Wireless Networking, a quickie.

Changing your local ip will not strengthen your security per se. Especially if its a wireless setup.
I'm thinking you only want certain PCs and laptops to access your network; And the easiest way of doing that is to permit certain PCs into your network via mac address. How do you access those options depends on your router (brand name and model number would help.) Oh yeah and at least use WEP security.

Jam it back in, in the dark.

Well it seems your router doesn't have that kind of option. Only station MAC filtering which allows you to prevent certain wireless users to not access your router functions =/.

I suppose a alternate way of fixing your security is to turn off your SSID broadcast and change the SSID of your router to something besides "wireless." This will essentially prevent anyone from logging onto your wireless network. Just be sure to configure all your wireless devices/PCs on WEP security before closing the broadcast.

If you need further help on this, just contact me via msn as usual .

There's nowhere I can't reach.
