Yes. I upgraded yesterday and ever since them I have dropping connections. All other devices on the network are fine so must be my computer (air) at issue. Have tried various fixes posted on apple support communities but nothing is working. Very very annoying
Updated, and so far no issues to report for me either. Have a MacMini 2011, and the full reformat/reinstall (no upgrade) of 10.8.4, and it went smoothly with the WiF.
