To set-up and secure the wireless router from unauthorized access, follow these steps: -
1. Connect the wireless router to your computer with a LAN cable.
2. Start your browser and enter the router's configuration URL IP address.

5. Go to the wireless settings and change the default SSID and turn off SSID broadcast.
6. Setup encryption key the strongest is WPA2 (if not then WPA).
7. For further security measures - turn on MAC address filtering and enter the MAC address of the wireless cards on the computer/s you want to connect to this wireless router.
8. Record the settings you have made and keep it in a safe place and Save the settings.
9. Configure the wireless cards on the computer/s with the SSID and encryption settings of the router.
10. Remove the LAN cable between the router and the computer then the computers should be able to connect to the router wirelessly.

Lost internet connection morning of 1/15/08 through router and directly through laptop 1. But, can get internet connection directly for laptop 2 and laptop 3! Cannot get a valid IP address anymore when laptop 1 is directly connected. Also, I discovered ping works for any lettered website even when the router is not connected to the wall, but correctly times out for a numbered website (eg 216.31.156.10). Completely stumped. Please help!

Do you need to see the desktop or just share folders from each other? If the latter then you need to do the following:
Use Windows Explorer and select a folder you want to share. Right click and select sharing and security.
On the sharing tab click on Share this folder. Enter a share name ( I like to enter the PC name _folder name; Rick1_Downloads)
Click on Permissions. If your ok with everyone using the PC's and Laptops having access then highlight Everyone and click on Full Control.
Do this on each PC and Laptop.
That should be it or darned near close.
