Android devices cannot connect to the WiFi

Aurélien

Hey Zyxel Team,
We are facing an issue with 3 payment terminals(Android devices).
Each device cannot connect to the WiFi: it shows "saved" beside the SSID but it doesn't connect. 
When I click on connect, it briefly shows "connecting" and then "saved".
Any recommendations, or experiences with similar issues?
I compared it with another installation with the same setup and it works.

I tried to disable/enable 2.4GHz or 5GHz to see how it reacts without success.
There are no MAC address filters.
We can connect iPads and laptops to this network but not those 3 terminals.

Hi @Aurélien ,

If other clients are successfully connecting to the SSID but Android devices are having trouble, please consult this article for troubleshooting guidance.
