have multiple terminals running at your retail location, connect them to different Wi-Fi channels or use separate access points. Otherwise, payment processing may be delayed due to network congestion.

It is also recommended to enable the function QoS (Quality of Service) on the router and assign it to the terminal (maximum priority). This ensures that payment transactions won't be slowed down by other devices on the network.

6. Diagnosing problems with tests

If the terminal connects to Wi-Fi, but payments are not processed or the connection is unstable, run diagnostics:

1. Check your internet speed: In the terminal menu, find the section Network diagnostics and run the speed test. Minimum requirements: 1 Mbps for stable operation.
2. Ping test: In the same section, check the ping to the bank's servers. If the values ​​exceed 200 ms, contact your provider.
3. Error logs: V Settings → Event Log Look at the latest errors. For example, the code ERR_CONNECTION_TIMED_OUT indicates problems with the router.

If the terminal gives an error No connection with the bank, but Wi-Fi is connected, check:

• Is the router's firewall blocking outgoing connections to ports? 443 (HTTPS) and 80 (HTTP).
• Are there any time limits set on the router (for example, "Parental Control")?
• Have the DNS servers changed (try using 8.8.8.8 And 8.8.4.4 from Google).

7. Updating the terminal firmware for better compatibility

Outdated firmware may cause problems connecting to modern Wi-Fi networks (for example, with support WPA3). To update the terminal software:

1. Connect the terminal to the Internet using any available method (even via a mobile hotspot).
2. Go to Settings → System Update.
3. Click Check for updates.
4. If a new version is available, confirm the installation and wait for it to complete (the terminal will restart automatically).

⚠️ Attention: Do not turn off the terminal or interrupt the update process! This may cause the system to crash. If the update is stuck for more than 20 minutes, please contact support. Tinkoff.

After updating, check your Wi-Fi settings again—sometimes saved networks are reset.

What to do if the update is not found?

If the terminal doesn't see updates, but you know they exist (for example, support reported a new version), try:

1. Connect to another network (for example, a mobile hotspot).

2. Reset network settings in Settings → Network → Reset network settings.

3. Contact support indicating the terminal model and the current firmware version (you can find it in Settings → About terminal).
