I opened my Muses and figure out that the thing I was pointing with finger at the photo was the aerial. (If you try it, be sure not to lose the power button, it is tiny and falls out. Needless to say, If you try it I am not responsible for any damage you may cause.) The soldering of between it and the connecting wire had been broken. A kindly guy soldered it back for me and now the connectivity is normal. That guy soldered the aerial of my old LB Plus as well, but he was unable to fix its USB port, so I cannot test it.
