General network recommendations
In general, you can utilize both Wi-Fi or Ethernet connections for your POS devices and terminals. However, we strongly recommend using Ethernet as it provides a far more stable and reliable solution for both the POS system and payment terminals. A wired connection helps minimize the risk of network interruptions, ensuring smooth and uninterrupted transactions.
Ethernet requirements
To connect your POS devices via Ethernet, ensure your access point meets the following requirements:
Megabit Ethernet (or higher)
Proper cables to match Ethernet speed (Category 5 or higher)
Wi-Fi requirements
To connect your POS devices via Wi-Fi, ensure your access point meets the following requirements:
802.11ac (Wi-fi 5)
Supports WPA/WPA2-Enterprise or WPA/WPA2-Personal encryption
Operates on 2.4GHz or 5GHz (preferred) frequencies
Please note that when the terminal or POS device shows it’s connected to your Ethernet, it doesn’t always guarantee an internet connection, as there may still be issues between your network and the internet
Allowlisting for restricted networks

Everyone using Kanpla → Kanpla admin, app and POS
Card payments with Adyen terminals → Adyen payment terminals
Card payments with FreedomPay terminals → FreedomPay payment terminals
Kanpla Signage screens → Kanpla Signage
Elo devices managed through EloView → EloView
