Hello,
Could you please check what IP address you are getting on WAN ?
Please confirm if you are using both the mobile antennas ?
Could you try inserting a custom APN instead of keeping it on Auto .
Try searching for correct APN for your operator . Also if you keep APN on auto then change it to custom it would itself appear on the field and you can simply save .
Please let me know .
Thank you.
Have a nice day.
Regards,
Ahmed
