A modern retail outlet is unthinkable without a stable internet connection, which ensures the transfer of fiscal data to the OFD and EGAIS. Cash register Atol 91F It's one of the most popular solutions for small businesses due to its autonomy and reliability. However, for the device to function correctly online, the initial configuration of the wireless module must be performed correctly.
Connecting to a local network requires careful attention, as incorrectly entered parameters can lead to fiscal errors or the inability to process a receipt. In this article, we'll cover all the setup details. wireless interface, starting from the choice of method and ending with checking the connection with the server.
Successful network integration allows the cash register to automatically update the time, transmit receipts to customers via SMS or email, and instantly send data to the fiscal data operator. Ignoring this step will make it impossible to conduct legal trade in accordance with current legal requirements.
Preparing to set up a wireless connection
Before changing network settings, make sure you have access to the Wi-Fi hotspot and know its password. You will also need a utility Test KKM or Cash register driver, installed on the computer or laptop that will be used to configure the cash register.
It's important to check the device's battery status. The setup process can take time, and a sudden power outage will interrupt the configuration recording. The battery should be at least 30-40% charged for stable operation.
There are several ways to activate the communication module, but using a wired connection to a PC via USB is considered the most reliable. This ensures that the command will be accepted by the device even if there are issues with the old network settings.
Select a connection method: USB or Bluetooth
Users often wonder which interface to choose for initial setup. Although the model 91F Although the module supports Bluetooth control, it's preferable to use a cable for initial Wi-Fi module configuration. This is because Bluetooth drivers may interfere with the network discovery process.
- 🔌 USB cable ensures maximum stability of command transmission and does not depend on the battery charge at the time of data exchange.
- 📶 Bluetooth convenient for mobile work, but may require pairing every time you change operators or reboot.
- 🖥️ Ethernet (via docking station) Suitable for stationary points, but does not solve the problem of setting up a Wi-Fi module inside the cash register.
If you plan to use your cash register in a mobile retail environment where wired internet access is unavailable, setting up Wi-Fi becomes critical. In a brick-and-mortar store, you might consider using an Ethernet adapter if your cash register model supports it via a docking station, but the built-in Wi-Fi module is universal.
Setting up via the Test KKM utility
The most common configuration method is using the standard utility Test KKM, which comes with the drivers. After connecting the cash register to the computer and selecting the appropriate port in the program menu, go to the device properties.
In the properties window, find the tab responsible for network settings. It's usually labeled "Network" or "Wi-Fi." Here you'll need to select the operating mode. For most use cases, the "Network" mode is suitable. Infrastructure (Client) that allows the cash register to connect to an existing router.
⚠️ Important: Do not select Ad-Hoc mode unless you are creating a direct connection between two cash registers without a router. This will result in a loss of internet access in a typical retail location.
After selecting the mode, click the network search button. The utility will scan the air and display a list of available access points. Select your network from the list and enter the password. Pay attention to the capitalization and keyboard layout.
☑️ Check before saving
Configuration via the KKT Driver
A more advanced tool is the program Cash register driver (versions 4.x and higher). It provides advanced access to settings. fiscal storage device and peripherals. Launch the program and log in as the head cashier or administrator (the default password is often 30 or 44, but it's best to check the instructions).
Go to the KKT properties and find the "Wi-Fi Settings" section. The interface here may differ from Test KKM, but the basics remain the same. You need to activate the module, select a network, and enter the security key. The advantage of the driver is that it allows you to immediately test the connection without closing the settings window.
Some software versions offer a WPS feature. If your router supports this technology, you can press the WPS button on the router and initiate the connection in the driver. This simplifies password entry, but is less secure in terms of network perimeter protection.
| Parameter | Importance for home/office network | Value for open point |

Solving common connection errors
Even if you enter the correct data, the cash register may not connect the first time. A common issue is incompatibility with security standards. Older router models may use encryption. TKIP, while modern modules in Atol 91F require AES.
Another common mistake is frequency separation. A router may broadcast a network on both 2.4 GHz and 5 GHz frequencies under the same name. A cash register only supports the 2.4 GHz band. If your router combines networks, try temporarily separating them in the router settings or creating a guest network for only 2.4 GHz.
What should I do if the cash register sees the network but doesn't connect?
Try changing the broadcast channel on your router. Cash registers may not work correctly on channels 12 and 13. Set a static channel from 1 to 11 in your router settings.
It's also worth checking MAC filtering on your router. If a whitelist of devices is enabled, the cash register's MAC address (indicated on the label below or in the configuration text) should be added to the allowed list. Otherwise, the router will reject connection requests.
Checking the connection and diagnostics
After saving the settings, you need to verify that the cash register has indeed received an IP address and is connected to the global network. In the cash register test, run the "Test server connection" command or view the configuration report. The report should show an IP address other than 0.0.0.0.
For a more thorough diagnosis, you can use ping. Connect the cash register and computer to the same network and try pinging the cash register address from the PC, or vice versa, if the driver functionality allows sending network requests. A successful response will confirm a physical connection.
⚠️ Warning: If the cash register loses Wi-Fi settings after rebooting, the internal settings storage battery may be dead or there may be an error writing to the non-volatile memory. A firmware update or battery replacement is required.
Checking the time is an important step. When connected to the internet, the cash register should automatically synchronize the time. If the time is out of sync, the fiscal storage device may become blocked or receipts may be sent with the wrong date, resulting in fines.
Frequently Asked Questions (FAQ)
Is it possible to set up Atol 91F for Wi-Fi without a computer?
You can't configure Wi-Fi manually, using only the cash register menu. External software (KKT Driver or Test KKM) is required on a PC or smartphone (via the Atol Kassa app and a Bluetooth connection for parameter transfer).
The cash register doesn't see my Wi-Fi router, what's wrong?
Most likely, your router only operates in the 5 GHz band or is using a non-standard channel (higher than 13). Switch your router to mixed mode (b/g/n) and set the channel to 1-11.
How do I reset the network settings at the checkout?
In the cash register driver's properties section, there's a "Reset network settings" button, or you can run the initialization command with the reset flag. This will return the parameters to factory defaults.
Do I need a SIM card for Wi-Fi to work on the Atol 91F?
No, a SIM card is only required if you use a 3G/4G modem. Wi-Fi does not require a SIM card; the cash register uses your router's internet connection.
