Summary: When waking up my Macbook after suspended activity, the WiFi connection takes from 10 to 30 seconds to be active again. Steps to Reproduce: 1. Connect to a WPA-protected wifi network. 2. Close the lid of the Macbook, and wait for the computer to go into suspended activity (a dozen of seconds, I guess) 3. Open the lid. The screens turn on, and the Desktop appears (there is no lock screen on this session) 4. Try to display a webpage in a browser. Expected Results: The webpage should appear quickly (in 3-5 seconds after the computer wakes up). Actual Results: The webpage appears after 10 to 30 seconds. It seems that the WiFi take much longer to reconnect than before. Regression: This used to be very fast on the same Macbook on Mavericks. The upgrade to Yosemite made it slow?
