If your device cannot see any wireless networks that it can connect to, use the following troubleshooting steps as a guide to finding the solution:
1) Some models have a Wireless switch located on the device itself. Be sure that the switch is in the "On" position (Note: Some units use a keyboard shortcut to enable/disable the wireless feature. With this method, press and hold the Fn key, then press the F2 key. There should be a pop-up window in the lower right hand corner of the screen indicating that the wireless has been enabled or disabled.)
2) Check device drivers to be sure the wireless device is updated. To do this; Click on the START button, right-click COMPUTER, click MANAGE. In the left pane of the new window, click DEVICE MANAGER. If there are any network devices marked with a Red or Yellow icon, install or update the driver(s) for that device. You can find drivers for CTL computers here: ftp://ftp.ctlcorp.com/PUBLIC/NOTEBOOKS/
3) Be sure that the wireless source (Router, Access Point, Wi-Fi, etc.) is actually broadcasting wireless signal. If other wireless devices are able to detect the signal, this is a good indication that the source is broadcasting. If there are other devices with the same issue, or other devices are not available, simply powercycle the wireless source. This is done by unplugging the power cable to the network device, waiting 30 seconds, and plugging it back in. This will refresh the device and ensure wireless signal is broadcasting.
