How can I make settings to support DHCP IP assignments and also recognize my manual IP's assigned to the LAN connected devices?
The easiest way I can think of is to shrink the DHCP address pool.
To do that, at least on the model of Actiontec router I have, click on "Network (Home/Office)" the go to the "IP Address Distribution" section of the screen. "DHCP Server" should already be selected, and under that, you'll find "Start IP addresses" and "End IP addresses." Usually, the start will be 192.168.1.2 and the end will be 192.168.1.254. What I usually do is change the start address to 192.168.1.200. That leaves over 50 addresses for normal wireless connections, and I'll general assign IP addresses from the rest of the range as follows:
192.168.1.2 to 192.168.1.9: routers, APs, etc.
192.168.1.50 to 192.168.1.59: printers
192.168.1.100 to 192.168.1.109 for other static devices. (I often find that Blu-Ray players, cable boxes, etc. behave better if they have a static address.)
But really, on home network, I doubt you'll have more than 15 devices that need static addresses, so you could set the DHCP start address as low as 192.168.1.16 if you wanted to.
