Can someone please give me a step by step guide on how i can secure my network to only allow certain computers (by name if possible). I have just noticed that someone has had access to my network without me knowing and i would like to stop this from happening again.

I am using...

The router
Linksys WRT54G

Cards in 2 pc's
Linksys WMP54G

and a 10/100 linksys card in my main pc.


I am a newb to network security and need the guide please. :(
 
Thanks for the link oddjob62 i will take a look.

@Zildjian

All this encryption stuff is so confusing to me.Can you explain how to use MAC filtering? Could you also tell me if
change the default SSID or even stop broadcasting your SSID

can be done easily and as i forgot to mention in my first post i have a LINKSYS WGA54G WIRELESS 54G GAME ADAPTER which would need to be set up.
 
Thanks for all the info guys it is much appreciated.Although i would like to follow the direction of using WPA,i have just realised that i can't as the WGA54G GAME ADAPTER mentioned earlier can only support WEP (I think),I have set that up and also changed the default password for my router. Is there anything else i can do?
 
Thanks for the tip Charlie i will take a look and check it out (never thought of that). I didn't want to use WEP but i were limited with the gaming adapter:)
 
Well that's that idea gone there is no firmware update for WPA and doesn't look like there will be as i think they are fading this model out now.
