Is it possible to set up a second router to work off the TG589vn (the one you get when signing up with VDSL with Telecom) without putting it in Bridge mode?

Recently bought a dual band TP-Link WDR4320 and would like to keep it (plus having the 5GHz option is nice)

I'm under the impression that you can using DMZ.

While it would be easier to just put it in bridge mode, I'd like the better coverage of two routers since our place is quite big and the Thomson/Technicolor alone doesn't penetrate to all the rooms in the house.

Basic idea is:

TG589vn ))) Wifi (2.4GHz - Channel 11) ----LAN---- PC1
|

LAN
|

TP-Link WDR-4320 ))) (2.4GHz - Channel 6, 5GHz) ----LAN---- PC2

Trouble is, I can't get the TG589vn to identify the second router when I plug it in (so can't assign a public IP).

Any suggestions on this front?

Yes, the TG589 supports a DMZ, but the device in the DMZ must be a DHCP client. The TG589 will assign it's public IP as the DMZ client's DHCP-allocated address. It's quite effective, and you can still access the TG589 via it's LAN IP if needs be. This also means the other router has to support a DHCP-allocated WAN IP.

That said, what you're doing looks more like you simply want a second access point, so just plug a LAN port on the TPLink into  a LAN port on the TG589, make sure they're both on the same subnet (but not the same IP!) and you should be away - only do DHCP on one though.

But if you want to proceed with your plan outline, well, doing this will have each of your PCs on a separate LAN, and you will need to have routing between them configure. This will also mean NAT traversal between your PCs. If you really mean you want to use the TG only as a modem and use your TPLink for routing etc, you'd be better going for

I would disable dhcp off your second router. Also change the ip address and make sure it's not 192.168.1
254 or .253. Then plug the router into the lan port then you should be away.

Yep what Pete says above.

You don't need to use DMZ or bridging for this situation.

The setup you want is typically called "WAN Bypass" because you are bypassing the WAN port on the 2nd device (the TP Link in your case) and using it as a network switch + wifi access point.

In the TP Link
1: Disable DHCP
2: Set it's LAN ip address to something the same network as the Telecom Technicolor/Thomson is giving out also something not already in use
3: Connect via network cable from LAN port on the Telecom to LAN port the TP Link.
4: Profit

Awesome, thanks guys :D

Inphinity or Ragnor, by LAN port, do you mean the 1-4 LAN ports (yellow) or the ethernet port for PPPoE (blue) in the image below?

I'll try this out when I get back from work.

My thinking was that as long as there wasn't a conflict in the DHCP pools that was ok and ultimately desirable so that the primary router wasn't assigning IP addresses. I guess I was mistaken.

Yellow LAN ports.

If you run two network ranges one on each device and both are running DHCP traffic coming from behind the TP Link has to traverse NAT twice which can break lots of things, especially gaming.
