Thansk Ronni.

I deleted the files you specified. The com.apple.airport.preferences.plist was dated 2008! All working again.

So I'll watch and wait. I noticed quite a few plist files with dates going back to 2001.

Thanks.

Hi Bill,

What have you tried to rectify the Wi-Fi issue?

I have not experienced any Wi-Fi issues after upgrading to Yosemite. I’ve had a few clients that did experience Wi-Fi issues after doing an In-Place Upgrade (not a Clean Installation). I was able to fix their Wi-Fi problems with some fairly simple troubleshooting.

Manually trashing the Network plist files should be your first line of troubleshooting. This is one of those tricks that consistently resolves even the most stubborn wireless problems on Macs of nearly any OS X version. This is particularly effective for Macs who updated to Yosemite that may have a corrupt or dysfunctional preference file mucking things up.

*Remove Network Configuration & Preference Files*

*1. *Turn Off Wi-Fi from the Wireless menu item

*2.* From the OS X Finder, hit Command+Shift+G and enter the following path:
*/Library/Preferences/SystemConfiguration/*
*
*
*3.* Within this folder locate and select the following files:
*com.apple.airport.preferences.plist *
*com.apple.network.identification.plist com.apple.wifi.message-tracer.plist
 NetworkInterfaces.plist
 preferences.plist*

*4.* Move all of these files into a folder on your Desktop called ‘wifi backups’ or something similar – we’re backing these up just in case you break something but if you regularly backup your Mac you can just delete the files instead since you could restore from Time Machine if need be.

*5.* Reboot the Mac

*6. *Turn ON WI-Fi from the wireless network menu again

This forces OS X to recreate all network configuration files. This alone may resolve your problems, but if you’re continuing to have trouble there are other steps you can do to resolve wireless problems.

Post back with details what you have tried before I suggest any other steps to take.

Cheers,
Ronni

Wamugers,

Yosemite 10.10.1  had the habit of closing down WiFi after "sleep".

10.10.2 was said to fix that. For me it has not. It doesn't happen as often but still there!
