Sounds like you've a subnet mask mismatch on the network perhaps. The message comes from your own PC because it believes you are on the same subnet as the device you are trying to ping and it doesn't need to route to another host to reach the IP. it should establish the mac address associated with the target machine via ARP. The message you are getting is saying it can't do that. You've obviously got connectivity to your default gateway which is what is routing traffic to the internet etc. Check the subnet mask is consistent on all the networking equipment. Most likely this is 255.255.255.0 The other possibility is you've enabled a feature on your Router/switch that has isolated your PC from the rest of the network. This is called Private VLAN or port isolation https://en.wikipedia.org/wiki/Private_VLAN I haven't experience in the particular brand you have so I don't know if this is something it supports and if it does if it is something that it has given a stupid nonstandard name to.
