How do i use this command? I believe someone nearby is using my network to access the Internet, on the account of my wireless signal's strange behaviour. Ive found out that their network isnt secure, and need to notify them. Also they need to change the name of their network on account of its name being the deafult of belkin54g.

Uh? Sounds like it's your network that is insecure rather than theirs.

If your WLAN is set up correctly then noone will be using it (unless they're determined hackers which is very unlikely)
A poorly confirgured WLAN on his side will not be giving him access to yours.

If his is insecure, why worry about it? It's their own responsibility.

1.) You should only be allowing defined MAC addresses.
2.) You should turn "broadcast" off.
3.) Make sure you impliment encryption of whatever type. (WPA preferably)

For a home wireless setup that should be enough, very few people out there will ever get someone trying to hack in and steal bandwidth.

There is absolutely no need to contact this person.
If your setup is being used, then secure it. Chop them off, simple as that.

Are they connected to your wireless network? If so, the computer name might give you a clue who they are (look in DHCP client list on your router).

The command is

Net Send <computername> Message (Net Help Send at DOS for more info)

But, they may have turned the messenger service off - was a security vuln with messenger.

HTH

Do as Jon suggests.... secure your own network and then forget about them.

Just tried adding the MAC Addresses of the wireless cards into the MAC Filter, but then the whole thing went to pot and i had to reset the router. I do have WPA-PSK security set.

Im still having the same problem, everytime i add the ID's to the MAC filter, the wireless cuts out.

Bear in mind, if you're setting up a laptop, you may well be adding the MAC address of your onboard LAN card rather than the wireless adapter.

Run "ipconfig /all" in a command prompt to see all the available adapters.

I can only see the properties for my card, not the laptops

Obviously if you want to list MAC addresses from a PC you need to run that command on it rather than a remote PC.
