I have a Inspiron 5150, a 1350 internal card and a truemobile 2300 wireless router. I also have a Dimension 8100 hooked up thru the router on a cable.  Here is my question.  Why can I connect to my network only when my router is not encrypted.  If I don't secure the network. its work fine.  It tells me my network is not secure but it works.  As soon as I secure the network I lose my connection.  I am not a computer whiz so any help would be appreciated.
