    Just curious at how any wireless router could be able to set such an option.

    Is it possible to set my WRT54G's wireless network invisible to any other people and just assign my notebook/network cards mac address to match what it has on the router and "to see" the network?

    Many thanks to anyone who replies,

    On most APs/WLAN Routers you can disable SSID broadcast. This will at least hide your network from people without much wlan knowlegde.

    But if someone has a little bit experince with wireless netowkring and the right software, he can still detect your wlan. Well, actually he only needs to know how to use Google, as there are plenty of tutorials describing how to detect networks with hidden SSIDs.

    It's the same with MAC address restrictions. This will stop people wihtout computer/networking knowlede to access your WLAN. But MAC addresses can easily be changed. So anybody could change the MAC of his WLAN adapter to match the MAC of one of your netwokr cards and the AP will not be able to tell, if it's really you loggin on, or if it's someone with a spoofed MAC. Also lots of tutorials out there, describing how to do this.

    The only real protection for your WLAN is a good encryption (at least WPA). Of course, if your WLAN is properly encrypted, there is no anymore need to hide it.

    Actually disabling your SSID broadcast makes it harder to establish connection, using WPA-PSK. If you use someform of encryption, most people will leave your network alone. If security is an issue, use WPA or better WPA2.
