It might help if we knew the make and model of your Bluetooth Speaker. It's pretty unknown from what I can see. After I bought it, it was hard to find. Yafeite brand, model #: K7
One other thought, when the Bluetooth drops out, by any chance are you using a microwave oven in the other room? Microwave ovens use the same 2.4GHz band that Bluetooth and WiFi are on and often created havoc with early Bluetooth devices.
