Hi Baby Boomer,

iMac 21.5 inch, late 2013
OSX yosemite 10.10.4
My other products, iPhone, iPad, apple watch, and apple TV all connect to the internet without any problem. I have deleted the cashe, reloaded the OS, and still when I wake up my iMac, i must restart to access the internet.

Is this a wireless connection? If so, do you have the same problem if the iMac is connected through the ethernet?
Repair permissions and restart your comp. If that does not help, try the following:
Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
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. Report back the results.

I'm having the same issue with my MacBook Air 2013. Wifi is completely grey'd out, cannot even turn on/off. Roommate's Windows laptop works just fine.
Restarting brings it back for a bit, but after it fails to connect it goes back to grey.
