If I stand right next to my network extender, it works great. the moment I move outside a 15 ft ring, I begin to drop calls. i believe it is because my Blackberry is now getting a stronger signal from the outdoor network and I should be handing off to outdoor network. Instead of the call continuing, it drops. Also, the same thing happens when I am on a call inside my house, get into my car and drive away; I drop the call. I have called VZW Tech support and was told to power down the unit, yadda, yadda, yadda and call back if I still have the problem. Well, I still have the problem, so I am posting this in the hope someone has seen this and it saves me the hour long support call that doesn't resolve my issue...
