SONY S AIR PROBLEMS

[gritoma]

Hi,

My problem is that my old BDV-IT1000 Home theater which completely satisfied me for so many years start creating  sound S AIR disruptions on the sound reception from my TV SONY 4K ,X1,HDR , X REALITY PRO - KD-55XE9005BAEP.

I follow the steps from the manual in order to pair the S Air  with the unit, it start correctly but aleatory as time duration the sound signal in the two boxes disappears and the red signal of the S AIR device flickering. Some times the sound reappears or it is distorted.

Any ideas about a possible problem of miss-connection/inadequacy due to the 4K TV? If not how ken I solve the problem.

Many thanks for help.

Good advice here, and in the links this article provides:-

https://www.sony.com/electronics/support/articles/00007761

S-AIR works on the same 2.4GHz band that your WiFi also uses (WiFi also uses the 5GHz band as well), and the article(s) linked to explain how you can possibly move S-AIR devices to a different channel within that band (1,6,11) that will alleviate interference between your WiFi and the S-AIR devices.

If this problem has only started with the new TV, then, as a test, turn off WiFi on the TV, and see if the problem goes away.

If so, then your choices are one of:-

(i) use an Ethernet cable, not WiFi, for the TV

(ii) Ensure the WiFi on the TV is using the 5GHz band, not 2.4GHz

(iii) Try whatever adjustments are possible with your devices to be using a different channel within the 2.4GHz band for S-AIR than the one the WiFi is using.

For (iii), to see what channels are in use and which are clear, a free app called WiFi Analyzer from the Google Play Store, run on an Android phone or other device, will show you what’s what with your WiFi. There are no similar iOS apps though, as Apple privacy rules outlaw them, so it must be Android. 

(This app will show you what WiFi is in the air where you are, including your neighbours too, if they are in range, but I don’t know if it will show the S-AIR signal or not).

If you choose (iii) and it works now, but later stops working, in days or weeks, this will be because either your WiFi or your S-AIR has dynamically shifted channels so they are on the same one again, and you will need to repeat step (iii).

Good luck!

Dear royabrown thank-you very much for your advises.

Indeed I changed recently my router with a new generation of TP Link  WiFi 6. That comes with two range of frequency 2.4 and 5 GHz.  On the top of this I also reinforce the WiFi signal on using the second router (same as the other one) using a mesh procedure.  If I correctly understood your technical explanations, every time when the routers are using the 2.4 channel that may causes the interference with my SAir system. OK it could be also different other reasons but my system was perfectly works until the new routers appeared.

What I'm trying to do is to restrict on my iPhone the usage of the 2.4 frequency channel.

If you know a different most efficient method on blocking the 2.4 GHz channel please tell me on a subsequent message.

Again thank you for advises and quick response.

Yes, your efficient mesh system is probably the reason for this. Just as a test, try turning off the secondary router, the one not directly connected to the internet, and see if this improves things.

There are a lot of internet devices that only run on 2.4GHz, so stopping this on both routers would likely make some of your internet devices no longer work, so this would not be a good move.

However, 2.4GHz penetrates much better than 5GHz does, so perhaps you could switch off the 2.4Ghz band on the router nearest the devices using S-AIR, and let the further router handle all the 2.4GHz internet traffic.

How you do this exactly, or even whether you can, depends on the router, make and model, but it’s usually an Advanced setting; have a look in the manual for it, or ask online.

There’s a thing called ‘device steering’, which means that a device that can use 5GHz, and is in range of a router with 5GHz, should use that band, and only use 2.4GHz If that is the only band in range.

But it’s not foolproof, and some routers let you split the bands so you have two SSIDs, one for each band. It is then easy for you to see which band each device is using on the router, and move any that are on the 2.4GHz SSID to the 5GHz SSID, if that is in range and they can use it.

Again, you will need to look in the router manual for whether you can do this, and if so how.

For instance my BT Home Hub 6 will let me turn off either, or both, WiFi bands, but it won’t let me split them, and these things vary from router to router.

Hi royabrown

My professional background is not on electronic field so I try hard to keep the rytm with you.

Everything you posted is helpful for me but, on my side, I never acted as a specialist. Even the mesh system was installed by my internet provider.

What I tried to do with my acceptable skill (as mechanic engineer) was as follow: I have on my Phone two SSID  addresses for WiFi internet one for 2.4 GHz and one for 5 GHz. I put on non-automatic mode the 2.4 one. Also on my TV set I choose only the 5 GHz address.

I do not know if is the correct approach but so far I have a perfect S Air reception. 

I'll keep all of your advises in a file so if sometime the problem re appear I will share them with the specialists.

So thank you so much once again for helping me.

All the best for you, jolly and healthy celebrations for the winter holly Christmas and happy new year.

@gritoma 

Yes, those two changes may well be enough to keep your now-working S-AIR happy.

Another thing I am reminded of from my S-AIR days (yes, I had one too, though I gave it away in 2015) is that, IIRC, you can pair transmitter and receiver devices, which helps them find one another, either when you have more than one set of S-AIR devices or, as here, you are looking for better rejection of other 2.4GHz signals. I don’t know if you have done this or, if not, whether you could try it, to strengthen the bond between them?

But even as things stand, the TV won’t now be putting out 2.4GHz near to the units trying to handle S-AIR, and the iPhone won’t now be trying to find any 2.4GHz on either of the mesh units. (Devices which you wander found the house with can be a bit tricky about hanging on to one mesh device when they should let go and switch to the other one, so you have kept all that kerfuffle out of the 2.4GHz band).

So it only remains for you to mark one of my previous posts as solving your problem, which will signpost this thread and the help in it, for anyone else coming along with S-AIR problems.

Thank you for the Christmas salutations, and consider them reciprocated!

@ royabrown2

So far my system works properly.

Thanks to your advises I can enjoy now my home theater.

At my age I'm not interested to have Hi Fi sound on using the system but being more then satisfied watching movies on streaming channels having surround sound similar to the grand cinemas places and also a better sound reception of my TV set.

Hope also that your answers succeeded to solve similar problems for others users followers of  Sony's forum. 

All the best for you.
