Hi  damocles, Welcome to the Community, If you're looking for an option to delete the preferred list of networks on Dell TrueMobile WLAN Card Utility,you can refer to this link below : support.dell.com/.../utility.htm Look for section which says "To view or modify the wireless network properties (Windows XP environment) Hope this helps, Thank You
I recently bought a Netgear Wireless Network Extender, which I was unable to install correctly.  After a lengthy call to Netgear support, they advised me that the installation had failed because I had supplied the wrong network key. It seems that before I try again I have to delete the networks that I created with  "-ext" prefixes from a list of preferred networks.  Netgear could n't help me with this becuse thay have no knowledge of the Dell Truemobile utility. Can anyone advise me what to do? 
How do I delete "preferred networks" using the DELL TRUEMOBILE utility?
