Calls drop on WLAN UMA home net -8120 Pearl

Since I have had this phone 4/08, maintaining UMA connections has been poor.  Calls often switch from UMA to TMO mobile net during calls.  I think it happens when not on calls too, but I'm not looking at phone when not in use.

I've verified phone is set up to optimal with TMO support, checked WLAN AP/router too, followed BB Tech Sol. Center recommendations for supporting voice on WLAN APs.


Seems to me that received signal on Pearl is weak even when within 10 ft of AP (-40DBi).  When moving around my little house, signal is usually down around 70-80DBi.


What else am I missing?

Is the Pearl antenna inherently weak?

Is there a way to boost antenna power on the phone?
