I'm sorry if this has already been asked & answered, but I was not able to find it.

I am dumping my old cable company modem/wireless router and cable TV, So I need a new wi-fi system.  I believe the M5 and the Netgear CM700 I got will do the trick.  My concern is how to connect my main computer to the system.  My thought is that i will connect it or a laptop to the cable modem to get it setup.  After the modem is set I can disconnect the computer, connect the server M5 to the modem and setup the mesh wi-fi for my home.  I am planning to then connect my main computer to the server node.  Will this work?   Or will I need to set the server node to AP mode?   Or do you suggest something else?

My Home is 1440 sq. ft.  My cable connection is on the far east side of the house.  I think I will only need 2 (two) of the M5 nodes to cover my home.

Thank you
