Securing a wireless connection

To add to previous comments, when connected to the router (hardwired connection), go to your start menu, run, and the type in 'cmd' (no quotes). This will open a command window. In the window type 'ipconfig'. This will give you your ip address, as well as the gateway. The gateway is the address of the router. By typing this address into your browser, you should be able to access the router configuration menus (might have password if you had previously set 1, or the default (you can check with the manuf website to learn the default). Then it's just a matter of setting either your wep key, or setting wpa or any other means of security you want to implement.

I all else fails ... CONSULT THE MANUAL !! . I you have lost it, just chech-out the D-LINK website & forum.

To secure your wireless connection, do you mean by
1. Encryption using WEP or WAP
2. MAC address filtering on your wireless card
3. Disabling SSID broadcast.
If so you need to configure your wireless settings using Internet Explorer, the URL would be http://192.168.2.1 (check the config. TCP/IP address in your manual)
