My sister came home from college and I am having the hardest time connecting her to the wireless network in my home.  She has a Inspiron 1150 with a 1350 internal wireless card.  The message I get is "The following wireless networks are available.  To access a wireless network, select it from the list, and then click Connect."  Then, "This wireless network is not secure.  Because a network key (WEP) is not used for authentication or for data encryption, data sent over this network might be subject to unauthorized access."  When I click "Allow me to connect to the selected wireless network, even though it is not secure" it says "wireless connection is unavailable"  I also tried to set it up again and just happened to click on ad-hoc network, and it connects and says signal strength is excellent.  I also have my own laptop (Inspirion 1100 with a TrueMobile 1150 card) connected to the network and it is NOT connected through the ad-hoc option.

 

The network set up is a Comcast connection to a Netgear wireless router and is directly connected to a Dimension 2400.  Both the Dimension and the Inspiron 1100 connect to the network and internet with no problem.  I have tried working with Windows to configure the network, along with the Dell Wireless utility.  I have used disks and flash drives to try to set up the network, I have also printed out the settings and tried to manually configure the network.  I have been on numerous websites and changed all internet settings and nothing has worked.  I have even freshly formatted this computer- still no fix.  If you have any suggestions I will be eternally grateful!  Thanks in advance for the help!

 

** Must also add that the Inspirion 1150 works just fine when connected to my TrueMobile 1150 card; however, my Inspirion 1100 will not work with a 1350 card that I have.
