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)

Hi ..

Might be corrupted network preferences as a result of the upgrading.

Open the Finder. From the Finder menu bar click Go > Go to Folder

Type or copy paste the following:

/Library/Preferences/SystemConfiguration

Click Go then move all the files in the SystemConfiguration folder to the Trash.

Restart your Mac.

See if that makes a difference.

Your Mac will generate a new SystemConfiguration folder for you.

If that doesn’t help, try here > Wi-Fi: How to troubleshoot Wi-Fi connectivity

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.
