Some people have the connection problem - I did, but haven't had it in two weeks or more. Don't know why. BTW I refer to the wifi, but the same fix works for 3G, so I think your N9 suffers the same bug. I don't know what triggers it, but it's not a problem for all people, just some. You got unlucky. I would still like to know if my fix works for you, btw. I have cut up 3 SIM cards (instructions from google) to microsim, all work fine, and all work ok in a self made converted back to miniSIM (= standard/regular SIM) format. (Full size SIM is credit card, the card one usually has to break the SIM out of before sticking it in a phone.)
