Got a network extender,(Samsung SCS-26UC4) hooked it up to my broadband... everything works great now. Previously nothing worked. I thought it was strictly for phone call enhancement but all my apps fire right up and run without stutter. I even try to run 4 or 5 apps simulatanously in hopes of finding the limitations. It all runs well now... from not at all. My home signal was -95 to -120. now it's -80 to -95. Big difference and helps all operations across the board. I could not be happier. Surprised VZ nav is having troubles because one main issiue for the extender is to get satelight positioning first before operation. But my Magellan would run circles around the VZ nav unit. Maybe you just cant find satelite positioning from your location... I've heard of this. Are your regular apps running right?
