If you're familiar with wireless networks, the information in the "Summary" section is probably sufficient; if not, go to the Table of Contents below and find the section that matches your device's operating system.If you're having trouble connecting to a wifi network, you can sometimes fix the problem by removing and re-adding that profile.

Windows XP does not have a built-in way to scrub saved WPA credentials - see How to remove cached user credentials that are used for PEAP authentication in Windows XP.

As of December 2013, the QOOQ tablet does not support WPA2-Enterprise.

Please refer to the documentation of your vendor's card in order to turn it off as this may interfere with the procedure here documented.

The SSID can be customized not only to make it easy for you to identify the name of your network but for security reasons as well.

One way to restore networking, especially wireless, is to go into control panel, system and delete the network card.

Since you mentioned that this notebook had previously been setup for multiple wireless profiles, my suggestion would be to delete all existing wireless profiles and see if that allows you to then create a new profile for the Comcast gateway.I can't provide a screen shot to illustrate how to do that because I don't know if you are using the built-in Windows Wireless Zero Config, or a vendor specific utility for your unnamed Wi Fi card.Make sure that the WLAN light is on or flashing, check the settings whether the SSID is broadcasted.There are unverified reports that it is possible to jailbreak older Kindles and create scripts to manually join WPA-Enterprise networks ; try at your own risk.For newer versions, follow the directions for Android, above.Given that the underlying OS is Linux, it might be possible to root the tablet and manually connect using wpa_supplicant etc.; given the risks (including bricking the device), we can not recommend the attempt.
