Re: WiFi interface disappeared
Dan Thanks for replying. As I mentioned the WiFi on the same box runs fine from Ubuntu or from Windows.

Yes, r8169 is a realtek driver, but it's for ethernet devices not wifi. I'd expect to see an rtl81xx (maybe rtl8192) or similar module. Next step is: dmesg | grep rtl and lets see what we get.

Re: WiFi interface disappeared
Aha! Moments before your message arrived, I did uname -a. It showed 3.17.4-301. I was scratching my head trying to figure that out. Looking at your message, I checked the /boot/config, and it correctly shows 4.1.6-100. I started poring over /var/log/messages, and I see that when the problem started, my BOOT_IMAGE changed to /boot/vmlinuz-rescue-0... What I *hadn't mentioned* (because I didn't think it could be relevant) was that I had also done an upgrade of all of the Ubuntu packages. As part of that process, Ubuntu took over grub. Since I still saw Fedora on the grub boot menu, I thought all was fine. Little did I know that the evil Ubuntu had changed the Fedora entry to it's rescue image! Now I just have to figure out how to get grub back to where it should be, and I think everything will fall back into place! Thanks for the help guys, this one was a tough nut for me.
