I currently have an Inspiron 8250 configured with a True Mobile running wireless internet through a Lynksys router.  The range is limited to the first 2 floors of my home.  I was advised that if I hook up a WAP11 to a CAT5 entry point on an upper floor, the lap top will respond to this signal for internet access when out of range of the Lynksys on the lower floor.  Is this correct?  I am most concerned that the True Mobile can respond to each router.  Thank you.
