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.

The Moment Installation Guide has some tips about how to place 5GHz devices, I've copied some of the recommendation below in case you don't have the guide in hands:

Distance between 5 GHz transmitters

The number of 5 GHz transmitter systems in the near surroundings has impact on the stability as each transmitter occupies bandwidth and therefore in dense signal areas infuence each other. To obtain the most stable wireless transmission, Bang & Olufsen has made a number of recommendations for the setup of transmitter systems.

A Bang & Olufsen stereo system setup or surround sound system setup is regarded as one transmission system and consists of a WPL transmitter and all WPL associated speakers. Similarly a 5 GHz Access Point and all associated computers is regarded a transmission system.

  • -  The distance between a 5 GHz transmitter and a speaker must be no more than 12 m / 40 ft; see page 18.

    -  The stereo/surround sound setup must be within an area of maximum 9 × 9 m / 30 × 30 ft; see page 18.
  • -  Transmitters and speakers must not be placed closer to other wireless units than 1 m / 3.3 ft.

  • -  There must be no more than three transmission systems within an area called the 6 m / 20 ft zone, see illustration A. *

Power-up sequence

- In case of more Bang & Olufsen WPL systems in the same room, it is recommended to power only one at the time and wait at least 1 minute before powering up additional units.

* In countries with less than 6 channels available, see page 61, it is recommended to have only 1 additional transmitter system within the 6 m

Site survey (Wi-Spy)

Setting up Wi-Spy

Usually wireless speaker connections should not lead to problems. The WPL Tx module is able to nd unused channels in the 5 GHz band, and makes a map of unused channels in case the present channel in use becomes occupied by another transmission system. In such case moving to an alternative channel happens seamlessly.
Despite this it is recommended to make a site survey in dense residential areas as well as enterprise areas, in countries with few channels (see
page 61), in areas known for wireless problems and if many 5 GHz transmission systems nearby.
In a repair situation a site survey can also reveal if problems are related to lack of channels in the 5 GHz transmission system.
The Wi-Spy DBx + Chanalyzer Pro can be used to visualize which 5 GHz channels are used and unused.

Note: The free-ware program inSIDDer can show all channels, and identify WLAN traf c, whereas it is not able to see radio traf c from other transmission systems using the 5 GHz band (see page 61).

I went from the Transmitter 1 to wired. My dealer didn't have another solution unfortunately. I have a AirPort Time Capsule, and neighbours with Wi-Fi. I find it a little bit misleading, when they say in their commercial that they have found a robust and high quality wireless connection.

Aussie Michael:
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.

So i disconnected the speaker connection on the avant and reconnected it - haven't had an issue since

It's a wireless product so i think they do get confused.

Hello, I had the same problem, but the dealer updated the software on transmitter and loudspeakers. After this everything was solved.

Just for curiosity, who of you use Wisa and have more or less 0 dropouts?

An update on my earlier post.  I had an occasional drop out on one BL18 speaker. I swapped my speakers around and still got drop outs in the same location (different speaker). So there is clearly a problem with the location itself relative to the transmitter. 

Thanks to the ever helpful Nick @Sheffield who provided me with a 5 metre cable (BM5 to transmitter 1) I have tried a few different positions for the transmitter and now seem to have no drop outs. The transmitter used to be at floor level but raising it at least 12 inches from the floor has made all the difference.

Hi,

I've had the same problem. The solution in my case turned out to be: placing the Essence hideaway box on the floor and putting the Transmitter 1 ON TOP of it. (Initially the hideaway box was on top of the transmiter)

It's good you have a solution. I have read that the two boxes (essence and transmitter 1) are best at least 12 inches apart so that they don't interfere with each other. If yours are working fine then that's great. But if you do have any further issues it might be worth separating them.

2 years Essence and BL 18 and 1 year Avant. No drop outs but occasionally the WiSA doesn't find/connect to the BL18 which is 4m away from the Avant. Dealer blames 5g network on Apple Extreme but it is far away and I have manually moved the 5g network to a band range which is far from the WiSA range. No real solution other than disconnecting power on BL18 and reconnecting. Most times WiSA then connects. No interim drop outs.

Six months now with 4xBL18 and a BL19 connected wirelessly to a BV11.

Things were terrible when my router was running both 2.4 and 5Ghz networks. The router is near the TV and I currently don't have an alternative location for it. So I had to disable the 5Ghz network, after trying every channel, even the ones which are more distant from the Wisa frequency.

Since I disabled the 5Ghz, I never experienced a single problem with any speaker.

Thanks Marcello. Unfortunately, Apple Extreme routers do not allow for disabling the 5ghz frequency...

I had forgotten about it sorry. I was under the impression that you could disable by Alt-Clicking Radio mode in the Wireless Options window of Airport Utility but I was wrong, I double-checked and you can only have better control on the protocols.

BTW, if you need a suggestion for an alternative I switched to a Netgear R6250 as the access point in the living room and to a R7000 as my main router. The extreme (the "brick" version) became too obsolete for my needs.

Edit: By the way I can confirm that when I had the 5Ghz I had no dropouts. Either the TV would detect the speakers at power-on or it wouldn't.

I have a Beosystem 4 with a Transmitter 1 and 5 Beolab Receiver 1s. I've owned the system for 1.5 yrs. I have had numerous random dropouts (Speakers power off out then back on moments later). The situation appeared to be associated with heat. See http://forum.beoworld.org/forums/p/18059/157824.aspx#157824 where another user and myself have attempted to rectify the problem. After placing feet on the Transmitter 1 and installing  two 120mm quiet fans behind the Transmitter 1 I haven't experienced any subsequent dropouts. I don't have 5GHz wifi in my home, only 2.4.
