A modern retail outlet is unthinkable without stable internet access, especially when it comes to fiscal storage devices, which are required to transmit data to the fiscal data operator (OFD) in real time. Atol 91F Wireless modules are among the most popular devices on the market, but their initial setup often raises questions for entrepreneurs without in-depth technical knowledge. Activating a wireless module isn't complicated, but it does require attention to interface details and the correct sequence of actions.
In this article, we'll cover not only the standard activation procedure but also common errors users encounter when trying to sync their cash register with their router. You'll learn how to enter passwords correctly, where to find the MAC address for whitelisting on corporate networks, and what to do if the drivers don't recognize the device. Connection stability - this is a guarantee of no queues and no fines from the tax authorities.
It's worth noting that cash register software may have different firmware versions, which sometimes affects the layout of menu items. However, the operating logic network settings The Sigma OS family remains the same. Before starting, make sure you know the exact name of your network and its password, as the system does not save erroneous data for retry without your intervention.
Preparing to set up a wireless connection
Before proceeding directly to the settings menu, you must ensure that the equipment is physically ready for operation. Cash register Atol 91F The device must be charged or connected to a power source, as it may consume more power than usual while searching for networks and logging in. It's also critical that the router you plan to connect to operates in the 2.4 GHz band, as this cash register model typically doesn't support the 5 GHz standard.
Make sure you're in an area with a strong signal. Walls with metal reinforcement or microwave ovens can cause interference, which can lead to unstable operation of the fiscal registrar. If you're using a corporate network with MAC address authentication, prepare this information in advance so you can add the device to the administrator's authorized list.
⚠️ Attention: If you use a SIM card for tethering, make sure it doesn't have a PIN. Cash registers Athol often do not have an interface for entering a PIN code when connecting to a mobile phone hotspot, which will lead to an authorization error.
Also, check that the date and time on your device are correct. An inconsistent time can cause errors when attempting to connect to the OFD servers immediately after connecting to Wi-Fi, even though the network itself may be functioning correctly. To check, go to the system settings and compare the readings with the reference time.
Entering the Sigma OS settings menu
Operating system interface Sigma, on which it is based Atol 91F, is built using large tiles, making navigation easy. To get started, unlock your device if it's locked and go to the home screen. Here, we're interested in the section responsible for system settings.
Find and click on the tile or icon with the name Settings (often symbolized by a gear). In the list of options that opens, select Network and Internet or simply Wi-Fi, depending on the firmware version installed. This is where the wireless module switch is located.
If you don't see the Wi-Fi icon on the home screen, it may be hidden in the "System" or "Service" folder. In some configurations, access to the full settings menu may be restricted by user rights. In this case, you'll need to log in to administrator mode or use specialized service software from your computer.
Where can I find the service menu?
The service menu on Atol cash registers is often hidden. Accessing advanced network settings sometimes requires pressing and holding a specific key combination or entering an access code provided by technicians when purchasing the equipment.
Finding and connecting to a Wi-Fi network
After entering the appropriate section of the interface, the first thing you need to do is activate the module itself. Move the slider to the position OnThe device will begin scanning the surrounding area and, after a few seconds, display a list of available wireless networks. Your router should appear on this list.
Find your network name (SSID) in the list. If the network is hidden, select the option Add a network and enter the name manually. Selecting a network from the list will open a password entry window. Please note: the system is case-sensitive and keyboard-sensitive. Use the language switcher if the password contains letters.
After entering the password, click the button ConnectThe connection establishment process can take 5 to 15 seconds. During this time, the cash register exchanges handshake packets with the router. A successful connection will be indicated by a beep and the appearance of a signal strength icon in the screen's status bar.
☑️ Connection algorithm
⚠️ Attention: When entering your password, pay attention to hidden characters. Some software versions have a "Show Password" button (an eye), which allows you to visually check the entered characters before sending data to the router.
Setting up static IP and DNS
In most cases, the cash register will automatically obtain an IP address via DHCP. However, in complex corporate networks or when using specific routers, manual configuration may be required. To do this, find the item in the menu for the selected network. Additionally or Advanced settings.
Here you can change your IP settings Dynamic (DHCP) on StaticYou'll need to enter the IP address, subnet mask, gateway, and DNS servers. This information is usually provided by your system administrator or listed on the router's sticker (for the gateway). Entering the gateway incorrectly will result in no internet access, even if the connection to the router is established.
Particular attention should be paid to DNS servers. Using public DNS, for example, from Google (8.8.8.8) or Yandex (77.88.8.8), can improve the response speed of the cash register when checking fiscal storage devices and sending receipts to the OFD if the provider provides unstable name servers.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP address | Unique address of the cash register on the network | 192.168.1.150 |
| Subnet mask | Determines the size of the network | 255.255.255.0 |
| Gateway | Router address for Internet access | 192.168.1.1 |
| DNS 1 | Primary name server | 8.8.8.8 |
Drivers and PC operation: cash registers and COM ports
Once the Wi-Fi at the cash register is enabled, it is often necessary to configure its connection with a computer or laptop to forward a test receipt or register it in the fiscal drive. To do this, the PC must have Cash register drivers from the company Atol. Without them, the computer won't recognize the cash register either via USB or over the network.
You need to add a new device in the KKT driver properties. Select the connection type Over the networkIn the IP address field, enter the address assigned to the cash register (you can see it in the Wi-Fi connection status on the cash register screen). The standard port is usually used. 5555 or 7777, but it’s better to check this in the documentation for a specific firmware version.
If the driver doesn't see the cash register over the network, check your Windows firewall. It may be blocking incoming connections from the COM port emulator. Also, make sure the PC and cash register are on the same subnet. For example, if the cash register address is 192.168.1.150, and at the computer 192.168.0.10, they will not see each other without routing settings.
⚠️ Attention: Antivirus software on your computer may block cash register drivers, considering their network activity suspicious. If you experience connection issues, try temporarily disabling the firewall or adding the driver to the exceptions list.
Diagnostics and problem solving
Even with the correct settings, problems may still occur. If the cash register displays "Connected, no internet access," the problem is most likely with the router or internet provider. Check if the internet is working on other devices. If the network is working, try a full power cycle: turn off the cash register, wait 10 seconds, then turn it back on.
A common issue is time desynchronization. The cash register may connect to Wi-Fi, but it won't be able to send a receipt if the device's time is significantly different from the actual time. Enable this option in the date and time settings. Use network time (NTP) so that the cash register synchronizes automatically when connected.
If your connection keeps dropping, check your Wi-Fi channel. If your router is on a congested channel (for example, in a shopping mall), the connection will be unstable. Access your router settings (via a browser) and change the channel to a less congested one (1, 6, or 11).
What should I do if my cash register can't see the 5 GHz network?
Series cash registers Atol 91F They are equipped with Wi-Fi modules that operate primarily in the 2.4 GHz band. They are physically unable to detect 5 GHz networks. You will need to either enable a 2.4 GHz guest network on your router or separate the SSID so that the cash register can connect to the appropriate band.
How do I reset my network settings to factory defaults?
If you're confused about your IP settings or have forgotten your network password, you can reset your network settings. In the Wi-Fi menu, find the "Forget Network" option for a specific access point, or perform a full network reset in the system menu. This won't affect your fiscal data.
Why does the cash register driver say "No connection"?
This means the PC can't reach the cash register at the specified IP address. Check to see if the cash register's IP address has changed (unless a static one is used), if your antivirus software is blocking the connection, and if the "Network Connection" option is enabled in the cash register's settings under "Services" or "Driver Settings."
