Modern retail is unthinkable without constant access to the global network, and Evotor smart terminals have become the de facto standard for small businesses. These devices run on an operating system Android, which opens up a wide range of possibilities, but also requires proper initial setup. Connecting the Evotor cash register to the Internet via Wi-Fi is the first and most critical step before launching the system, as without communication, neither the sale of goods, nor the fiscalization of receipts, nor work with cloud accounting services is possible.
Businesses often encounter situations where a device simply can't see the network or can't log in, which halts the entire workflow. In this article, we'll cover all the details of connection, from choosing a router to resolving complex issues with drivers and security protocols. You'll learn how to set up a static IP address and why this may be essential for the smooth operation of your retail outlet.
Connection stability directly impacts receipt processing speed and customer satisfaction. Incorrect wireless module configuration can lead to time desynchronization, errors when sending data to the fiscal data operator, and software update issues. Therefore, it's important not just to "get online," but to do it correctly, ensuring a reliable communication channel for your business.
Wireless network requirements for stable operation of Evotor
Before configuring the terminal itself, you need to ensure that your infrastructure is ready to provide a high-quality signal. Evotor smart terminals, such as the following models 2.0, 7.2 or 10, are equipped with Wi-Fi modules operating in the 2.4 GHz band. This is the standard frequency range that provides good coverage but is often congested in shopping malls and office buildings.
Minimizing interference is crucial to ensure smooth operation of the checkout area. If your router is dual-band and broadcasts both 2.4 GHz and 5 GHz networks with the same SSID, the checkout may attempt to connect to a less suitable band or constantly switch between them, causing connection interruptions. It is recommended to separate networks by name or force the router to switch to compatibility mode if problems are observed.
It's also worth paying attention to security standards. Although modern devices support WPA2/WPA3Sometimes older POS software firmware can conflict with the latest encryption protocols. In this case, temporarily downgrading the security level to WPA2-PSK (AES) helps diagnose the problem. Avoid using open networks without a password to transmit fiscal data, as this violates payment information security requirements.
⚠️ Please note: If you are using a corporate network with login and password authentication (Enterprise), you will not be able to connect using the standard POS software. You will need to create a Guest Network on your router with simple authentication using an access key.
- 📶 Use the 2.4 GHz band for maximum compatibility with all terminal models.
- 🔒 Use WPA2-PSK (AES) encryption type to balance security and compatibility.
- 📡 Make sure that your router does not hide the SSID (network name), as manual entry may not be available.
- 🔋 Check the cash register's battery charge before setting up to prevent the device from going into sleep mode.
Step-by-step instructions: connecting via the standard menu
Setting up a wireless connection on Evotor terminals is intuitive and similar to setting up any Android smartphone. First, you need to access the system menu, hidden from the standard cashier interface. On the desktop, find and click the icon. Settings, which usually looks like a gear. If you're in checkout mode, first tap the menu button (three dots or a hamburger icon) and select log out.
In the menu that opens, find the section Wi-Fi or Wireless networksIf it's off, move the slider to the active position. The device will automatically begin scanning for available space. After a few seconds, a list of detected networks will appear on the screen. Find your router's name (SSID) in the list and tap it.
After selecting a network, the system will ask you to enter a password. Be careful when entering it: use an uppercase keyboard if the password requires it, and pay close attention to the case of the letters, as passwords are case sensitiveAfter entering, press the button ConnectIf the credentials are correct, the "Connected" status will appear under the network name, and a signal strength icon will appear at the top of the screen (in the status bar).
☑️ Connection check
It's important to note that after a successful connection, the system may take some time to establish a connection with time servers and update updates. Don't rush to start punching receipts; allow the device 1-2 minutes for background synchronization. This ensures that the time on receipts is accurate, which is a legal requirement.
Setting up a static IP address for the cash register
In some cases, dynamic address allocation (DHCP) can lead to unstable operation, especially if there are many devices on the network or the router periodically reboots, changing the cash register's IP address. For retail outlets where peripheral equipment (scanners, scales) is connected to the cash register or access is configured from an accountant's computer, it is recommended to use static IP addressThis assigns a permanent "digital address" to the terminal on the local network.
To set up a static IP, in the Wi-Fi menu, click on your network name (or the gear icon next to it) and select "Advanced" or "IP Settings." By default, it's set to "DHCP." Change it to "Static." You'll now need to enter the information manually. Typically, this includes the IP address, subnet mask, gateway, and DNS servers.
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
The table below provides sample settings for popular routers to help you navigate the numbers. Please note that the register's IP address must be in the same subrange as the router, but not the same as the router's IP address or the addresses of other devices.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP address | Unique address of the cash register on the network | 192.168.0.25 |
| Gateway | Your router's address | 192.168.0.1 |
| Network mask | Determines the size of the network | 255.255.255.0 |
| DNS 1 | Primary name server | 8.8.8.8 (Google) |
Why do you need a second DNS?
