Recently, we've received a lot of feedbacks that many of our clients can't access the internet with their Cudy routers, despite their SIM cards being functional and their APN settings being accurate.
Here is a method we have discovered that could help with the issue.
Step 1: Update the router to the lastest firmware version.
If the firmware is already the latest version. You can skip this step. If not, Please download and unzip the official firmware.
Open a web browser and go to http://cudy.net or http://192.168.10.1, Then log in. For details, please refer to How to log into the web interface of Cudy Router?
Upgrade the firmware in Advanced Settings->Firmware.

Step 2: To download and upgrade the module firmware, please contact support@cudy.com to obtain the upgrade firmware. At the same time, download the Diagnosis bin file in Diagnostic Tools->Diagnosis->GO->Download and send the file to the support.
Step 3: Enter the address below in the address bar. Upgrade the firmware as video shows.

Step 4: When the update is complete, it will return to the System Status. Go back to the hide Firmware Upgrade page and check if it's successful.
If the problem persists, go to Diagnostic Tools->Diagnosis->GO->Download and send the bin file to support@cudy.com.

@Dear Francisco,
Please install the SIM card on your phone and check if the SIM card is out of money?
“My LT400 V2 router has suddenly stopped working without being bumped or turned off. Diagnosis returns me “4G has obtained the IP address but cannot access the Internet” and “DNS is abnormal”. I have tried resetting it, firmware upgrade”

@Lieber Stef,
1. Ist Ihre SIM-Karte im Rückstand (kein Geld mehr vorhanden)? Sie können die SIM-Karte in Ihr Telefon einlegen und prüfen, ob es sich mit dem Internet verbinden kann?
2. Versuchen Sie bitte, die Firmware des Routers zu aktualisieren und überprüfen Sie das.

Hey, seit heute habe ich bei meinem Cudy Router LT500D V2.0 die Meldung “DNS abnormal”, gibt es dafür eine Lösung? Vorher lief es ohne Probleme.
Mit freundlichen Grüßen

“TENGO UN LT400 Y DESDE EL PRIMER DIA NO HA FUNCIONADO CORRECTAMENTE. AHORA QUE DESEO RESETEARLO A VALORES DE FABRICA Y ACTUALIZAR EL FIRMWARE NO PUEDO PORQUE NINGUNO ES VÁLIDO, TODAS LAS ACTUALIZACIONES ESTAN INVADIDAS. PARA REMATAR EL TEMA LEO EN EL BLOG QUE DEBO PONERME EN CONTACTO CON SU SOPORTE PARA SOLUCIONARLO, INCREIBLE. VOY A BUSCAR ALTERNATIVAS PORQUE NO ME GENERA CONFIANZA EL ROUTER Y EL FABRICANTE”
