@Freestone81 I'm sorry to see you're having problems with your smart hub 2 and wifi discs, I've started your own thread as the one you posted on sounded more like a network issue where yours is likely a wireless problem.
When the connection drops in the evening is it at the same time everyday?
@Freestone81 no worries, it'll probably be easier to manage your issue on a separate thread. Is there anything electrical being used or switched on in your home during the evening when this happens that's not on during the day?
@Freestone81 As a start it would be good to rule those out first as they may be causing interference on the wifi signal causing the drop out. Post back and let us know how you get on.
@Freestone81 how did you get on with your checks?
