The electricity was turned off today for 20 minutes when it came back on the box that runs the tel and Wifi keeps beeping. Tried alsorts switching it off on again etc. it needs someone to come out and sort it as it is very annoying

Could you post a photo of which box you mean? Sky hubs have no speaker built in to make a noise and I dont think Openreach ONT's can either
