No, you want to connect direct to the Modem from your new computer. Look for the user's manual online and find out where the Wi-Fi switch is. Sometimes it's a Function key, where you hold down the Fn key and press one of the function keys along the top row. Look for a little "radio antenna" icon on F2, F3 or F4. On other machines it's actually a hardware switch, usually on the left or right sides.

Does it ask for a driver to be installed? Or have you got the wireless version of the mobo that needs an ASUS WiFi-b add-on card with an omni-directional antenna?

Like on the previous version of the mainboard, the PCB contains five PCI slots and an exclusive WiFi slot, in its left part. By the way, when you install the original WLAN card from ASUS into this slot, the last PCI becomes unavailable. Now let’s examine the card, too.

The card supports the wireless networking protocol IEEE 802.11b, describing data-transfer rates up to 11Mb/s. Using the software that accompanies the card, you can use it in the Ad Hoc as well as in the Infrastructure mode, and the card can perform the functions of a programmable access point, providing connections to 31 clients. Thus, the owner of the WiFi-b kit can easily deploy wireless networks and connect to existing ones.

From Asus website:
"The Wi-Fi slot is specifically designed for the ASUS Wireless LAN add-on card"
