Zyxel USG Flex 100AX - problem with internet via Wi-Fi

mlik

Hello,

I have a problem with accessing the internet via Wi-Fi connection to the Zyxel USG Flex 100AX device. Fresh installation. when I connect to it wirelessly, I constantly have no access to the internet even though the connection with network seems to be ok. Restarting the WiFi on my macbook temporarily solves the problem. I don't know what is causing it. I have the standard settings. If I set the address statically (manually) the connection is ok. When connected via LAN and with a DHCP address, everything is also OK.

network settings

security mode: wpa2

cipher type: AES

Expiration time: 7200s

Group key update counter: 30000

Hi @mlik,

From the logs seems like your device left the SSID. Is this done by you?

May I know if you did the ping test when the issue happened? If yes, what's the result?
