Asus RT-N66U guestnetwork not possible

[herby68]

at first hello to everyone here.
I have question to all the experts here, in german forums no one can help me.
I use a fritzbox 7390 as my default router from my ISP . Can not use the asus for this.
The fritzbox is able to have a guestnetwork and it works perfect.
So the kids are not able to connect my other hardware in my network.
Thrue a cable channel I made a cable from the 3 floor ( here is my fritzbox) to the ground of our house ( here is our store ) with a lot of devices that all have to be in the same network.
The Asus is now in the store connectet via Lan cable and I want that our guest can have Internet access without have the permission to reach my other computers and my networkplayer and stuff like this.
But it does not work. Not as router setup and not as AP Point.
When I use the Asus as AP I have not aIcloud option.
the problem all my devices in our store need the same network range to have acces to my satbox upstairs streamming my tv programm.

I am using the latest merlin firmware

any ideas

sorry for my bad english

thx

Two points:

1. What is the reason to not use the ASUS router as the main router ?
2. If it is really impossible, instead of using the ASUS router in the store, why don't you simply use a basic access point there ?

Something to test: connecting the ASUS (in router mode) in the DMZ.

A lot of ISPs seem to be offering up router/modem combos instead of suppling just modems and forcing customers into using their offerings, and in some cases the ability to put these devices in a bridge mode has been stripped or locked away, only accessible by the ISP. I suspect this is why OP can't use his own router.
