Query: Fatally Flawed

Features & range are good, but the handsets occasionally lose connection with the base unit. Very annoying to miss words during phone conversations. Phone is OK for casual use, but not 100% reliable. AT&T helpdesk blames interference from neighbors' 2.4 GHZ devices. What am I supposed to do? ask my neighbors to shut off their wireless equipment? DON'T BUY.
