Everything on NETGEAR R7800 Router behind 5268AC gateway

I have the 5268AC gateway with my NETGEAR R7800 router plugged into the 1st LAN port and 2 TVs plugged into 2 other LAN ports and my VEN501-AT WAP plugged into the last LAN port for my two hardwired via CAT6 cable.

I've got the gateway radios off and all my wireless devices using the R7800 router as an access point. This isn't optimal since I can't use all of the routers functions.

Is there anyway in which the Uverse WAP VEN501 and the wired TVs can use my router vice the gateway?
