Issue: The ICMP check is not working after configuration. When click "Host/IP Check"button, it displays "the Host/IP is Error" or "Opps! The Host/IP assigned can not get through. Please check your router is online, and the SIM card is with balance for network surfing." However, the connected PC can go internet or privacy networks.
