Hi all. Hope everyone is swell.
I have a few SONOS 1s, a Beam, and one of those IKEA speakers all happily working together.
Over the summer I updated my wireless router from an old single band one to one of these new fangled (for me) routers with the multiple bands. I bought the seemingly popular TP-Link AC4000 Smart WiFi Router (Archer A20).
Here’s the situation.
My iPad and laptop both have never had issues with connecting to the SONOS system. They work great.
My iphone, on the other hand, constantly loses it.
All apps and OS are up to date. It’s not a distance from the router issue as they’ve all been tested mere feet from the router. I was just browsing SONOS on my iPad and had phone next to it and the phone can’t find the SONOS devices.
This may be more of a question for the TP-LINK folks, but I wanted to try here first just in case. You’ll see in the screenshots that my phone is on it’s own 5Ghz channel. I suspect that is the issue but not sure why or how the router’s ‘smart connect’ single SSID/band direction would throw the phone to it’s own separate band. Very odd.
