Hi @Mrlard71, you’ll want to login to your Sky router and change it to BRIDGE MODE ... also disable Wi-Fi if possible. Try googling the name of your Sky router and “bridge mode” for directions.

Thank you @press250  but sky being Sky doesn’t allow their routers to switch to bridge mode 

Ooof, @Mrlard71! A quick search tells me that it >is< possible to disable Wi-Fi on your Sky Router … give that a shot as it will ensure that all of your devices only connect to your Amplifi gear.

Thank you unfortunately I need WiFi enabled on the sky router as it creates a mesh to the sky mini boxes around the house ‍‍

I think I will have to take a day out and re configure whole system from scratch 

thank for you help 

FWIW, switching to bridge mode would also have taken out your Sky mini boxes.

It sounds like you have THREE active Wi-Fi networks: Sky, Amplifi, SonosNet. TBH, that is not a formula for success, as the networks are quite likely interfering with each other. I’d suggest avoiding SonosNet because it is most likely the least capable of the three. Try an experiment and remove the Ethernet cable to your Beam and have all of your Sonos devices connect to the Amplifi Wi-Fi.

You really don’t want Sky Q and Sonosnet active on WiFi together. Sky Q and the Sky Q mini *both* use a lower root bridge ID than Sonos for STP (which Sononsnet relies on) and the Sky boxes use the more modern path costs, so it generally doesn’t go well. 

What I’m not sure about is why you have Amplifi *and* Sky doing WiFi? What’s the thinking behind that? 

The trick for this is to have separate SSID’S for the Sky network and the Amplifi. So name one SKY and the other AMPLIFI, (just use your own naming) Don’t worry about splitting bands at this point. 

Let Sky and the extenders do their own thing on its own SSID and then connect everything else to the Amplifi SSID. Obviously connecting the Amplifi router to the Sky Router via a single Ethernet lead.

Keep the beam wired to the Amplifi. On the Amplifi it needs to be in bridge mode, so no NAT or DHCP server running. 
 

NB for anyone wondering you 100% need the Sky router for connecting the SKY TV extenders, its a right pain how it works, otherwise the Sky router could have gone in the bin. Sky do offer (sell) a mesh system to use with their Router which may be something to consider.
 

Thank you,  the reason for Amplifi, is I need it to extend the WiFi signal, Sky just doesn’t cut it to all areas of the house 

And the Sky Q/Sky Mini can’t be ethernet connected to the Sky Router? Are the signals to both from the Sky Router OK? Also, where is the Amplifi unit placed in relation to the Sky Router, which I presume is ethernet connected? 

The sky router is about 2m away from the hardwired beam speaker, and the Amplifi router is 3m away in the opposite direction. Sky router is hard wired into the Ampifi and the beam is hard wired from the amplifi 

it seems if my IP address on my phone which is WiFi linked to the ampifi 168.192.192.110 then Sonos app works, the moment I leave the house and come back and my phone is supplied with a different IP address for the WiFi, I lose the ability to connect to the Sonos app …. 
I have to fiddle around with turning WiFi  on and off until I get 110 address back 

Turn off the DHCP server on the Amplifi, leave it running on the Sky Router. Reboot everything.

Ok, so what IP address range are the Sonos speakers on? Presumably you have the Sky WiFi as a higher priority than the Amplifi? Do you have any devices on the Amplifi where you have setup a fixed IP address not using DHCP? 

And as before, is it impossible to get an ethernet cable to both the main Sky Q box and the Sky Q Mini? 

I have set the all the Sonos speakers with a fixed IP on the AMPLIFI 244, 220, 189, 235, 200,234,233 

main sky q box is hard wired into AMPLIFI Sky q minis are in separate rooms and just can’t get cable to them 

Sorry I have them set up on the AMPLIFI as static leases not fix up addresses 

OK, so just turning off DHCP on your Amplifi and rebooting isn’t going to help you 

The problem I see here is that the Sky Q setup will conflict with your Sonosnet setup on STP. Sky Q uses a lower root bridge ID than Sonos for both the main Sky Q *and* the Sky Mini … The Sky Q STP also uses the more modern path costs so even if you put Sonos in charge, it will make poor decisions… 

I don’t think any of your hardware can compensate for the STP mismatches so the best option I think for you is to not use Sonosnet. That means unplugging the Beam and running all Sonos speakers on the Amplifi WiFi. 

I’m not sure if the Sky Q being plugged into the Amplifi is good or not. I’m guessing you want Sky Q on the same subnet as your phone so something like the Sky Go app can see the main Sky Q box to allow playback of recordings and other control? 

The final bit I don’t yet understand is your phone connectivity. I’m guessing by default your Phone connects to the SKYXXXX network and not whatever your Amplifi SSID is called? (And just to verify, you do have different WiFi names for Sky & Amplifi ?)

Thank you for the info,  phone connects to AMPLIFI. WiFi  and both Sky and AMPLIFI  WiFi’s are named differently 

One of the reasons I moved to SonosNet was that the speakers were disconnecting from the Amplifi WiFi 

since upgrading to the new Sky Router in August, due to the availability of fibre to our house, the Sonos has been unstable and playing up. 

You should be able to create a static lease for your phone, as per the instructions below. This should ensure you always get the right IP for your phone. If it’s an iPhone switch off the Private WiFi Address option as this will stop the lease from working as each time you connect it generates a new MAC address.

Android may have a similar MAC privacy option see here…

For your home network, it’s not always the best idea to keep changing MAC addresses. This may also apply to tablets and PCs/Laptops as well in some cases. 

Also make sure the IP address ranges for Sky and Amplifi are different. 

Longer term, it may be better to collapse down to one address range using the Sky Router, and then run the Amplifi in bridge mode 

https://help.amplifi.com/hc/en-us/articles/220979347-Enabling-Bridge-Mode

If most of your devices are on the amplifi address range, then it may be easier to turn off everything that connects to Amplifi, set the Amplifi to bridge mode and then change the Sky Router network settings to the range that Amplifi use to use. You can then re-setup DCHP reservations… which I believe the Sky router supports. 

That should keep the Amplifi SSID for WiFi, but then you’ll just have the one address range. Keep Sonosnet disabled with Sky Q would be my advice. 

I suspect this is down to the Sky router, Sky Q and Sky Mini’s all acting as a Mesh WiFi by default, and possibly generating interference with the Amplifi signal. So at this point you had 2 competing WiFi networks. When you created Sonosnet you created a third one, but, it’s likely the Sky boxes were controlling the network path configuration (STP) not Sonos (which it needs for Sonosnet to function correctly), so even Sonosnet is unreliable. 

On the 2.4GHz WiFi spectrum there are really only 3 channels, 1, 6 and 11. With 3 networks, unless you had configured them to each of those 3 different channels, they may well have been interfering with each other. If you have neighbours in close proximity and can see their WiFi networks, with 3 of your own, you are only guaranteeing that you will get interference somewhere. 

If the Sky Router is new with the provision of fibre, it might be that you can get away with just the Sky network and lose both the Amplifi and Sonosnet as the Sky boxes will boost the signal around the house. 

Unless Sonos Tech support have some way to allow Sonosnet to interact safely with Sky Q, my experience of the two is that it doesn’t work. I ended up buying a Cisco switch so that I could fix STP properly between the two. However, that’s an extreme solution for most.
