However, I was continuously plagued with mysterious dropped connections during the "connecting to " phase. No rhyme or reason, resetting, turning wi-fi on or off, location or distance made it better. Then one day, I tried syncing a second time, and it worked! What was the trick? I have the "auto keylock" preference turned on. After I realized the only difference was that the keypad was opened during the successful sync, I now manually lock the keys and leave the keypad open during a sync and have 100% reproducibility of "good" syncs! Hope this helps someone as much as others' hints have helped me!
