Hardware :: How To Piggyback A Airport Extreme Off Of Verizon Fios Router?

I am looking for an individual who can spend some time to carefully take me through the steps of piggybacking my Apple router off of my new Verizon router (pictured above).

I realize some of the process is discussed earlier in this thread but I found some of it difficult to follow, and I think I may have a newer Verizon router than what may have been previously discussed.

There are also some functions of this Verizon router that I cannot have disabled.

Will talk about all of that below...

To Begin With

I switched from DirecTV to Verizon Fios this past week.

The tech who came to my home told me that I would need one of their routers if I wanted the DATA (channel
text information) transmitted to all the displays in my home.

This would mean, of course, my Airport Extreme Router would have to go.

Since switching to the Verizon MI424WR router, my Wifi signal at far ends of the
house constantly goes up and down. This was never a problem with the Apple router.

Need to Piggyback the Apple Router but not disable critical Verizon Functions

I need my Apple Airport Extreme router back.

Problem is, the Verizon router provides critical data information to all my displays. So,
hopefully there is a method that I can piggyback the Apple Router and turn off the Verizon
WiFi function without affecting its data transmission to the other televisions.
