centurylink + airport extreme how to setup? bridge? nat?

[x-evil-x]

My system is setup on double nat as of now. I have a cable modem with wireless disabled and centurylink normally uses pppoe standard on the router. How should i set this up so i don't have issues?
My 2.4 ghz channel doesn't get half of what the 5ghz channel gets and i just got a new cable modem. Anything i should do? it is showing connected to 802.11ac on my new mac
Thanks for you help

The rule of thumb in home networking is if it is behind another router should have NAT disabled because on the main router still doing NAT! This is to get the quickest speeds to prevent network collisions!

In Apple routers to turn off NAT put the Extreme/Time Capsule just put the router into "Bridged Mode"!

I tried putting it into bridge mode but it wouldn't work. Not sure what other setting I need to do on the century link side

To run the CL modem in Transparent Bridge mode, you need to have your pppoe login credentials. These may or may not have been provided to you by the installer. If you have them, put the modem in Transparent Bridge mode, and set the Apple device to do a pppoe login, using those credentials.

I just got the credentials last night. I will try today. Do I turn the CenturyLink side to transparent bridging then put pppoe into the airport settings? Or do I make a pppoe on network preferences setting?

Look at this older blog at Apple Stack Exchange How To with some pictures!

according to that the airport should be showing DHCP and NAT once its in pppoe settings and not set to bridge mode.
The century link is the one set to transparent bridge mode I'm guessing and the airport has those settings.

i got everything to work. Had to go through the MacBook to do it then somehow got it to recognize on the airport after a few tries.
One thing that doesn't work is ipv6. I don't know if i have to enable it in the settings for century link it seems like its all on from the airport router. When i test it i don't get that its enabled .

Also when its connected to pppoe from the airport it should be on DHCP and NAT correct?
