Problems finding Sonos system when using powerlink adaptor to extend home network

It found the router network but could it see Sonos? Why is the signal weak? For this experiment you can stand right next to the router.

And it may be necessary to change that 'n only' protocol to enable b and g. Can't remember if that is needed for controllers, Leave it for now - I don't think it matters when you are in SonosNet mode.

I found this other thread featuring a similar problem with the same router. There is a lot of duff information in some of the posts, but it looks like part of the problem was a bit of security software called 'NetIntelligence" Do you have that?

Hi, thanks. Turned off the TP Link and the Sonos played on, but when I connected to the router network it didn't see the Sonos. Then I had to go out for an hour. When I came back, the Sonos was still playing and the router network was fine to connect phone to Sonos.

I saw that other thread, but I've only ever used the 2.4ghz network, as it is stronger than the 5ghz over distance, and I didn't think Sonos was compatible with it. 5ghz network is only used by my smart TV for Netflix 4k, everything else (phones, tablets, laptops and Sonos is on the 2.4ghz).

I don't have NetIntelligence that I am aware. The issue occurred only from the time I installed the TP Link..

thanks

OK. I never thought it was a 2.4 vs 5 issue - that's what I meant by the duff information, but wondered about the NetIntelligence thing because it seemed to be something that came with the router.

Ideally, since you are using SonosNet, you should have the router, adapter and Sonos on different channels (i.e. one each on 1, 6 and 11. But to be honest this doesn't sound like an interference issue so I wuoldn't hold out much hope there.

It is known that powerline adapters can interfere with the flow of data to controllers, although many people use them without problems. It may just be that. I am sorry we haven't been able to resolve. I think you need to spend some time working with a Sonos technician live, who can remote access your system. We could spend even more time without resolving it.

If all else fails, a dedicated Android device left for control at the router end of the house and connected to SonosNet is a last resort. I use an Amazon Fire tablet as a dedicated controller, and it's amazing value at £50. But you really shouldn't have to go there. Sorry I wasn't able to get further with this, although some useful elimination has been done.

I would expect SonosNet to give you significantly better speed than 0.8mbps so maybe try that again, especially after you have ensured wireless channels aren't clashing.

thanks for your help. I did hear that some people buy dedicated tablets, but to keep one charged etc. it is a bit of a pain. I may investigate getting my SOnos Controller repaired, but as I'm facing into a potential £1000+ investment in new kit I wanted a clear and easy winning solution! thanks again.

THIS ISSUE IS NOW SOLVED:

I changed broadband suppliers (and got a new router - now with Vodafone) and that made no difference whatsoever.

Then John Lewis (UK retailer) recently had a special offer on their Google Wifi 2-pack (saving me £55 on RRP), so I bought it to try, and was going to return it if it didn't fix the sonos issue.

Glad to report, google wifi solved my issue. I have now ditched my TP-Link powerline adaptors (coming to a well-known auction site near you, soon...). For those with a UK Victorian terrace house, the best locations I found were in front reception room and at the doorway to the kitchen.

I now have 38-42mbps in 3/4 of the house and the slowest speed anywhere is 28mbps. Fast enough for my needs.

The system is a joy to set-up and has worked perfectly. I can now control the sonos from anywhere in the house. 🙂

GarryF12 HAS NOT RESOLVED THIS ISSUE.
All he is doing is creating is a WIFI extender like other people have done using a system not dissimilar to Sonos net in operation.
This answer will only work in small properties or ones where the WIFI signal is strong enough to create this kind of subnet. Most tri aerial routers can do this extended WIFI. But when you do this over a longer distance the Download speeds are massively reduced as you have to use your 2 of your three transceivers to make these links.
The underlying issue still exists in that Sonos can not connect to Mains TP-Link type of routers where even a WIFI link is not possible.

And finally Sonos does not work on 5G 2.4 only. however 5G is the best connection and faster than 2.4 in answer to a sub question where this thread has veered off course that has nothing to do with this issue at all.

This is because powerline networking is often too choppy to guarantee the relatively low latencies required for audio data transmission. However, although it's not supported, it does work provided the electrical wiring is up to standard. I've been using powerline extensions with Sonos for years, in two different properties, and it's been working perfectly.

Not necessarily. 5Ghz WiFi has substantially shorter range than 2.4GHz. And, in general, 2.4GHz provides ample bandwidth for audio data.

EoP (Ethernet over Powerline) is my last choice for networking, but sometimes it can be the magic bullet.
