dnscheck n

This command is used to enable or disable the CTM gateway from checking for valid DNS IP addresses obtained from the carrier when it connects to the network. If the DNS IP addresses are invalid, the gateway will disconnect the current network connection and reconnect.

n = 0	Disable checking for valid DNS IP addresses from the carrier
n = 1	Enable checking for valid DNS IP addresses from the carrier (Default)

Notes:

After 5 reconnects have been attempted every 30 secs, and the gateway still gets an invalid DNS, the gateway will stop disconnecting and reconnecting the network connection.

Examples:

Disable checking DNS IP addresses from the carrier :
cmd dnscheck 0
