If you can't, then you may want to plug directly into the ISP provided modem and see if you can receive a dynamic IP address and ping from there. How to Resolve ICMP Hardware Error Message If the Ping packet couldn't reach the destination network, you will get destination net unreachable error message.

Does anyone know why the program works fine in the command prompt but doesn't work as a batch? Unknown packet type Performance Using the ping and traceroute commands, we obtain the round-trip time (RTT). The first router, in this case Router2 (126.96.36.199), drops the packet, and sends back to the source (188.8.131.52) a type=11 ICMP message. Do I need to do this?

As long as the corresponding MAC address is not in the ARP table, the ping fails as a result of "encapsulation failed". If a packet count and deadline are both specified, and fewer than count packets are received by the time the deadline has arrived, it will also exit with code 1. N(e(s(t))) a string How do I replace and (&&) in a for loop? You can check the the input drops with the show interface command.
How common is the usage of yous as a plural of you? When a packet destination is the router itself, this packet has to be process-switched.
