It looks like your DSL modem is also a router. You will still need the Zyxel as it pulls the internet from the DSL line, you would then connect your TP-Link router to the Zyxel. 

Customers would typically set their modem to bridge mode so it just passes the internet connection through it, and then set up the PPPoE login info on the router which it will then receive internet.

Here is a FAQ that shows a setup with a DSL modem: https://www.tp-link.com/us/support/faq/713/

Hi Tony,

I appreciate the reply, but this is not correct.  There is no DSL modem involved.  As I said, I am using fiber.  No DSL modem involved.  

The Zyxel is just connecting via PPPoE.  I should be able to replicate this on my Archer C9.  I think the issue is that I need to also set VLAN tagging, but I can't find that option on my Archer C9 v1.

Going back really quick to the IPTV. You should find that by logging into the TP-Link router and going to Advanced > Network > IPTV. You can set the following VLAN numbers, make sure to check 802.1Q Tag to the right.

If that does not work, you can try changing the configuration of the Zyxel to be a bridging device. Here is a link to the process it shows how, under transparent bridging. This involves modifying your ISP device so it would be best to contact them to see if it is possible to do that to avoid any issues:

Please provide a screenshot of what you are seeing.

Any ideas?

I was able to change mine to IPTV

@Praxis  I had same problem with TP-Link Archer A7:  the PPPoE auth to CenturyLink would not work. Solution was indeed to enter the VLAN settings that are found in the picture in this thread.

I found the settings here in the admin console:

- Advanced (top tab)

- Network (left nav)

- IPTV/VLAN (sub left nav)

Then, following the picture found in this thread, I changed these settings:

- checked Enable IPTV/VLAN

- Mode = Custom
- Internet VLAN ID = 201
- IP-Phone VLAN ID = 202
- IPTV VLAN ID = 203

- Also checked "802.1Q Tag"
 

Then it worked! Glad I found this thread.
