Hi @WowAndFlutter
To me, right now, it looks like your Move is online.
Given that, and what you have reported, it looks like the Move is staying connected (though my checking once is hardly proof) but communications are being blocked. This could be due to your router(s) not passing certain types of network packets from WiFi to LAN (SonosNet results in the router thinking all SonosNet-connected devices are on LAN), or something else. The Move not giving you a weather report refutes this, however. More information is needed, and the Move has it.
A factory reset is the last thing I’d recommend. Literally. At this point, I don’t think you should even reboot your Move as that clears the internal logs. Please get in touch with our technical support team.
If you really want to try something without first getting in touch with our technical support team, you could try assigning static IP addresses for your Sonos devices, especially the Move, in the router’s settings. Reboot everything that relates, or connects to, the network afterwards - and I do mean everything. Get your network up and running before turning on/reconnecting client devices such as phones, computers and Sonos devices.
I just realised that location and interference haven’t yet been mentioned - I presume you have tried moving the Move, and it behaves the same in all locations? If not, that would be the first thing to try.
