grouping 5hz and 2.4 hz

Hi all

I’ve had the current set for a while now but recently I’ve experienced more connection issues than ever, despite no changes to my set up.  These are especially bad when grouping pairs of speakers with other ones.

I’m on BT smart Hub 2 and I have to use the BT disks to get wifi around the house.

Although I know these are not recommended , as above, it seems to have got worse recently.

I’ve been digging through my wifi app and can see that some of my products connect using the 5hz band and others on the 2.4hz.

Will that make a difference with the grouping and is it possible to make them all use the same?; I’ve read on here that 2.4 is better at reducing interference.

Many thanks in advance

David

On a separate note, I also choose to reserve the Sonos IP addresses in the routers DHCP reservation table.

Presume this is done on the router admin screens?

Yes correct. I’m not sure if this may help you, but it’s a YT video I found in relation to setting static IP addresses for devices on the BT Smart Hub v6. I haven’t watched it, but it maybe similar software to your router and perhaps ‘may’ help you…

cool, thanks - Looking at the screen (too late to attempt it now), it does look like I can configure each Sonos to use static.  I’ll work through each bit in turn, starting with the split SSIDs

Thanks again

    You can't split the bands on the Smart Hub 2.

    Ah - Yes, just seen that!

    So, now what?

    It does look like the IP addresses for the players are set to static

    I do have a play 1 near the router - I have been advised by Sonos in the past to use wifi rather than connect this play 1 to the router

    But then, I’ve also read that connecting to the router will create the Sonos mesh network

    Any ideas if that will be better?

    Try wiring the Play:1. Wait 5-10 mins then look in Settings/System/About My System. All should show WM:0, apart from the Move. If any units (other than the Move) still show WM:1 reboot them by unplugging for 30 secs.

    See how that goes. If there are still problems try different SonosNet channels, then if that doesn’t help post a screenshot of the Network Matrix from http://x.x.x.x:1400/support/review where x.x.x.x is the IP of any player (obtained from About..).

     

    I briefly tried Sonos on the BT Whole Home WiFi and quickly gave up. The discovery packets sent out by the controller were apparently blocked between the bands (and BT WHW can’t split the bands either). The same was true for discovery by the IKEA Home Smart app.

      Is there any MAC Address blacklisting options for the 5Ghz band on the BT router? - I also seems to recall in a previous thread involving that hub, that some users switched off their 5Ghz band, perhaps that’s an option to try (if that feature is available)🤔?

      Personally, I would get rid of it and use a different router/mesh setup.

      It’s a non-representative sample, but the only WiFi I’ve encountered that had per-band access control is ASUS. 

      The 5GHz can be switched off -- mainly to help connect 2.4GHz IoT devices one assumes -- but one clearly wouldn’t want to do so permanently as it would leave only the slow, congested, 2.4GHz band.

      Yeah, I don’t really want to turn 5hz off permanently

      FWIW I have a friend that has this same BT Hub and they have run things slightly better on SonosNet with one device wired to the router, but he still has had the issue of their Move (gen1) not showing up in the App from time to time. 

      He is currently considering either getting his own router, or switching to Virgin Media, but has not made up his mind yet. He did bring the Move around to my Home and I had it on test for a weekend on a Virgin Media Hub v5 to make sure it wasn’t a fault with the speaker and it worked perfectly fine with that router.
