Hi there,

Nobody may help me to solve this issue? 😠

It seems to be very hard...

Next times, before to buy a new technology, I'll wait for reliability.

Sorry to hear about your troubles.  I had high hoped that the B&O wireless gremlins would not infect these new speakers, apparently not.

I have no experience with these speakers, but I've been living with a few Beolink Wireless1s, so here's my advice:

1)  Sometimes moving a device just a little bit (a foot or even a few inches)  one way or another can dramatically improve performance

2)  Can you ever get a "good" status from your wireless TX - that is, if you place all of your speakers within a meter or two with no obstructions, does it show "green" (I assume "green" is good).  I would press my dealer on this point - if you can't get "green" even in ideal conditions, then, to me, this looks like a faulty product - or you have a crazy amount of interference (which is supposed to be unlikely since microwaves, bluetooth, most cordless phones don't use this spectrum).

3)  WISA operates in the 5GHz range - do you have a lot of 5GHz wifi traffic in your home?  There appears to be some overlap of the spectrum.  Try to see if there is some correlation between your speakers turning off and heavy wifi use.  If so, try to increase the distance between your wifi router from your speakers.  Do you have close neighbors who run 5GHz wifi networks that you can "see" in your home?

4)  5 GHz RF doesn't penetrate objects as well as lower frequencies.  I would hope that speaker built for home use could tolerate a sofa in the signal path, but wireless performance can be very unpredictable.

5)  I see some mention on the web of older cordless phones that operated in the 5.8 GHz range, this too overlaps WISA so if you have one of these phones look for some correlation between your speakers turning off and use of this phone.  If so, get a new phone, or, at least, move the base station as far away from your speakers as possible.

6)  Metal is bad for RF signals.  Try to eliminate as much metal in or near the signal path as possible - again, sometimes moving a metal object a few inches can fix the problem.

From the installation guide:

The Wireless Power Link antennas are placed in the lid (top) of the BeoLab Transmitter 1, and due to the PCBs placed below this, the signal strength is somewhat attenuated on the backside of the BeoLab Transmitter 1.  It is recommended to place the BeoLab Transmitter 1, so it is not hidden, and it must never be placed behind the TV as the metal parts will prevent the wireless signals to reach the speakers.

My theory is metal interference from the BV7 stand/TV or wireless interference from multiple 5gHz products in very close proximity. Moving the transmitter answers the first and running a free wireless scanner on your computer will answer the other.  Don't think changing the transmitter should have been the first and second response.  

On your 17's, you should take them to your dealer and have them do a sw update to both of the speakers. I'm willing to bet you are running intro sw. as the symptoms you described were corrected shortly after launch via sw to the 17's only. 

Hi,

I have the same issue with my new AVANT 55 (instead of the BEOTRANSMITTER 1) with my BEOLAB 18 & 19...

It appears that WISA is on the same range of Wifi 5Ghz set top boxes in France and it causes problems : my BEOVISION AVANT 55 is placed just near my "LIVEBOX PLAY" (from ORANGE) : this "box" have 2 wifi signals : 2,4 GHz and 5 GHz but the channel of the 5GHz network can't be changed and it is automatic... So when I turn on the TV, it crashes my wifi network (450 Mbps to 50 Mbps) and the loudspeakers are turning on / off continuously...

By the way, I can't change the position of my box and I can't turn off the wifi 5GHz network (it is "linked" with the 2,4 GHz wifi network).

Do you know if it is possible to fix the WISA channel of the loudspeaker directly ?

Thanks

Fred

Seems that B&O has a challenge in France (and potentially other Geos.) - I urge you to have this reported to B&O (direct and via dealer) so that they give you the best advice and hopefully a fix.

You can't change these manually - it is in the nature of the WiSA technology!

Here an excerpt of the whitepaper:

"When it comes to improving wireless quality, the best defense is a good offense. WiSA audio avoids the popular digital audio frequencies used by WiFi, Bluetooth, baby monitors, and microwave ovens. A set of frequencies have been opened up within the international unlicensed (U-NII) 5 GHz radio band that require Dynamic Frequency Selection (DFS) procedures. These frequencies were historically reserved for weather and military radar applications, but have recently become available as long as conflicts with these important functions are avoided. A WiSA compliant transmitter goes one step further and does its best to find a totally unoccupied channel. Further, it also looks ahead for another unoccupied channel, so in case of interference, it can jump directly to that channel without losing a single bit of audio information."
