DELL Latitude 7400 Intel Cannon Point-LP CNVi [Wireless-AC]

Lately on-boarded a new laptop DELL Latitude 7400 where I’m facing frequent service (internet) disruption where it’s connected over the Wifi network WPA2, Enterprise connection.

At the time of service failure, logs captured are as below:

Till NetworkManager service restart internet service remains down.

Any relevant issue reported or already in the knowledgebase or any clue about it?
