Listen to this — someone had a BRAND NEW Steam Link that sat on an endless 'connecting...' screen for TEN YEARS. Ten years! No error message, no clue why it wouldn't connect, and the person was just now about to wire £1000 for a whole new Steam Machine because they were so desperate at the end of ten years of failure that another expensive box seemed reasonable. I cannot make this funnier myself — there is something deeply humbling about fighting consumer electronics until you stop and decide 'FINE, I'LL BUY ANOTHER ONE.' And here comes the best part: after a decade of frustration on their Samsung T977C they found it was one toggle. On these TVs even with an Ethernet cable plugged in THE WI-FI OPTION IN SETTINGS STILL HAS TO BE ON for the network stack to route correctly, because remote control functionality depends on Wi-Fi and that dependency bleeds into wired routing too. They flipped Wi-Fi ON, kept the cable in, and it connected instantly after a decade of failure — one setting saved them £1000 and ten years of misery. If you have ever fought a smart device for more than five minutes stop right there and check whether its Wi-Fi radio needs to be on even though you're plugged into Ethernet because the answer may very well be yes, and it could save you a decade of wondering why your new gadget won't connect.
