Sonos not working - error 1002 when playing spotify, error 1101 when updating

Sonos uses SSDP multicast/broadcast for discovery of devices across the entire network subnet. So it’s not like other network devices, which often just have a single connection to the internet.. the devices need to communicate with each other across your wired/wireless access points - so it’s best, particularly when grouping the speakers,  to have your WiFi access points operating on the same fixed WiFi channels and not changing channels automatically. Usually non-overlapping channels are used, which are either channel 1, 6 or 11.

In your case, I would personally try wiring one Sonos device only to your main router, set the router and Time capsule to both use, say ‘fixed’ WiFi channel 6 (with a channel-width of 20MHz only for the 2.4Ghz band) and then set the SonosNet channel in the Sonos App to either 1, or 11 and see if that improves things.

If (and only if) you don’t have any Sonos portable devices, you can also remove the WiFi credentials in your Sonos App network settings - if you do have portable devices, then leave the credentials in place.

I would only wire the one Sonos product only preferably a modern standalone device and keep that a metre away from the router aswell - do not wire anything to the other access point(s). If problems continue after that, then I would suggest coming back here and I can maybe suggest an alternative setup to try, but this suggestion should hopefully work well for you.

• set both router and Time Capsule 2.4Ghz WiFi channel to channel 6 (automatic channel selection disabled). Try again with both Sonos speakers still connected through WiFi; still 1002 error when playing music, and 1101 error when trying to update.
• router and Time Capsule still set to channel six, connect one of the two Sonos speakers through Ethernet cable, set Sonos net channel to channel 1; still 1002 error when playing music, and 1101 error when trying to update.
• remove ethernet cable from Sonos speaker, and set all WiFi broadcast settings back to auto. Disable Sonos setting “set time from internet”, and manually set date to 16 december (ridiculous I know, but I am getting desperate here); still 1002 error when playing music, and 1101 error when trying to update.
• Try to enable Sonos setting “set time from internet” again, but the setting switches back to being disabled, probably due to the same external internet connection issue.

What happens if you just use your Fritzbox router only with the Time Capsule powered off? Does it work then?

Just to add, I’m just wondering if you did setup the Time Capsule in ‘bridge mode’, or if you’ve left the router/dhcp functions active? Although earlier you did say you had it as a network access point using the same SSID etc? Make sure it is bridged off your existing Fritzbox subnet.. there’s a couple of links below, if you perhaps need any assistance with that:

• https://www.macobserver.com/tmo/answers/how-to-add-a-time-capsule-or-airport-extreme-to-an-existing-network-with-br

During troubleshooting 7 days ago I already confirmed that whether the Time Capsule is turned On or Off I still get these same 1002 / 1101 errors.

Nevertheless the Time Capsule Wi-Fi mode is set to “Create a wireless network”, and it creates a network with the same SSID and password as the network my model/router creates.

The Time Capsule setting advanced / DHCP and NAT the Router Mode setting is set to “Off (Bridge Mode)”. 

Well the setup all sounds okay to me in that case and obviously you’re internet connection is working, so not sure why things aren’t working as they should be, unless there’s a fault somewhere, or the network isn’t configured correctly? I’m really surprised it doesn’t work when in wired SonosNet mode, assuming all are on the same subnet? Especially as the guest networks were switched off earlier. It’s like some kind of isolation/connection-blocking issue.

Anyhow, maybe the next best step is to speak with Sonos Support Staff via this link below and see if they can maybe see what the issue is through your diagnostic report:

I just connected a switch to my router through an ethernet cable and connected both Sonos speakers to the switch each through their own ethernet cable.

• in this setup I still get the 1002 / 1101 errors when trying to play music or update my system.
• I then removed the stereo pair to go back to the most simple situation having two separate speakers. I still get the 1002 / 1101 errors.
• The separate systems show up ik the Sonos app with WM: 0.
• I noticed that in the Sonos app both systems still have Wi-Fi enabled, even though both now have an ethernet cable plugged in.
• When I try to disable WiFi for each speaker I get an error message saying: “Wi-Fi not disabled, make sure this product is connected to your router with an ethernet cable.”
• I verified the switch has a functioning connection to the router by plugging in another device in one of the other ports and streaming a video with WiFi on that device turned off.

Alright, if there is nothing else to try then let’s see if I can get a response or support from Sonos staff.

Thanks for the helps and suggestions in any case.

I assume the mobile controller device is connected to the Fritzbox router main WiFi and it’s connection is not isolated in some way?

Is there any firewall, or other security software on that controller device that might be blocking things? Is it an iPhone/iPad? …if it is, try switching off ‘private address’ (MAC spoofing) in its network connection properties.

I suspect the Pi-hole. Internet access from the Sonos is evidently failing. Take the Pi-hole entirely out of the equation and see if Sonos behaves.
