Model: Archer C80  
Hardware Version:
Firmware Version: Tether - newest

When i follow the guide and set everything up it just doesn't work. I have tried everything from changing or cloning MAC adress to changing LAN adress and setting the router as an access point. I really don't know what to do now. I don't know if i have a faulty model but it would only have to be the WAN port because i tried the LAN ports an they work fine. Thanks in advance

@Mik21  GOT IT!  like you said "if you change it into access point mode, and plug the ZTE H267A modem into one of the yellow ports on the C80". It worked. Thanks for the advice

May I know who is your ISP? What kind of modem are you connecting to the C80 router? Please follow this troubleshooting guide to check the basic settings again on the C80, and check if you can make it online:

Hi @Kevin_Z,

my ISP is O2, modem model is ZTE H267A. I have tried restarting it over and over but nothing helps because it says the WAN port is disconnected even tho i have tried multiple cables that i know function. I want to try one more thing today. I have seen that changing the MTU size from 1500 to something like 1492. I'm completely brunt out. Thanks for the reply.

Can I have the screenshot of the C80 Status page, does it display a WAN is disconnected? Do you mean the internet will work on the C80 if you change it into access point mode, and plug the ZTE H267A modem into one of the yellow ports on the C80? Did you configure the C80 into access point mode as per this guide (Case 2)?
