Airport Extreme connected via wifi to that network
The Ethernet ports are not enabled when you configure the AirPort Extreme as you have done with a third party router.
Unfortunately, the AirPort Extreme will not be able to do what you are trying to accomplish using wireless.
Ironically, the less expensive AirPort Express will likely do what you want.....but make sure that you understand the store's return policy before you buy, if you want to give an AirPort Express a try.
Otherwise, connect the AirPort Extreme to the FIOS router using a wired Ethernet connection.
Thanks for the info Bob. I went ahead and purchased a used D-Link Bridge from Amazon Warehouse Deals for 30 bucks. It's gigabit and will give be 4 options, 3 of which will be used from the get go. Thanks for the quick response. I'll be selling my AE on ebay for a quick turnaround. Too bad that device is so limited.
I would try to set up a MoCA network through you Cable TV Coax lines. It is faster than wifi
If you add an additional Tivo and want to strem between them, you will not be able to do it over wifi.
If you have a cable line that leads to your router/cable modem and one that leads to your Tivo/TV than all the lines are in place.
The latest Tivo Boxes have MoCA built in.
If you want more than intenet access to your Tivo. You could split the cable line at the tivo and place a MoCA network adapter at that end and give a wired network connection to any device at that end.
MoCA is the way to go.
I had not considered MoCA before. Sounds like a great option, however, after briefly checking prices for an adapter it appears to be well over twice as expensive as the bridge option I've chosen. Although, I probably could come close to breaking even when I sell my AE. I don't plan on being in this house for much longer than a few more years so I'll probably hold off on that until I later.
Thanks for the reply though, that's a great option I hadn't heard of from anybody!
