Modern point-of-sale terminals such as Evotor, have almost entirely switched to wireless communication protocols for fiscal data transfer and cloud services. The absence of a physical Ethernet cable frees up the cashier's workspace, but requires proper network setup. A stable internet connection is not just a convenience; it's a legal requirement for timely receipt submission to the Fiscal Data Operator (OFD) and the Federal Tax Service.
The connection process may seem simple, but the operating system AndroidThe system on which the terminal software is based has its own peculiarities. Incorrectly set time, DNS, or roaming parameters can block the entire device, even if the password is entered correctly. In this article, we'll cover not only the basic procedure but also hidden settings that are often overlooked.
Equipment preparation and data verification
Before setting up, make sure the device itself is ready to work with wireless networks. Turn on the terminal and wait for the operating system to fully load. If the device is new or has been reset to factory settings, it may prompt you to select a language and region at the very beginning.
You'll need to know your network's exact name (SSID) and password to access it. Pay attention to case sensitivity: the system distinguishes between lowercase and uppercase characters. It's also worth checking in advance whether MAC address filtering is enabled on your router, as Evotor terminal may be blocked at the router level.
Make sure there's no strong interference from microwave ovens or powerful radiation sources within the router's range, as these could interrupt the connection during receipt processing. Signal stability is critical for business processes.
Basic Wi-Fi setup on the terminal
To get started, go to the device's main menu. This is usually done by pressing the Home button or swiping up from the bottom, depending on the firmware version. Find the "Settings" icon (the gear icon) and open the wireless network section.
In the menu that opens, find the item Wi-Fi and move the switch to the active position. The terminal will begin scanning for available networks. All detected access points and their signal strengths will be displayed in the list.
Find your network name in the list and click on it. If the network is hidden, select "Add network" and enter the SSID manually. A field for entering the security key will then appear.
- 📶 Enter the password for your Wi-Fi network, carefully checking each character.
- ⚙️ Make sure the "Show password" box is unchecked to prevent typing errors.
- 🔌 Click the "Connect" button and wait until the "Connected" status appears.
☑️ Connection check
Once successfully connected, a corresponding icon should appear at the top of the screen (in the status bar). If the icon is flashing or an exclamation point appears, this means there is a physical connection, but the internet is not working.
Setting up date, time, and DNS servers
One of the most common reasons why Evotor The reason why the device doesn't work over Wi-Fi is because the time is out of sync. Security protocols (SSL/TLS) used to communicate with the data operator and banks require that the device's time be accurate to the minute.
If the time is incorrect, security certificates are invalidated and the connection is blocked. Go to the "Date & Time" section in Settings. It's recommended to set automatic syncing via network, but if Wi-Fi isn't already set up, you'll need to set the time manually.
It's also important to pay attention to DNS settings. Providers provide their own servers by default, which can be slow or block some requests. For cash registers, it's often recommended to use public DNS from Google or Yandex to improve response speed.
⚠️ Attention: Changing DNS servers may require rebooting the network interface. If you lose internet access after changing the settings, reset the settings to "Automatic."
For advanced users, manual IP address configuration is available. In the list of networks, click on the name of your access point and select "Edit Network" or "Advanced." In the "IP Settings" field, select "Static."
IP address: 192.168.1.150Gateway: 192.168.1.1
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 8.8.4.4
Using a static IP address is useful if you need to set up port forwarding on a router to remotely control the terminal from an accountant's computer.
Why change DNS at the checkout?
Changing DNS servers to public ones (e.g., 8.8.8.8) often solves the problem when Wi-Fi is connected but receipts aren't being sent. Provider DNS servers sometimes lose packets or are slow in resolving the addresses of the OFD servers.
Troubleshooting Roaming and 5GHz Bandwidth Issues
Modern routers often operate in two bands: 2.4 GHz and 5 GHz. Older models Evotor or devices with cheap Wi-Fi modules may not see 5 GHz networks or work with them unstably.
If your terminal constantly loses the network, try dividing the ranges into different names (SSID) in the router settings, for example, MyShop_2.4 And MyShop_5Connect your cash register exclusively to a 2.4 GHz network, as it has better penetration through walls and shelves containing merchandise.
Another critical setting is "Roaming." Evotor's Android interface has a setting that allows the device to search for a better network, even if the current one is working. This can be detrimental to a brick-and-mortar cash register: the terminal will constantly try to reconnect, causing connection interruptions.
- 📡 Go to the advanced Wi-Fi settings on the terminal.
- 🚫 Find the option "Always search for network" or similar and disable it.
- 💾 Save the settings and reboot your device.
Disabling the constant network search saves battery power (for standalone models) and processor time, which is better spent on processing transactions.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Frequency range | 2.4 GHz | Better stability and penetration |
| Wi-Fi channel | 1, 6 or 11 | Minimizing interference from neighbors |
| Security protocol | WPA2-PSK | Maximum compatibility |
| Roaming | Turned off | Prevents breaks at one point |
Setting up Wi-Fi via Ethernet (for models with LAN)
Some models Evotor, especially stationary versions of the type 7.2 or 10, can have an Ethernet port or be connected via a USB adapter (LAN-to-USB). This is a more reliable method, but it requires setting connection priorities.
If a cable is connected to the terminal but you want to use Wi-Fi as a backup channel or vice versa, you need to properly configure the system's priorities. Android usually automatically selects a wired connection if one is active.
To set up a backup channel, make sure the Wi-Fi module is enabled and the network is saved. If the cable is interrupted, the system should automatically switch to the wireless network, unless disabled in the developer or network settings.
Make sure that the DHCP server on the router is distributing addresses correctly, or set static IP addresses for each interface from different subnets if this is a corporate network.
Diagnostics and common connection errors
Even with the correct settings, errors can still occur. The most common one is "Obtaining IP address...," which takes forever. This indicates that the terminal is unable to receive a response from the router's DHCP server.
In this case, rebooting the router will help. Also, check that the address pool isn't full. If there are many devices on the network, the router may simply not be able to assign new IP addresses. The solution is to increase the DHCP range or reserve an address for the cash register's MAC address.
Another error is "Authentication Error." The problem here is almost always with the password or encryption type. Make sure your router isn't set to mixed WPA/WPA2 mode; try setting it to strict WPA2-PSK (AES).
⚠️ Attention: If the terminal is connected to a public network (such as a shopping mall or cafe) that requires browser authorization (Captive Portal), fiscal data may not be transmitted. Evotor requires direct internet access without redirection to login pages.
For a more in-depth diagnosis, you can use Wi-Fi analysis apps available in the Evotor app store. They will display the signal strength in dBm. A value above -70 dBm is considered good, while a value below -80 dBm indicates poor reception and may result in lost receipts.
FAQ: Frequently Asked Questions
Is it possible to share Wi-Fi from a phone to Evotor?
Yes, this is possible, but not recommended for permanent use. Mobile internet is less stable, has a high ping, and drains your phone's battery. Use this method only as a temporary solution if your primary connection fails.
Why doesn't Evotor see the 5 GHz network?
Most likely, your terminal has an older Wi-Fi module (802.11 b/g/n), which doesn't physically support the 5 GHz frequency. Switch your router to 2.4 GHz mode or create a guest network on that frequency.
How do I reset network settings on Evotor?
Go to Settings → System → Reset settingsSelect "Reset Network Settings." This will delete all saved Wi-Fi passwords and Bluetooth settings, but will not affect your inventory system or product database.
Do I need a fixed IP address to operate the cash register?
For routine receipt processing, a fixed IP address is not required; a dynamic one is sufficient. A static address is only required for complex direct integration with 1C or for remote administration.
