So, after a terrible thunderstorm my built-in network adapter died. Since I had an Apple USB Ethernet adapter (which I used with my MacBook Air), I've just plugged it back and got internet running again. BUUUUTTT, App Store wasn't working anymore. I've read a lot of solutions online, tried most of them and the only one that was truly useful is the one proposed by RehabMan (thank you so much, mate).
