Your description must be the issue with my BT headset (the LG HBS750). When connected and utilizing both the audio and media profiles and listening to music (fm radio/mp3s), the headset disconnects and the wifi disconnects. But not at the same time. I go through trying to pair the headset and phone again and again (and the wifi too). It takes about five attempts until everything gets connected but after another 10-15 minutes, the problem repeats. After trying many work-arounds, I discovered that enabling only one of profiles at a time keeps a stable connection. Since I only want to use the headset to listen to fm radio and mp3s, I selected the media profile to be on. Now the BT and wifi stay connected without any drops.
