Ping without access point association

Hypothetical situation here: Is there a way to ping a computer with a known IP and subnet without being on the same LAN.

For example, Computer A is attached to an access point and is granted an IP of 192.168.5.202 with a subnet of 255.0.0.0. Computer B is not associated with the access point.

Is it possible for Computer B to set a static IP and subnet and broadcast a ping to Computer A (or something of the like), all without actually associating with the access point?

Re: Ping without access point association

If I understand what you are asking. No.

Now, if computer B is part of a subnet that is not part of the wireless access point's subnet, and there is routing between the two subnets, and they are part of the same private network (They don't have to go out on the public Internet), it may be possible -- if you have everything set correctly.

What I think you are asking is -- if computer B is not part of any network, and you set an IP and a subnet mask can you talk to computer A.  Definitely not.
