I had the same issue a couple of days ago. I tried a full reset of the puck as described on a sky help page without realising that would take it back to factory settings and needed a complete reset/reregistration. Everything went well until the software absolutely refused to accept the PIN number that I knew was correct.
Got through to a Sky customer service agent in Manchester who was absolutely brilliant. Took me through the whole lengthy process again but at the PIN input screen said to turn the puck off at the plug, wait 3(?) minutes , turn it on again and it will come back on to the PIN screen and accept the PIN.. He did say it might not work😟 and I might need a new puck. Fortunately it did work 😁. Given the doubt you might not want to try this without being on the phone to a customer advisor though!!! So far it seems to have worked.
I really, really, find the constant 'SuperUser' ( are they super users because they spend so much time on the forums or because they know so much about sky technology? I suspect the former) advice - 'oh it's your internet, connect it via Ethernet' to be very frustrating indeed. In some few circumstances where the customer is right on the limit of download speed, 25/30 ish perhaps, this might be good advice. But they offer this advice on every thread, at every reply, without having any knowledge of the customers set up , ISP, router type, download speeds etc. And , dear super users, I don't want to run a Ethernet cable round the house. I don't even want a plug in repeater because I've got concealed wiring, and I shouldn't need an Ethernet cable when a) I'm getting 230 to the puck according to Netflix and b) the system is sold, advertised, and praised for being a WIFI STREAMING SERVICE. Just a thought. 🤔
