Software Troubleshooting

Because you've already checked to confirm that your hardware is using the correct drivers, what kind of software-related problems are left to check? Two things come immediately to mind: the wireless adapter configuration utility and the WAP's firmware version.

As mentioned earlier, some wireless devices won't work correctly unless you install the vendor-provided drivers and configuration utility before plugging in the device. This is particularly true of wireless USB devices. If you didn't do this, go into Device Manager and uninstall the device, then start again from scratch.

Some WAP manufacturers (I won't name names here, but they're popular) are notorious for shipping devices without the latest firmware installed. This problem often manifests as a device that enables clients to connect, but only at such slow speeds that the devices experience frequent timeout errors. The fix for this is to update the access point's firmware. Go to the manufacturer's Web site and follow the support links until you find the latest version. You'll need your device's exact model and serial number- this is important, because installing the wrong firmware version on your device is a guaranteed way of rendering it unusable!

Again, follow the manufacturer's instructions for updating the firmware to the letter. Typically, you need to download a small executable updating program along with a data file containing the firmware software. The process takes only minutes, and you'll be amazed at the results.
