Improve this answer. Some things I would check. Finally, if nothing else works, try to ping 8. Without the ARP mapping, the ping frame can't be addressed at the If static ARP mappings fixes it, try temporarily turning off all wireless encryption, then delete your static ARP mappings and try your test again.
If ARP works this time, it's a sign that multicast is not completely broken on your DHCP uses broadcasts! In the other direction, they're usually unicast. And it's only in the to the client direction that multicasts are tricky in Check with your AP and client card vendor for firmware and driver updates. Always buy Wi-Fi certified Please also "name and shame" the vendors of the AP and client card s in question.
When multicast is broken between an AP and a client, I can't think of an easy way to tell if the fault is with the AP or the client, other than process-of-elimination, by seeing if other brands of wireless clients have the same problem on that AP, and seeing if that wireless client has the same problem on other brands of APs. The more advanced way to pin the blame on one end or the other is to use another machine that's not part of the test, but has an Someone well-versed in I do most of my networking work on Macs, so I can't walk you through getting Modify that if your AirPort card is not en1, or if your AP is not on channel 1.
The -c1 argument to the airport tool puts in the interface on channel 1; modify that to the channel your AP is on. Or you can run Wireshark, tshark, etc. Are you certain the firewall on this system is disabled? I've seen this behavior in Windows 7 when it isn't.
Otherwise, you could check your arp tables with arp -a to see if you have an entry for Well, the arp output isn't listing an entry for Is there a VPN or other security software involved here? Well, I was hoping that ipconfig shouted out something obviously broken, but it doesn't.
Can you ping other hosts on the network? Try How about other hosts in the world? My favorite to ping in 4. Ok, lets look at things from the other side.
The error message " Destination Host Unreachable ", during a ping test, tells that the ping request from our computer cannot find the route to the destination IP address destination host.
It means the packet sent from your computer reached the destination network successfully but the remote gateway failed to find the destination host. So the remote gateway sends an Echo message " Destination host unreachable ". One major possibility for this error is there is no route listed in the remote gateway, for the packet send from your computer, to destination host.
If there is no route available, it is impossible to find the destination host and your computer will receive an error message " Destination host unreachable " from remote gateway. So one of the reason for this can be faulty routing table. If the destination host is down at the time the packet send, it may result destination host unreachable error message.
