Poor WiFi and bluetooth connectivity
WiFi and bluetooth connectiviity on my Muses suddenly started working only on small distance (Bluetooth connection to earbuds may fail even at distances <1m.) I installed apps for measuring WiFi and Bluetooth signal strength on Muses, and they show much lower values than I get when measuring by phone at nearly the same location. Measuring Bluetooth signal my computer gets from Muses shows reasonable values, so it must be a problem of receiver. Also, I think (not sure) Bluetooth problem started a couple of weeks later then the one with WiFi. My old LB Plus also has poor WiFi connectivity.
Has anybody else experienced such problems. Should I try to open Muses and clean it? |

These are interiors of my old Plus. (I cannot charge it anymore due to faulty USB port). I wonder if the gray wire at the left side that got detached from the board may have served as WiFi and Bluetooth antenna.

A WiFi aerial is about 1cm to 4 cm long folded metal or shaped PC tracks fed by a thin coaxial cable (an outer screen and concentric inner wire). That grey wire only for WiFi if it has an inner and outer pair of wires. I can't tell from the photos.
Cleaning would have no effect. If the aerial has come out of place or one wire is damged? |

Update: the grey cable does seem to be coaxial one. Last edited by ilyats; 03-12-2021 at 11:23 PM. Reason: More info added |

So the small PCB is an aerial and the grey wire is miniature coax cable, like on a TV set or satellite box, but much smaller!
The location of the PCB aerial can be important and they can come loose. |

[Solved]
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.
