Question about Computers & Internet
There is no sure way to stop intruders - if they want to get in they can and will.
However in saying that you can certainly be smarter than the average jo driving around an estate looking for open wireless routers.
First thing first, always change the default password for the router (admin, password). If you can, change the username also (from admin to something else).
Secondly I would recommend that you enable some kind of WPA (or WEP) protection. This basically means that anyone attempting to connect to your wireless will require a "password" to connect to you. The more bits the password has the longer the password is and usally the harder it is to crack (via a brute force attack).
Thirdly - Hide your SSID. All routers by default show to the world they exist. If someone doesnt see it broadcasting generally they wont know its there.
Forthly. I would recommend setting up access lists. On every network card (be it wired or wireless) has a unique identifier called a MAC address. An access list restricts which MAC addresses can physically connect to your router. To find out your mac address click Start - Run. Type CMD. Type IPCONFIG /ALL
Fifthly - This may require a bit more fiddling around between both the router and PC's but may be worth it in the long run. Most routers broadcast whats called DHCP. This is what gives you an internal IP address. If your router allows you setup the DHCP settings to something incorrect EG: Different Subnet mask, DNS settings, Default Gateway. Then setup your home PC's manually to the correct settings. This way if someone does end up cracking your router it will throw another curveball at them as they will not be able to surf the net, view your shared files, without more fiddling.
As far as PC based security goes, I would suggest that you check any shared files or folders you may have and disable, setup how many people can use it at once, permissions etc for them. Best way to check would be Click Start - Run. Type \\127.1.1.0 <- This will connect to your pc via the network.
