Generally I do

Lately I notice the Beolab 19 shows the red light and then the green light and that's happened a few times since a firmware update.

I wasn't sure if it was the firmware update or wisa. If it continues I'll disconnect and reconnect the sub in speaker groups and see if that works

The bl19 is wisa with an avant.

Same here. I have a pair BL17

One speaker is 10cm away from transmitter and the other 200cm, both have their occasional drop outs.

Apparantly the signal gets disrupted easily depending on where the transmitter box placed.

Would I have known, I would not have choosen the wireless route. I also tend to believe that sound will be better with cables - but that might be wishfull thinking 😁

Ok. I have BL18s and one of them occasionally (once a week) goes silent, red light goes on then immediately green. Then the sound always restarts. Takes about five seconds in all. It's just one speaker (I've swapped them around). I've managed to replicate this by moving the transmitter box through 90 degrees which caused it to occur. So it is definitely a WISA issue in my view. The transmitter is within a couple of metres of the speaker.

I've reported it to my dealer who in turn has reported to B&O. I'll post any progress.

Have any others manufactures made products with WISA?

I've got no inclination to move to 'wireless' speakers in the future.  The reason?  They aren't wireless - not until you can send electricity via the airwaves (much like Tesla claimed he could do! ) There will always be a power cable so why not just use Powerlink cables and put them, with the power cable in the smallest cable tidy/sock available?  It looks neat, and the permanent cables don't produce drop-outs etc.

The acronym for WISA does not hold up at all if people are having these sorts of problems with it.  Hardly 'Immaculate Sound' if none is produced.  It's beyond me.

I have two Beolab 18 and One Beolab 19 too. How Do you Do a Firmware update?

I've posted before about this issue. I always thought that the obvious thing to do was to send the speaker signal via the mains. Maybe there are technical reasons why a clean enough signal cannot be sent this way, but so many things are now done via the mains right down to plug-in baby listening devices.

You go the B&O site and use this page:

I use this method for Wi-Fi around the house.  It's OK but in some houses (like ours) there are multiple circuits i.e. between floors and even different rooms or between sockets within rooms and the signal does not cross between two different circuits.  It won't operate via a trailing socket (technical reasons) and signal strength is lost over distance.

Would be ideal though.
