"This is an old unit" but I bought it 2 years ago......My gut feeling is there was a firmware update on your WIFI unit and because it's ONLY 2 years old, the thing broke! Am I right? This unnerves me too! I remember the day when appliances would work 10-15 years. Now, if I get 5 years out a fridge, I am happy. This is the decline of Western Civ.
