Description

How to set up Ethernet or Wi-Fi network connections on a PAX payment terminal and troubleshoot connection issues

What's in this article?

Terminals can connect to your router with an Ethernet cable or through Wi-Fi. The system works best with an Ethernet connection in your store. If you are using a Wi-Fi connection, we highly recommend using a Wi-Fi that is dedicated to your business and ensuring your connection is configured for privacy. Your wireless router manufacturer should have provided instructions for ensuring appropriate setup. 

NOTE
Dial-up connection via a phone line is not supported.

Enable wired Ethernet

If your terminal has an Ethernet port, connecting the terminal to your internet router using an Ethernet cable is the recommended option. 

To connect the Ethernet cable

For some devices, the Ethernet port connections are located on the charging base.

Having trouble connecting to Wi-Fi?

If you are having trouble connecting to Wi-Fi, try the following first: 

  • Check that the Wi-Fi icon is visible and Wi-Fi connection is enabled, then try the transaction again. 
  • Power cycle the terminal and try the transaction again. If Wi-Fi is connected after the terminal is already powered up, the terminal should detect the connection upon the next communication attempt and does not require power cycle.
  • Ensure the security protocols for your router are set to WPA or WPA2. You cannot use the older WEP or WAP formats.
  • Ensure your terminal is connected to a secured network that requires a password. Unsecured networks will not appear in the available networks list and a terminal will not connect to an unsecured network.

If you still are having trouble, some common troubleshooting scenarios are provided below:

Wi-Fi network does not appear 

If your Wi-Fi network does not appear in the available networks list, see below:

  • If your network is not secured, it will not appear as an available network.
  • Ensure that an Ethernet cable is not connected to the payment terminal. 
  • Your PC or laptop should display a list of all available local wireless networks. If your wireless network doesn't appear after several minutes, verify that you are in range of your router or modem by moving closer to the device.
  • If you are using a hotspot, ensure that your hotspot is connected to the cellular network.
  • If your network is secured and still doesn't appear, disable and re-enable your wireless network adapter:
    • Look for your laptop or MacBook's Network Adapter on/off switch and switch it to off, wait a few seconds and switch it back on.

      NOTE: If you cannot find the switch or are using a PC, go to the Windows device manager and turn the wireless network adapter off and then turn it back on.

    • If using a hotspot, switch the hotspot off and on again.
  • If your wireless network is secured and still does not appear, your wireless router may be configured to not broadcast a network name. If so, follow the directions provided by your laptop or PC for manually adding a network to your list of preferred networks.
Wi-Fi network appears but will not connect

If you can see the name of your wireless network on your list of available networks but are having trouble connecting:

  • Confirm that the name of your network is entered correctly. Your router may have a sticker that lists the network name and/or password.
  • Make sure that you entered your password correctly. Most passwords are lengthy and a combination of uppercase letters, lowercase letters, numbers and symbols. 
  • If using an iPhone as a hotspot, ensure that you enter the dashes in the password.
  • Your wireless router may not be broadcasting at a frequency band that is compatible with the payment terminal or that doesn't work well for your environment. We recommend the 2.4GHz option in most cases. Change your router frequency band, following your router manufacturer's directions. 
    Terminal models, their hardware version and their supported Wi-Fi Bandwidth
    Payment TerminalHardware VersionSupported Wi-Fi Bandwidth
    A80V10 (deployed after 2022) The number 10 is printed on the paper cover, below the Contactless logo2.4 or 5 GHz
    A80V6 or V7 (deployed prior to 2022)2.4 GHz
    A920All2.4 GHz
    E700All2.4 or 5 GHz
    E800All2.4 or 5 GHz

    If needed, refer to your router manufacturer's support for additional assistance.

  • If your network and password are correct, but you still can't connect, try removing and reconnecting to the network
    Remove and reconnect network
    1. On the terminal, open Settings, entering the password when prompted.
    2. Tap Wi-Fi.
    3. Tap on your network name
    4. Tap Forget.
    5. Tap On toggle to turn off the Wi-Fi. 
    6. Power the terminal off and then back on again.
    7. Return to Settings and tap Wi-Fi.
    8. Tap On to turn on the Wi-Fi.
    9. Select and connect to a known network name with a confirmed password.
Try connecting to the Wi-Fi network with another device

If you are still having trouble, try connecting another device, such as a smart phone, tablet, or laptop, using the same password. If the second device won't connect, check that your Wi-Fi network is working properly and that your password is correct.

Verify that your Wi-Fi network modem and wireless router are working correctly

Verify that the power cord is connected and that all the device indicator lights on your wireless router and/or your modem are on as illustrated in the manufacturer's documentation.

If the indicator lights are not on or not blinking properly, you may have to reset your wireless router and/or modem as instructed in the manufacturer's documentation.

If you are using a hotspot, ensure that your hotspot is connected to the cellular network.

I forgot my password for the router, now what?

Reset your Wi-Fi password by connecting your computer directly to your wireless router and using your wireless router's "Web User Interface" as instructed in the manufacturer's documentation. Follow the instructions from the manufacturer for resetting the password.

Troubleshoot network issues

If you suspect that your internet connection is unstable, you can attempt a PING from the terminal to either your router or an outside server. 

To ping test a connection


  1. From the Payments (Payments P2PE) application, tap the FUNC tab.
  2. Tap Ping. URL and Ping Timeout(ms) fields will default. The Timeout(ms) value determines how long the app will wait before ending a connection test.
  3.  Tap Confirm. Ping Test results will display. The packet loss should say 0%. Lost packets indicate an unstable connection.
  4. Use the following table to troubleshoot the results of the ping test, then tap OK. issue and troubleshooting task.
