G3-100 Router Set Up and Activated OK but no Wi-Fi!!!! yet Ethernet ports work fine.

Ok, I'll just state that I'm a retired electrical engineer who's worked in networking for decades so if I'm stumped God help the rest of us.

Went through the G3100 install although it's a bit silly to suggest looking up the instructions online when there's no way to go online without the router working!

So I followed the directions on the box.  I used the EXISTING cabling that my old router was using. I did NOT install the coax spliiter (more later). The G3100 is connected to my ONT via both ethernet and coax, which is how my old router was set up. I have an Apple Time Machine box which has it's own wi-fi network connected to the G3100 by Ethernet. 

I first tried to connect via W-Fi using my MacBook Pro. I set up the name and password in the Mac's Network preferences and it complained that "there is no IP, cannot connect the the internet". Cool  🙄  Did the same with my MacBook Air, same result. No sense trying the iMac...

So how am I able to type this? Because the wi-fi network of the Time Machine not only works, but it is connecting to the Internet over the Ethernet connection to the G3100 😡 

What about the coax splitter? It does NOT match the splitter already in place. In particular the label shows a different range of frequencies (the new extends to 1675MHz, the old spliiter only to 1000MHz). Better yet the new splitter has one in but only two outs marked -3.5dB. The old splitter (added when I had my ONT upgraded a few months ago (I'll skip THAT horror story) has FOUR outputs and they are marked (+)7.5dB.  I can't imagine why the old splitter would interfere with the Wi-Fi but as with all things Fios, anything is possible.

I've put my request for a call from support in, but while I'm waiting maybe some of you have run into this idiotic problem and know how to fix it.

Well, it turns out that the activation screen telling me everything was OK and go start browsing the web neglected to mention SOMETHING REALLY IMPORTANT.

Um, REBOOT THE ROUTER.

I am typing this right now connected over Wi-Fi to the G3-100.
