Archer A7 WAN connection error

Model: Archer A7
Hardware Version:
Firmware Version:

Archer A7 router connected to an Arris SB6141 modem. 

 

When modem is connected to the PC directly, I have internet. 

When I take the same cable and connect from modem to router, the Archer internet LED becomes orange (internet cannot be connected) and I get a WAN connection error during setup: 

Unable to obtain IP address from the DHCP server. 

 

I tried resetting both the modem and the router, now I cannot complete the router setup. 

 

Any advice?

Since the PC worked connected to the modem, I would not suspect the modem. Check out this thread https://community.tp-link.com/us/home/forum/topic/150603 as it may help.

@ArcherC8 

Thanks for your reply. 

I ended up following instructions here and eventually it worked (seems like I had to try it 2-3 times): https://community.tp-link.com/us/home/kb/detail/231
