Sonos Amp and 4 Play 1 Speakers Haven't Worked in 3 Weeks, Techs Can't Resolve

Gold, S2 app. 

The amp is on 2.4ghz

The play ones usually go 5ghz

This is the problem,  when the pay ones get on 2.4ghz they play, this is the core problem,  amp doesn't go into 5g network. 

2 speakers are playing now because they found 2.4ghz.

Which model Router or Gateway are you using?

CGM4331COM

I really don't know if that's it from the picture, meaning from all these numbers which one is the model when it didn't say model on it. 

This model is also known as “XB7” and “TG4482A”. Are you using any of the Xfinity pods? I’ve had a couple of very poor experiences with the Xfinity version, yet I’m using another version of  that hardware daily with no SONOS issues.

It’s not very easy to navigate their support site. I’ll post this link because it might lead to something useful for someone who has more free time to dig further.

I have a wifi extender pod, I disabled it for a while and nothing changed or mattered as the speakers are still jumping into the 5g band. The Sonos network is clearly doing this and the heart of my issue…

Amp 2.4ghz

Play 1 speakers 5ghz

I need for the speakers to jump into the 2.4ghz band. 

How do I do that aside from doing a wired setup?

While my phone is also jumping on 5ghz I suspect that never mattered since there weren't any issues with that part for years. 

Thanks

I have a solution for now..

A friend had me go into my Xfinity router online

I turned off the 5g network (not real pumped about that)

You can't split bands on the white Comcast pods

Sonos Play 1 speakers then found the 2.4ghz network after I did a diagnostic check to find them. 

I like the idea of 2 networks and have the Sonos on the 2 4ghz but that's currently not possible and I'll need an exigent router that can support 1000mb speeds too. 

 But…

The Play 1 speakers NEVER went to 5g before the update I did like 3 weeks ago. I had 5g and this specific white pod router for over a year without issue, something in the updates must've changed but if so, will it get corrected and we will all find out so guys like me can go back to 5g at my home?

Xfinity buys those pods from a 3rd party. The Xfinity configuration, in my opinion, is junk. I’m using the same pods (with a general purpose configuration) for my SONOS system without issues.

If you need additional access points I recommend dumping the Xfinity pods and use something else.

I have a SONOS system (Wired and Wireless) connected to a Xfinity XB7 Modem through multiple TP-LINK Managed Ethernet Switches. All SONOS wired ports are connected to the Ethernet Switches which have RSTP configured properly. My wireless SONOS devices are using SONOSNET. Use the Help About on the SONOS app and confirm that you are connecting the XFINITY Wi-Fi which I think you have already confirmed. All of my wireless SONOS are showing VM:0 which indicates SONOSNet.

We started having some music drops and SONOS wireless zones disappearing, and this started to occur after the SONOS V14.20 update. During that same time, I think XFINITY pushed an updated to the modem as it reset a couple of time one night.

I also have the 2nd generation Xfinity Pods to extend the Wi-Fi network, but these are not being used by my SONOS equipment.

 

Update for Friday Dec 30th, long one and I'm done unless something else stupid happens to waste my life. 

The Sonos system eventually went back onto the different networks, unreal. That's partially due to Comcast I think but who cares, it never happened before the update from like a week before this thread. 

After hours going to Comcast and other days talking with techs they did nothing but make things worse. Actually days ago it was so bad after 80 minutes I had them put me back to normal and we're done. 

Now, I was told my router was a GP7 or whatever it's letters are,  the 1st tech said that's a new merged router that chooses the band for the items, or whatever. Can't be split but…

GP6 can be split into separate bands that you can send items to. Ok cool, they're gonna send me that one. 4 days later,  I get the exact same router I have GP7. WTF

BTW, I now have to go there and return it, wasting more f'ing time so I'm gonna waste their time and talk with the manager about this bs and get a credit. 

So I decide to wire 1 speaker to ethernet (Sonosnet?) and the system finds the 2.4ghz but it's choppy with drop outs every 10 seconds. This happens for over a week and really sucks for music classes. 

I just did the latest Sonos update, now it works like before, solid and no drop outs. WTH??

All this started with an update I didn't need to do, all this bs ended with an update. I could've saved at least 10 hours of my life and $50 minimum on a Netgear router so.....

Moral of the story, don't update if it's working correctly. I'm not updating the Sonos app anymore. 

Sonos should consider releasing updates linked to software techs pay, you miss something you miss money. Us costumers have this very thing happen to us but worse, we lose time chasing ghosts that can't be resolved easily or at all by us. 

After a month of zilcho my $1700 system finally works like it's supposed to, but after all this I'm looking for your replacement as my music classes weren't so great during all this down time. I wouldn't have needed to do any searching for your replacement if the techs can test the updates on a smaller scale first and get feedback before going full scale. Or at least put out a comment to all customers through the app that you're working on the resolution so don't chase any ghosts wasting your time on something you the user can't resolve.
