Hi @MichaelWeis 

Thanks for your post!

I agree - that is weird, to say the least! There shouldn’t be any way that contacting your email service on your PC (or anywhere else) would disconnect your One SL from the network.

I recommend you reboot your router by switching it off for at least 30 seconds while no-one else is using the internet. It will take a few minutes for WiFi to return. My initial thought is that if activity elsewhere caused a disconnection, it seems most likely to be the router at fault - assuming this issue is repeatable and the timing wasn’t just a one-off coincidence, that is.

If it ever happens again, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports - but please do so before making any attempts to recover the speaker’s connection.

I hope this helps.

I’ve rebooted my router.  Let’s see if it drops again.

Indeed: Hard to imagine a causal connection between opening an email and the SL dropping from wifi.  Possibly a coincidence, although there wasn’t any delay between the email window opening and the SL dropping out.
