Everything was fine in 10.1.x, when I went to 10.2 I started having problems connecting (dial up) after waking from sleep. I posted here a couple times and tried everything I read here and elsewhere....nothing correctd the problem. FINALLY....10.2.3 came out and as usual I upgraded right away and it's fixed! My QS 933 connects everytime like it used to. Thanks Apple for finally fixing my problem.
