The wifi of my muse luxe is very bad. Is it possible to improve it, for example with an antenna? I have the version with the IPEX connector. Can I connect a 6db antenna like this one?

Yes you can try but the hole that you will need to do will void your warranty
Ok, but as it is now, it’s not usable to stream music.
hi, could you elaborate a bit more, how are you streaming your music? thx
I’m streaming with HA: media_player.play_media and use an URL as the source. But either the connection is lost or the ESP reboots. The external antenna did not help.
are you using the last version on apps.raspiaudio.com ?
last HA version?
Yes, current version from that page.
as we have changed the yaml recently let me try, do you stream with the media player or music assistant?
I stream with HA: media_player.play_media
