Hi,
I upgraded my Zyxel SCR 50AXE to the latest version (V1.20(ACGN.0)), and after that, my 2.4GHz Wi-Fi network stopped working. Sometimes it appears, sometimes it doesn’t, and when I try to connect, it gives an error. It also shows a Wi-Fi network named “SSID,” but I think that was already there before the upgrade.
Has anyone experienced any bugs with this version?

Thanks in advance.

    Hi @Lau13

    I replicate this issue with V1.20(ACGN.0), but there's no issue. The SSID is visible and can connect to it.

    Could you share the error message with us so we can better check this issue? And what device did you use to connect? Please help to check its WiFi generation and share with us.

    The Wi-Fi network named “SSID,” is not the default SSID name of the SCR50AXE, therefore, it is more likely an SSID from other devices.

    Hi @Lau13

    I have similar issues with latest firmware for security routers, regarding WPA2 and old WiFi cards.

    Which devices are you trying to connecto to "old" 2.4 GHz band?
