I cannot connect my Soundtouch 20 to my new WiFi network.

Silent Starter

I cannot connect my Soundtouch 20 to my new WiFi network.

I have just moved to Sky Q and as a result have a new router and wifi network to which I now cannot connect my Bose Soundtouch 20.
The Soundtouch is a couple of years old and had no issues connecting to the previous wifi network but it is not picking up any connection.
Has anyone experienced similar issues and are you able to suggest how to resolve this please?
Thanks, Matt
