Orbi router to CenturyLink
Double NAT issue. I want to fix by using centurylink as modem in transparent bridge mode. However when I change that in the settings I lose the internet.

What is the MFr and model# of the ISP modem?
Cable or DSL?
Modem Combo Units:
Couple of options,
1. Configure the modem for transparent bridge mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly. If PPPoE, be sure your PPPoE account information is entered correctly into the Orbi router.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, LAN to LAN and configure AP mode on the Orbi router.

Did you power cycle both modem, router after the change, then also reboot your wired PC and wireless devices?
Also be sure to set the correct MTU value for DSL, maybe 1472 or 1492. Call your ISP and ask them what correct value they use and any bridging information help that maybe needed...

Thank you. Devices were rebooted. Still lose the internet light on the modem. Unfortunately Centurylink has the worst customer service. 2 chat sessions and a phone call and they were useless. Referred me to Netgear since their device functions and that's all they support.

First I would make sure that the modem is getting bridged correctly. Thats the ISP resposibility.
Review these as well:

I would do this, Take the Orbi out of the mix and connect 1 wired PC directly up to the modem while your getting the modem bridged and making sure it's correctly configured. Use your PC with the modem to test internet connection after you get the modem bridged. Use the PPPoE information on the PC as well where needed. If you don't get internet on the PC, then something with the modem bridging isn't working right. If you do get internet thru the PC, then reconnect the Orbi to the modem and the PC to the Orbi router. You'll need to make sure your PC is connecting correctly to the Orbi and not using the PPPoE connection.
