Hi!

I recently bought a pair of BeoLab 18 speakers. After one month with the BeoLab 18, sometimes the speakers won't connect, red light. Sometimes only one of the speakers are connected. I find the WISA connection a little bit unstable.

BeoLab 18

Sony TV

Transmitter 1 (Airport Express RCA, Sony TV TOSLINK)

I wonder if people find WISA stable?

Hi all, just registered here and thought it was about time to start share stuff and participate in the discussions on this great forum.

I can more or less confirm that the connectivity issues that is reported in this thread are all due to disturbances from wi-fi router communication. Probably from the 5ghz band which is quite close to the bandwidth that WISA is using. I experienced the same with my setup and the solution is very simple. Configure your router (both 2.4ghz and 5ghz) to a fixed channel instead of using the default that is "automatic" I for instance choose channel 11 for 2.4ghz and 44 for 5ghz. I experienced A LOT of drop-outs when I installed my setup and I also initially blaimed the WISA. But since the above change/config was mad I haven't experienced one single drop-out and have been running flawless the last couple of months.

The main problem was i my living room where I have the following setup:

- Beovision 11
- 4 x Beolab 18
- Beolab 19

All connected through WISA via the built in module in the BV 11

So all of you that encounter problems - try the above and I would bet it fixes the problem. Try different channels also and focus on the 5ghz band. Could be worth mentioning that I'm running Time Capsule and Airport Extreem that extends my wifi. But should be the same for all routers

Cheers,
Lukas

I tried with fixed channels, but the problem is still there. I haven't tried with all the different channels, but I have decided to use cables. The Bang & Olufsen Store suggested using the BeoPlay S8 Connection Hub. It fits my needs, and it will most likely not cause any connection trouble.

In other words, WISA is not stable in my opinion. Hopefully this will change in the future.

JoostdenEngelsman:

My dealer blames the 5ghz band on my router (Apple Extreme) which cannot be switched off, causing interference with the WiSA connection. Does anyone have a solution for this (other than switching to wires)?

I have experimented the AE in the same area as my Moment, BL 18 & 19 ..... not good at all, event after testing several channel combinations. I move ithe AE  to another area of my house and installed a Linksys WAP300N as it only services 2.4Ghz.

BS Moment, BS Core, BS Ouverture, BG 4002, BS1, BL18, BL19, BL8000 + RCV1, A6, M5, M3, A1, P6 (tks Botty), H5, TR1

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 Big Smile

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.

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.

I'd forgotten that many ISP's actually prefer router extenders to work via the mains, so the technology is there. There's a good chance that in any one room in a UK house that the sockets are on the same ring main. Having said that I do realise that the use of ring mains rather than radial circuits is probably unique to the UK. It apparently arose from the post WW2 shortage of copper.

So maybe the use of the mains was dismissed due to radial circuits not necessarily being linked to each other. But it would certainly work in the UK for individual rooms.

You will have to admit, that there always already are several power outlets in a room, so getting power to a BL was/is (mostly) never a problem.

But in a lot of cases getting the soundsignal to the speakers would be the problem - for lots of different reasons.

I regard the WiSA connection as an option for these cases.

And I think, that it is fine, that B&O can provide 'the best of all' wireless connections - the WiSA-one.

However, if you can hardwire an audio connection, why shouldn't you do so!

There is a tv - and there is a BV.

Thank you for bringing back memories from the first half of the Sixties ... every time we moved to a new house (OK, twice) my father would pull up the floor boards and skirting boards to lay in a ring main (or maybe he was talking it out) and I would be crawling around, torch in hand, lighting his way ...

I'm sorry to hear of several folks' WISA issues, I hope they get resolved. But I'm of one of the camps in this thread. I'm likely going to get a pair of WISA speakers in the very near future, but even with that capability I'm going to hard wire them to whatever system they'll be connected to, for me, at least, there's always some peace of mind that when it is connected, it'll just work. But having the option to test placement without worrying about that extra cable is great. That is, test placement first using WISA, then then you've found their place, hard wire them.

Hi, I hope you will get this sorted.  I have transmitter1 and beolab 17.  It has been rock solid.  I did notice that the transmitter light was bleenking some days ago like it was receiving an update.
