Unable to connect to sky hub

[Rossiii]

My sky hub has worked fine whilst I've had it for the past year, however this morning no devices were able to connect except when connected by an Ethernet cable. Have tried everything but can't get it to connect

@Rossiii Have you just tried switching the hub off for an hour then back on to see what happens!

Someone did post earlier today that all there android mobile devices failed to connect after something happened overnight,

so not sure if hubs have been FW updated or something else went on with sky server's.
