DX3301-T0 Can't detect DSL connection after upgrade firmware.

alexrad

I bought the router in 2022. How many months is the warranty? Yesterday, after flashing the router to the latest ABVY.4 firmware, the connection was lost.
Rollback to the old firmware did not work. The Internet light (DSL) does not light up at all.

I suggest that you can ask your service provider or retailer for assistance.

Hello @alexrad

Thanks for your post.

Can you say please what LEDs are lit on your DX3301-T0 ?

The user guide available at https://support.zyxel.eu/hc/en-us/articles/5858783065362-User-Guide-AX-DX-PX-3301-T0-Serie-V5-13-5-50 has the following table in it:

If the Power LED is lit Green, then are you able to check the configuration of your Broadband connection?

Kind regards,

Tony
