Sadly I'm back a few days later to report that the 'fix' is only temporary.  This issue continues intermittently.  The above suggestions solve the problem for one or two restarts, then I'm once again 'Not connected to the internet' and must do all that all over again.  I guess these are the famous Yosemite wifi problems. Ironic that I don't use wifi but have Time Machine installed and so I have the problems anyway.

 

Any who finds a permanent fix, please let me know.

    OSX Yosemite Wifi issues

     

     

    Are you connected to internet through ethernet?  If so, run the diagnostic test if you have not already done so.  Post the results.

    Not a wifi issue.  I'm on cable.  Have to unplug modem and replug it in, then I'm 'connected.'  Every time, so far.

    I don't know how to do that.  What I'm directed to do here is turn off my modem, turn it back on and if everything works, I'm fine. And I am. But later when I turn of my computer, and turn it back, I get a 'not connected to internet' notice when I start up Safari and Mail just posts little !s  because . . . I'm not connected to the internet.

    Disconnect & reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.

    System Preferences>Network

    Click the Assist Me button.

    In the next window that pops up, click the Diagnostic button & do the necessary.

     

    http://support.apple.com/kb/HT1714 Solutions for connecting to the Internet, setting up a small network, and troubleshooting

     

    What to do when you can't connect to the Internet

     

    =================

     

    If none of the above suggestions work, do the following as a last resort:

    1 - Repair permissins & restart your computer. 


    2 - Run OS Recovery

    Disconnect all devices from your computer except for the keyboard & mouse.

    Boot up from your computer by holding down the command+r keys.  This will take you to the recovery drive.

    Select Disk Utility & hit Return. 

    In Disk Utility select the HD on the left & click on Repair Disk (bottom right).

    When you reach the desktop after doing the above, repair permissions & restart your computer.


    3 -

    Trash the following plist files by going to Macintosh HD>Library>Preferences>SystemConfiguration

    com.apple.airport.preferences

    preferences

    NetworkInterfaces

    Repair permissions and restart your computer.    If the problem has been resolved, empty the trash.  If not, you can return the plist files if you wish.  New plist files will be recreated anyways.

    Thank you, Baby Boomer.  I'd begun using Airport Time Machine (for its backup capabilities only) for the first time prior to upgrading to Yosemite.  With the upgraded OS my system needed to reconfigure my network from ethernet access to Wifi (even though I don't use wifi to access my internet . . . it's now 'there') and was a switch that had to happen manually in the Preferences pane you suggested accessing. 

     

    Now working at startup, so thank you for your excellent input.
