Sonos Sub too far from AMP

  • April 5, 2020

I am wanting to set a sonos sub up in a room where i have ceiling speaker connected to a sonos Amp.

The Amp is in a closet where I have a “home run” setup.  It seems the Sub is too far from the AMP to get a signal from it in the room, I can move it to a different room, closer to the Amp and it will work.

 

Evidently the sub talks directly to whatever its paired to and not separately like other sonos speakers.

 

Is there any way to get a better signal to the Sub?  current setup is WM:1

 

thx

    Hello @Mayo,

    Welcome to the Sonos Community and thank you for reaching out with your set-up question.

    Since the Sub communicates to its parent Sonos player via 5ghz, if the Sub is out of range of your Amp you will not be able to bond the two reliably if at all. 

    There are three options available to you from what I can understand of your set-up:

    1. You can opt to bond your Sonos Sub to a different product that is within 10-15 feet of the Sub. 
    2. Relocate the Amp physically within 5g range of of the Sub and the ceiling speakers.
    3. Try wring the Sub to your network (I personally don’t like to recommend this) as this will put the Sub directly in network communication with your Amp.

    I’d be interested to hear about which option works best for you and you can certainly submit a diagnostic report from your system if you have any difficulty. Include the confirmation number in your response and we will be happy to look this over for you.

    Looks like it’s having issues today.  Sonos app says the sub is “not configured”.  Unplugged it and it was able to connect for a short time then disconnected again.  It may be just be I cannot place it where it is...

    Actually…..appears my 15 year old unplugged the Amp from the router, so up and running again….

    So final outcome is it does have issues when grouping several amps together for music, I assume this is the latency spikes ratty was mentioning.  I have decided to go back to having the system use my WIFI instead of the sonosnet, I can tell the app itself is overall more responsive this way.

    Maybe sonos will have an update that allows the sub to resort to 2.4ghz if it can't get a good 5ghz signal.

    Again, appreciate all the help here.

    thanks

    would a Sonos boost help my situation(the latency spike issue)  if i were able to wire it into my Satellite Orbi(which is hard wired to router), there would then be about 10’ of distance b/t the boost and the sub?

    Ratty - it is possible for me to add 2 Sonos boost, one at each orbi router(which are hardwired together). I could then plug in an amp to the boost and piggy back the other 3 into each other and disable their radios.   The 2nd boost, as I mentioned above, would be about 10’ from the sub.

    would this be a good solution?  And would this be less susceptible to the latency spikes?

    It might help to install a wired Boost or two. But at the moment we’re rather driving blind.

    Go to Settings/System/About My System and note the IP address (x.x.x.x) of one of your players, then point a browser to http://x.x.x.x:1400/support/review (substituting the above IP). Click on Network Matrix, screenshot it and post the image. 

    To recap: This method of connecting the Sub is decidedly not a supported option, but it may work under decent conditions. If your problems occur only when players are grouped there may be a better order in which to group them, so as to reduce overall 2.4GHz bandwidth demand.

    Ratty - I set my sonos system up again in SonosNet mode and it just doesn’t play nicely w/ my orbi mesh system, it causes my phone to constantly lose wifi.  I also couldn’t get the sub to connect via 2.4ghz this go around, nor could i figure out how to screen shot the network matrix - it was larger than the screen, i assume i have too many sonos products to get it to fit.

    Until sonos comes out w/ another option to pair the sub w/ a product(Amp) in my case when its further than same room I will just not be able to have a sub.

    thanks again for the help

    I’m having the same trouble, I hooked up 6 AMPs in my rack hard wired to the network switch, the I try to sync a Sonos sub in my dining room about 100ft away and the sub won’t work, the I add a Sonos boost hard wired to the network which is like 10 ft from the sub and the problem stills.

    i also have a sonos beam wired to the LAN paired to one amp (surround) and a sub (wireless) and it works fine.

    Should I deseable the wifi of the Amp in cuestión, and. Should I keep the boost? 
     

    i have good wifi signal with hard wire access points. 
    Al the players are in the same floor, just the sub and the boost ate down stairs. 
     

    thanks.

    Using a Boost is often a generally good thing, but it doesn’t address the fundamental issue, which is that the Amp is trying to communicate directly to the Sub using their 5GHz radios, and not using your WiFi for this data traffic.

    ‘Disable WiFi’ on the Amp actually turns off itswireless radio so if you turned that off you would have to wire the Amp, Sub and surrounds.  If you did that (if it is practical) then you might get the whole thing working.  I wouldn’t guarantee it though.

    This was an incredibly helpful thread.  Yes, the Sonos private 5g wifi range between the sub and the amp has limits.  Had exact same issue: amp that drives my inhouse ceiling speakers is in a basement closet, and desired sub placement is in kitchen diagonally opposite upstairs.  Sub would connect if placed in a room almost above the basement closet, but not much further away than that. 

    Fortunately, I had an unused cat5 internet jack in the kitchen.  Added a wired access point to that jack (which greatly improved kitchen wifi), but it still did not allow the Sub to connect to the downstairs amp in either amp-wired or amp-wireless mode.  The solution was to add a Sonos Boost, which is plugged into the kitchen access point. All set.  

    Definitely some improvements needed in the set up instructions to help people with this fairly common scenario -- lots of ceiling speakers out there.  And, adding a sub where needed really adds tons of quality to those ceiling speakers!
