Hello Kishore,
In this test of yours, did you notice how much data was consumed?
Was your sim card data package was enough?

I am also facing similar issue on WP7608-1, after certain time and amount of data consumed, say 50min or 500+MB , the cellular connectivity drops, and then it does not resume until, I reboot the GSM module.

One the module is rebooted and connection is established it resume ping and web page loading.

what is the return of AT!GSTATUS? when connection drops?
Did you try the latest FW?
