After updating to OSX 10.9.4, WiFi connection keeps getting dropped. This happened on 3 Macs, but my iPhone, iPad, and Windows computer all connect to WiFi just fine.
I recently updated three Macs to Mavericks OS 10.9.4. All three Macs now cannot stay connected to WiFi.
Other devices (iOS and Windows) have no such problem, so it isn't the WiFi itself.
It seems to be OS X 10.9.4 which is the problem.
10.9.3 did not have this problem either.
Mac mini (Mid 2010), OS X Mavericks (10.9.4), Also MacBook Pro and MacBook Air
