I'm trying to send a message to one of the neighbors by connecting to his wireless router (*Open - No security*) and notice him to "Put a password on the router!".

I find his IP `192.168.1.2` and mine is `192.168.1.5` ( for now ), I can ping him, default gateway ip is `192.168.1.1`.

I'm running win XP which I can use `msg 192.168.1.2 hi guy!` command but it says:
`192.168.1.2 does not exist or is disconnected`

I also tried `net send` with no success `net send 192.168.1.2 hi guy!`:

```
An error occurred while sending a message to 192.168.1.2.
The message alias could not be found on the network.
More help is available by typing NET HELPMSG 2273.

```

Also `net view` command just displays me on the network.

helps needed.
