The Asus 1000H & WiFi Problems
The ASUS Eee PC 1000H is designed for on-the-go usage, but if the netbook stops detecting or connecting to Wi-Fi networks, it becomes much less useful. If Wi-Fi stops works on the ASUS Eee PC, a hardware malfunction could be at fault -- but issues with wireless connectivity are most often software-related.

Inside the Asus 1000H is an integrated component called the wireless network interface controller. This component enables the netbook to identify and connect to wireless networks in the area. Turning off the WNIC, however, prevents the netbook from finding and interfacing with these hot spots. Pressing "Fn" and "F2" toggles the wireless function on and off. To confirm that the WNIC is turned on, check the wireless indicator light on the front of the 1000H. If the WNIC is active, the light will glow solid green.
BIOS Settings
-
Turning the WNIC on and off in the operating system is much more convenient than turning it on and off in the basic input/output system. The BIOS initializes the WNIC at startup and controls how the device behaves before the computer loads the operating system. It's not possible to make changes to the WNIC settings in the BIOS after the computer has boot to the Windows XP. To check the WNIC settings, press "F2" at startup to boot into the BIOS. Go to "Advanced," then to "Onboard Device Configuration." If "Onboard WLAN" is marked as disabled, highlight the option, then press "+" or "-" to enable the device.

WNIC Configuration
-
Certain WNIC settings can prevent the ASUS 1000H from accessing Wi-Fi hot spots. If the WNIC is not configured to use the transmission control protocol/internet protocol (TCP/IP) or quality of service packet scheduler, problems with wireless connectivity may occur. Changing the network channel to a channel that other wireless devices in the area are using, or setting the network type to "ad-hoc" rather than to infrastructure, can also affect network performance. To check the WNIC settings, go to "Network Connections," which is accessible from the Control Panel. Right-click "Wireless Network Connection," then click "Properties."
Faulty Driver
-
Windows XP, the default operating system on the Asus 1000H, uses special software, called a device driver, to send data to and receive data from the WNIC. If the device driver assigned to the WNIC is corrupt or out-of-date, the computer will stop detecting Wi-Fi hot spots. Upgrading to the most recent wireless driver is recommended -- even if the device is functioning. You can find updates in Windows Updates or on the Asus website. To upgrade the driver, open Device Manager from Control Panel. Expand "Network Adapters," then double-click "Properties." Click "Update Driver" and follow the onscreen directions to upgrade the WNIC driver to the latest version.
