Internet stopped working immediately after the firmware upgrade. Since this version has no rollback feature, unable to downgrade the firmware, 

 

Please let me know the possible solution

 Hi  @Joseph-TP 

 

Thanks a lot for your quick revert. 

After upgrading firmware version to 1.3.1 and a factory reset, the issue seems to be resolved and I am able to connect to the internet. 

 

Without factory reset, it was giving the message as Internet port disconnected or Cable not connected. 

 

Regards

Deepak
