Hi!

Hello,

Thanks for reaching out!

Can you please go to the device’s CLI and login via root as a username and the password is the same as WebUI. And please run ping 8.8.8.8 command and share the output here.
And also can you please check the zone window. If the LAN → WAN connections seems okay?
I also attached the screenshot below.

Kind Regards,
Caner

Hello,

Your router has internet connection and there shouldn’t be any issue.
Can you please click edit on your WAN interface and change the PDP type to IPv4 only?

Maybe your devices is getting IPv6 address instead of IPv4.
After you change the configuration please reboot your device.

Please let me know about the result!

Kind Regards,
Caner
