BASIC Wireless Troubleshooting Steps:
Verify that the network adapter is being seen by the operating system:
Check Microsoft Windows Device Manager and look for an icon that appears as Network Adapters and see if the network card listed in Mini-PCI information table is installed:
Verify that the radio is enabled:
It is possible to disable the transmitter of the wireless card without Device Manager showing any problems. Most wireless cards will put an icon in the system tray (the line of icons in the lower right corner of your screen). Right click this icon and it may have a menu option to enable/turn on the wireless radio.
Check for association to an Access Point:
If you double-click the previously mentioned system tray icon, the configuration utility of the wireless card will appear. This utility will be able to show the status of the wireless card, showing what channel the card is using and what signal strength is being received. It may be difficult to maintain a connection if signal strength is low due to either interference or distance. For example, interference can be caused by 2.4GHz cordless phones, other Access Points in the area, and physical structures such as load bearing walls or metal partitions.
Note: The utility can be used to configure the wireless card settings, but if using Windows XP Zero Configuration or Access Connections, you will need to use those programs to actually configure the wireless card as they will overwrite the setting of the utility.
Check the SSID (the Network name of the wireless network you are trying to connect to) and security settings:
Note: The SSID and WEP key are case sensitive.
Note: It may also be necessary to temporarily disable the security features in order to check for basic connectivity.
Verify that the most recent driver for the adapter is installed.
Verify the hardware compatibility with the Access Point:
Often, vendors of Access Points will add features to improve their product. Unfortunately, these extra features are not always compatible with all hardware. Consult the product documentation for the Access Point about the possible need to disable these features. Also, there are often new firmware updates to an Access Point that may solve some issues. Again, consult with the Access Point manufacturer for updates.
Verify that TCP/IP (or other appropriate protocol) is properly installed:
To check this:
Note: Only use a Static IP Address if your network/Service Provider requires one.
Verify the TCP/IP address:
Ping the loopback address:

Install latest Service Packs for Operating System or Network Client:
It may be necessary to install Service Packs for either the operating system or for any additional network clients that may be installed. Contact the software vendor for these updates which are usually free downloads.
