erm... OK.
I'm using a NETGEAR modem/router (all-in-one gizmo).
I set it up using my laptop (we don't have desktop in the flat) and it all works so I unplugged the Ethernet cable and now we are all able to get on the net using the lappers.
I assume that I am the admin for the network? How does one go about getting into the router? And my wireless network card is a built-in one if that makes any difference...
Right it's probably easier for you to just set up the encryption.
In order to get into the router you need to find the router's address and type this into the address bar in your browser. Usually it's 192.168.1.1 but it could be something different.
As for the admin, you'll need a password to change settings. Usually the password and user names are just admin/admin.
Usually the instructions help as well
