hey everyone. ive got what i think is a pretty interesting question here. i have a linksys wireless router which does not have the generic linksys ssid, but it is unsecured. i am planning to secure it but i am not ready yet as i am still tweaking some other things with the router and my computers. anyways, i have a neighbor who keeps logging onto my router, even after i check the dhcp log and delete them. they just reconnect a little while later after ive kicked them off. my question is this: i would like to send them a friendly message but i cannot figure out how to. i am familiar with the basics of netsend but as far as i know, to use netsend the computer has to be in the same workgroup. is this correct? if so, is there a way that i can find their workgroup or even send them a message without sending them a message? lastly, if they have netsend disabled on their computer is there a way that i can send a message by another means? i know that this is a pretty interesting question, but i would just like to be able to send them a message, nothing harsh, before securing my network so i would greatly appreciate any help. thanks in advance. note: i posted this message in two forums on techspot because i wasnt sure of the right one to use.
