Simply set in the router the DHCP range your want. Anything outside that range is a static IP. For example set the DHCP range in the router to 192.168.1.100 starting, 192.168.1.150 ending. The router...

Well MAC filtering is useless for security anyway. Can be hacked in 5 minuets.

I don't think so. That would defeat the purpose of the MAC filter.

Well if you disable the DHCP server in the router how is the Wireless going to connect and give you an IP address????

Go back into the router and change the password to something else. Make sure you have different SSID names also for all bands.

I have the Archer C7 and there is nothing like that at all.
