Our Screenly Players support the following wireless networks and authentication types.
Raspberry Pi 3B - Supports 2.4GHz frequency range.
Raspberry Pi 3B+ - Supports dual-band 2.4/5GHz frequency range.
Currently, all of our players support WPA and WPA2-PSK (Personal) only. WPA2-Enterprise and/or 802.1X are currently not supported.
Note: We also recommend disabling any type of band steering feature your managed access point may have. Also, try to avoid using single SSID's that operate at both 2.4GHz and 5GHz. Instead, create a new SSID specifically for your Screenly players, that operates at either 2.4GHz OR 5GHz.