A second DNS server (e.g., 8.8.4.4) acts as a backup. If Google's primary server (8.8.8.8) is temporarily unavailable or overloaded, the checkout will automatically switch to the backup, and internet access will not be lost. This increases system fault tolerance.
Using USB Wi-Fi adapters on Evotor
Not all Evotor smart terminal models have a built-in Wi-Fi module. For example, some basic models or specialized modifications may require an external adapter. There are also situations where the built-in module fails or the signal is too weak due to the design of the cash register installation location. In such cases, external Wi-Fi adapters can be used. USB Wi-Fi adapters.
It's critical to understand that the Evotor cash register runs on a specific version of Android, and drivers for common computer devices aren't installed by default. Not all chipsets are supported. Adapters based on chips demonstrate the best compatibility. Realtek (for example, RTL8188, RTL8192 series) and MediaTek (Ralink). Adapters from brands like TP-Link or D-Link may work, but only if they use a supported chipset.
The connection process is simple: insert a compatible adapter into the terminal's USB port. The system should automatically detect the new device. A notification about the new device connection will appear in the tray (top panel) or in the Wi-Fi settings. After this, the process repeats: scan for networks, select the SSID, and enter the password.
⚠️ Please note: Not all USB hubs are compatible with Wi-Fi adapters. For stable operation, we recommend connecting the adapter directly to the register port or using a powered USB hub with an external power supply, as the wireless module requires sufficient current.
- 🔌 Use adapters with an external antenna for better signal reception in metal cash registers.
- 💾 Drivers for most supported adapters are built into the Evotor firmware.
- 🔄 After connecting the adapter, you may need to restart the terminal.
- 📶 Avoid using USB extension cables longer than 1 meter without a signal booster.
Solving common connection problems
Even if you follow all the instructions, users may encounter errors. One of the most common situations is when the cash register sees the network but fails to connect, displaying the error "Obtaining IP address..." or "Authentication error." This is often due to the router running out of DHCP addresses. Solution: reboot the router or increase the range of addresses allocated in its settings.
Another common issue is time desynchronization. If the date at the checkout is out of sync, security certificates won't verify, and the internet won't work, even if Wi-Fi is connected. In this case, go to the date and time settings and enable the "Use network time" option. If there's no internet connection at all, manually set the time to approximately the correct value so the system can connect to the server.
A weak signal is another enemy of stability. If the cash register is located far from the router or behind shielding structures (metal racks, mirrors), the connection speed will be slow. This will lead to slow receipt processing. In such cases, use Wi-Fi repeater (signal booster) or switch to a wired connection via an Ethernet adapter if the cash register model allows it.
Checking connection quality and diagnostics
Once you've connected your Evotor cash register to the internet via Wi-Fi, it's a good idea to check the connection quality. Android's built-in tools let you see your link speed and signal strength. Go to the Wi-Fi settings, tap the connected network, and view the details. The connection speed should be at least 10-15 Mbps for comfortable operation, although the cash register consumes a small amount of data.
For a more in-depth diagnosis, you can use Wi-Fi analysis apps (such as Wi-Fi Analyzer) available in the Evotor Market app store. They will show channel congestion. If your router is running on a channel shared with 10 other neighboring networks, you'll experience constant packet loss. Switch the router to a free channel (1, 6, or 11) through its web interface.
It's also worth checking whether your antivirus or firewall software is blocking the ports required for your cash register software and fiscal data operator (FDO). Cash register applications typically request the necessary permissions upon first launch, but on strictly corporate networks, additional configuration may be required.
What should I do if the cash register displays "No internet connection" even though Wi-Fi is connected?
Check your date and time settings—this is the most common cause. If the time is off, the security certificates won't work. Also, try switching the DNS in your Wi-Fi settings to public (8.8.8.8). In rare cases, a full factory reset of the cash register can help.
Is it possible to share internet on Evotor from a phone?
Yes, this is a possible temporary solution. Enable a hotspot on your smartphone. However, keep in mind that mobile internet is less stable and has data limits. For permanent store operation, it's better to use a wired internet connection and a router.
Does Android version affect Wi-Fi network support?
Yes, older versions of Android may not support the new WPA3 encryption standards. If you have a modern network, try temporarily enabling compatibility with legacy devices in your router or use a guest network with WPA2.
How can I find the MAC address of a cash register for whitelisting on a router?
The MAC address can be found in the menu Settings → About device → Status or on a connected Wi-Fi network. It looks like a set of characters separated by colons (for example, 00:1A:2B:3C:4D:5E).
