Modern POS terminals require a stable connection to conduct transactions, and the transition to wireless technologies is becoming the industry standard. Model The Verifone VX675 is one of the most popular devices in the manufacturer's lineup that supports networking. WLANHowever, initial setup or changing network parameters often causes difficulties for retail administrators and cashiers.
The configuration process isn't as complicated as it seems at first glance, but it does require careful data entry. A single character error in the password or an incorrect encryption type will prevent the device from connecting to the acquiring bank. In this article, we'll detail each step required to successfully connect your terminal to a hotspot.
Before tinkering with the software, make sure you have access to the router and your network settings. You'll need the exact network name (SSID) and the current security key. Without this information, accessing the settings menu will be useless, as the terminal won't be able to authenticate to the provider's infrastructure.
Equipment preparation and compatibility testing
The first step should always be a physical inspection of the device and surrounding infrastructure. Make sure the battery The Verifone VX675 should be at least 30-40% charged, as the process of searching for a network and establishing a connection consumes significant power. If the battery is low, connect the device to a power outlet using the original adapter.
Next, you need to check the compatibility of frequency ranges. Model VX675 Most of its modifications support the standard 802.11 b/g/n in the 2.4 GHz range. Modern routers often operate in two bands (2.4 and 5 GHz), and the terminal may simply "not see" the network if it broadcasts only at the 5 GHz frequency.
⚠️ Note: If your router uses the "Smart Connect" feature (combining 2.4 and 5 GHz networks under a single name), the terminal may operate unstable. We recommend separating the networks in your router settings and connecting the POS system to the 2.4 GHz network.
It's also worth finding out in advance the type of encryption your access point uses. The most common and recommended security standard is WPA2-PSK or WPA3Legacy encryption methods, such as WEP, may not be supported by new firmware versions or, conversely, may be the only supported option in very old configurations, creating security risks.
Logging into the terminal administrator menu
To access system settings, you need to exit teller mode. On the waiting screen, which usually displays the bank logo or the word "Waiting," you need to press a special key combination. Most often, this is the sequence 0 + 0 or F + 0 + 0, but the exact combination depends on the installed firmware and the requirements of the acquiring bank.
After entering the combination, the device will ask for the administrator password. By default, devices Verifone frequently used code 166661 or 123456If these codes don't work, please contact your processing company's technical support, as the password may have been changed remotely.
- 🔑 Enter the key combination to open the setup menu (usually 00).
- 🔢 Enter the administrator password (default 166661).
- 📱 Wait for the main menu to appear with the options "Settings", "Communications" or "Admin".
- 🔍 Select the item responsible for communication settings (Communication Settings).
The menu interface may differ depending on the operating system version. MX OS or GEOSNavigation is carried out using arrows and function keys. F1-F4, the functions of which change dynamically and are displayed at the bottom of the screen.
Searching and selecting a wireless network
After successful authorization in the administrator menu, go to the section Communication or ConnectivityHere you need to find the subsection responsible for wireless connections. It may be called WLAN, WiFi or Wireless LAN. Activate the module if it is in the off state.
Start scanning for available networks. The terminal will begin searching for signals within range. The list may refresh for a few seconds. Find your network name (SSID) in the list. If the network is hidden (Hidden SSID), you will need to enter the name manually by selecting "Add Network" or "Manual Setup."
When choosing a network, pay attention to the signal strength indicator. For stable payment processing, a signal strength of at least -70 dBm is recommended. If the signal is weak, transactions may be delayed or terminated during receipt printing, which is critical for businesses.
Entering security parameters and keys
After selecting the desired network, the terminal will request security settings. In most cases, the encryption type is WPA2-PersonalIn the window that opens, you must enter your WiFi password. Be extremely careful: the terminal keyboard input interface is specific, and case-sensitivity (uppercase/lowercase) is important.
To enter special characters or switch case, use the function keys indicated by on-screen prompts. After entering the password, the system will prompt you to save the configuration. Be sure to check the characters you entered before confirming.
⚠️ Note: Some corporate networks use WPA2-Enterprise encryption with domain user login and password. Standard POS terminals often don't support this mode without special certificate configuration.
If your network uses a static IP address, you'll need to go to TCP/IP settings and manually enter the IP address, subnet mask, gateway, and DNS servers. In DHCP mode, the terminal will automatically obtain this information from the router.
☑️ Checking WiFi settings
Connection testing and diagnostics
After saving the settings, the terminal will attempt to establish a connection. A successful connection is usually indicated by the appearance of a WiFi icon at the top of the screen, along with a signal strength indicator. However, the visual presence of the icon is not enough—you need to verify the channel's functionality.
The communications menu often features a "Test Connection" or "Ping" option. Run the test. The device will send a request to the acquirer's server or the specified IP address. A successful response confirms the route has been created correctly.
| Parameter | Normal value | Critical value |
|---|---|---|
| Signal level | -40... -65 dBm | Below -75 dBm |
| Response time (Ping) | < 200 ms | > 1000 ms |
| Packet loss | 0% | > 5% |
| IP status | Received (DHCP) | 0.0.0.0 |
If the test fails, check whether your router's firewall is blocking the ports required for the terminal to operate. These are typically ports for SSL/TLS connections. You should also ensure that your router hasn't reached its maximum number of connected clients.
Solving common connection errors
One common problem is a reconnection loop, where the terminal constantly tries to connect but keeps dropping the connection. This can be caused by incompatible security standards or a glitch in the WiFi module. In this case, a full reset of the network settings can help (Network Reset) and reconfiguration from scratch.
Another common error is "Authentication Failed." This means the terminal found the network, but the password was rejected. Check your keyboard layout: you may have entered the letter "l" (el) or the symbol "!" instead of the number "1" (one).
What to do if the terminal freezes at the "Connecting..." stage
Try removing the battery for 10-15 seconds to fully reboot the modules. If this doesn't help, AP Isolation may be enabled on your router, which prevents devices on the same network from communicating, blocking the terminal.
If the problem is systemic and affects all devices on the network, the terminal firmware itself may need to be updated. Verifone VX675New software versions often contain fixes for wireless module drivers.
Save configuration and exit
After a successful connection test, be sure to exit the admin menu correctly. This is usually done by pressing the red button. Cancel Several times until you return to the main screen, or by selecting "Exit" or "Logout." Simply turning off the terminal with the power button is not an option at this point, as the settings may not have time to be written to permanent memory.
Make sure the network activity icon appears on the main screen. Conduct a test transaction for a minimum amount or generate a Z-report to fully verify the stability of your connection to the bank.
Record the new settings in your point-of-sale equipment change log. This will help you quickly restore the system to working order in the future if you replace your router or experience a power outage.
Is it possible to use open WiFi without a password?
Technically, it's possible to connect, but it's strongly recommended not to use open networks for financial transactions. Data on such networks is transmitted unencrypted (or with minimal protection), making it vulnerable to interception. Acquiring banks may block terminals operating through suspicious communication channels.
Why doesn't the terminal connect to the 5 GHz network?
Most models Verifone VX675 Equipped with Wi-Fi modules that operate only in the 2.4 GHz band, they physically cannot "see" a network operating exclusively at 5 GHz. You must configure the router to operate in mixed mode or assign a separate SSID for 2.4 GHz.
What to do if you forgot your administrator password?
Resetting the administrator password on Verifone terminals often resets all settings and encryption keys (TMS/EMS). Restoring access usually requires contacting a service center or bank, as they may need to download new encryption keys for secure data transfer.
