Airtel — 4g wifi dongle showing no internet

Address:

411020

I have been using airtel wifi 4g dongle for last few months. But from last few days it has stopped connecting to internet.
My laptop and phone can connect to the dongle but show no internet message.
I have paid the bills for the connection promptly without delay.

Wifi hotspot number is [protected].
