@coxhaus okay got it all figured out (refuse DHCP to unrecognized MACs, and firewall rules to block IPs outside of your range.) this worked very well and I was able to use the Access Control on the netgear as well so that WIFI clients could not connect either.
I am now completely up and running, I have addressed my speed issue by just getting Intel (ET PRO 1000) dual Ethernet adapter and just disabled RealTek Nic's. I am now getting the speeds I am paying for and I can see that everything inbound is block, no new devices can connect very happy camper here,
