Model: Archer AX1800  
Hardware Version: V3
Firmware Version:

After working for a day, the router has decided to stop detecting my modem's WAN cable. The modem lights for the connection won't pop up when I plug it in, but when I plug my  PC directly into the modem it works just fine. When I plug the cable in, it allows me to pull up the TPLink setup page to manage the router, but doesn't actually transmit internet. 

Things I've tried over the last day:

 

Reseting my computer/modem/router

 

Changing the dynamic ISP to a static ISP

 

Changing internet speed to 1,000 Mbps from the router page

 

Changing the DNS address to 8.8.8.8 and 8.8.4.4, respectively

 

Changing the mode off of and back to "bridge" from the router page

 

Changing out at least 4 LAN cables, all of which are the proper type

 

Both updating and rolling back the firmware (currently on 1.1.1)

 

Cloning the MAC address. 

 

 

I'm really reaching my wits end on this one guys. My auto detection IP settings are all at 0.0.0.0

Suspect you are but getting an IP address from your modem. See the very first post for the solution.

Just attempted that, unfortunately no dice. The connection lights on the back of the modem are still off

@ScribeSlendy 

 

Can I confirm who is your ISP, and what is the Connection Type provided by them, is it Dynamic or Static?

 

What if you connect the modem LAN to the LAN of the AX1800, will the modem detect the AX1800? 

 

To assist and figure it out efficiently, I've forwarded your case to the TP-Link support engineers who will contact you with your registered email address later. Please pay attention to your email box for follow-up. Thank you.
