I’m having a weird issues with my Sonos setup.
Let me first give some information about my setup.
I have a dozen Sonos devices (Play:1, One, One SL and Roam). All these devices are connected through WiFi to my Wireless network (UDM-Pro with UAP’s). So I do not use SonosNet, nor wired Sonos devices.
I have a separate IoT subnet for my Sonos devices, and my controllers are on another subnet. My UAP SSID’s are also split up into different WiFi networks.
Although my Sonos devices are on another network, for now I have allowed them through the firewall with restrictions only based on their static IP (no port restrictions). I have also enabled mDNS, IGMP snooping, Multicast enhancement.
My controllers are installed on 4 devices: Windows PC, Surface Pro 2017, Samsung Android phone, Huawei Android phone.
Below is a per controller device issue description:
1. Windows PC (Wired) - No issue, connects and works, sometimes with limited delay.
2. Surface Pro 2017 (Wired) - No issue, connects and works, sometimes with limited delay.
3. Samsung Android phone (WiFi):
- 5GHz band on the controller network turned off, so phone connects to 2.4Ghz: It works.
- 5GHz band on the controller network turned on, so phone connects to 5Ghz: It doesn’t work (Sonos system not found)
4. Surface Pro 2017 (WiFi) - Does not work, neither on 2.4GHz as 5GHz network (Sonos system not found)
5. Huawei Android phone (WiFi) - Works on both 2.4GHz and 5GHz band
The Sonos devices are a connected to the IoT SSID on the 2.4GHz or 5GHz band depending on Sonos device.
Has anyone encountered this somewhat strange (to me) issue?
It seems to me that this is any issue on the controller device side and not on the network side. I can live with using only the 2.4GHz band on my controller network. The biggest issue for me is that the SP2017 cannot connect through WiFi, because when I work on that (undocked) I do not want to go to my phone everytime to change/add songs/volume.
Thanks in advance.
