Hi Furry, Thanks for reply. There is no WAN port on C7000, so I tried to like this , 1Gig Fiber cable -> Centurylink modem router (ZyXEL C3000Z) WAN Centurylink modem router (ZyXEL C3000Z) LAN to C7000 LAN C7000 LAN to my mac Then speed around ~250.

the C7000 doesn't support router only mode. It is a modem/router combo device. You can disable the router aspect of it  to function  as a modem. Not the other way around. 

There's a work around on this forum for C6300 that would be similar. https://community.netgear.com/t5/Cable-Modems-Routers/Can-I-use-a-C6300-cable-modem-without-cable-internet/m-p/1463500

It doesn't mean you'll get the performance of a router only if you get it working. Its just a way to maybe make it function decently and without a double nat situation.
