Thanks,
I'll bear that in mind when I upgrade my machine. I suspected what you
say was true!

Hi Bill,
Yes, when you do an upgrade In-Place preference files are sometimes
not updated, (hence your really out of date prefs files). Some can be
corrupted causing issues in the new upgraded OS.
I would say you haven't done a Clean Install for quite a number of
years! 2001 wow ;-)
A Clean Install of a new version of OS X is a good idea, it clears out
all the old 'junk' of years of previous OS updates and Transfer &
Setup migration to newer Macs.
A clean install does involve more work but you know you won't have any
problems after a clean install.
Cheers,
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!
