wifi with Yosemite
Since upgrading to Yosemite often the WiFi connection drops and I need to restart the Mac Book Air to get it back
MacBook Air, Mac OS X (10.7.5)
That makes a lot of sense. I have a home configuration using Airport, and have no problems with my new MBP 13 Retina. But at our lake house with the cable company-provided router, I have constant dropping of the wifi. I created new locations and reentered the DNS, and it works for a while then stops working. I am not at the lake anymore, but if the problem is there again next Spring I will be back at this thread.
