Hi @MrPeebs76
Welcome to the Sonos Community!
I’ve often come across situations where Sky Q boxes negatively affect Sonos systems, but not the other way around.
I recommend you unplug your Sky Q box from power for a minute. If you have a Sky router, the Sky Q box will be repeating the WiFi signal, but if a Sonos speaker connects to it, it can cause problems (for Sonos). Rebooting the Sky Q, if the Sonos speaker is connecting to it, will force the speakers to connect to the router's WiFi. In addition, the issue is more likely to do with the Sky Q box alone, and the reboot may help it.
Failing that, please contact Sky, as I simply don’t see how the reported issue could relate to Sonos (or any other of your WiFi devices, for that matter) in any way.
I hope this helps.
