As specified for all Konyks devices you need a 2.4Ghz wifi network
Also pay attention to the Wi-Fi security protocol, you must choose the WPA2-PSK / AES mode
(setting in the interface of your internet box or router)
If you have difficulty connecting in EZ mode, do not hesitate to try the QR Code mode which works with great reliability. With the Livebox it is sometimes necessary to deactivate the firewall. You can reactivate it after installation. Temporarily disabling the firewall during setup would allow you to spend much less time.
