Use internet on TV with router as wireless bridge

Attached image has a setup of what I want to do.

My DSL modem is working fine and has internet access. I can connect to internet using Wifi on my phone and other devices.

The TV is an LG TV which supports internet using an accessory (Wifi dongle) or Lan cable. The accessory is out of stock in market and a LAN cable from my DSL modem cannot make it to the TV.

So I am trying to use a second router that tries to connect as wireless bridge to my DSL modem but no success.

The router is of TP-LINK model TL-MR3220. It has a USB port that supports connecting from 3G modem and an uplink ethernet Port. Means 2 ways of getting an internet connection.

I am not sure if it is possible to connect to internet using the wireless bridge as I have tried to configure it that way with no success.

I suppose the setup I am trying to use is not supported as the router only offers 2 uplink ports to internet (USB or LAN). It could be possible using static routes.

I need to keep the router on a different network as it needs different networks for LAN and WAN else it throws a configuration error.

So any ideas to get it to work?

The router is a transmitter & not a reciever.
I would suggest getting a longer LAN cable to reach the TV as the most simple & practical solution.
Or wait untill you can get the Wifi dongle.

Agreed, but can you shed some light about WDS -Wireless distribution system on the router under wirelss settings. Why does it even exist if it is not a receiver in some sense?

The router is a transmitter & not a reciever without a PC to setup & control a wireless network.
You would need to include the TV in a network for the router to recieve (such as a wireless network can do)
The TV cannot control or set up a wireless network for the router.
(it can only recieve internet)
Router-PC-TV cable connected & set up correctly would work, but your TV supports internet using an accessory (Wifi dongle) or Lan cable...so to connect it via a PC kind of makes no sense.

You are probably not getting my Q right in the first place.

The TV supports getting dynamic IP via DHCP that is done by the router.

I need to get the second router to hook up to the Adsl-modem-cum-router's internet which would be NATted to the TV.

If you do not require 3G support on the device, I suggest flashing it with DD-WRT which will provide you the ability to perform Client Based Bridges. This means that your AP would disable it's WAN port as well as DHCP, connected to your Wireless Infrastructure as a client and pass through the wired ethernet ports as a switch. This would allow all devices in your network to continue to operate on the same Layer 2 environment.

One thing worth noting though, I noticed that the AP you are working with is a BGN only AP. You need to make sure that your DSL Model is B/G Compatible. It will not work if it is A or even A/N since they two would operate in a different frequency spectrum.

Correction:
Wireless network connected PC-TV cable connected & set up correctly would work.

The TV needs to recieve internet via a Wifi dongle or Lan cable.
The TV cannot control or set up its own wireless network or control a router connected to it.

I may be wrong about  your TVs capabillity but do not think so.
 
Its late where I live (Tokyo) so shall say goodnight & sign-off

This may help explain:

I thought of it too, but will spend some bucks and go for additional hardware as this is a pretty new router originally purchased to indeed share 3G internet.

So, time to figure out if the router supports Client Based Bridging. Will have to dig into the manual though, which I did but did not quite get to understand how it was implemented. jgibbar, probably you are following what I want to do and where I am failing.

 Thanks a lot,

I don't want to hurt you in any sense but I am an expert myself here at E-E, (though with not that many points as you have gathered, since I stopped participating for the past 2 years or so) and am quite familiar with networking. Wrote an article regarding networking here .Presently I am running an LG electronics Shoppe and know the TV's capabilities quite well, since I successfully managed to run a similar setup via a wireless Blu-Ray player.

what is the model of the LG Internet TV?

http://www.lg.com/in/tvs/lg-32LM6200-3d-tv is the model of the TV. It is a new launch from the company.

However, my router needs to get connected to adsl modem to share internet with the devices connected to it. I have not been able to get internet output from the second router.

Router doesn't probably support Client Bridging which is what I am trying to do.

Customer Care of TP-Link was not reachable. Probably the WDS option is to share devices of some other wireless network (provide only LAN sharing and not internet sharing) - more of an ad-hoc type network.

So guess what I am trying to establish won't work due to limitations of Router Firmware.

So, closing the Q and awarding points.

Everybody was a great help though.

Unable to establish connection due to limitations of router firmware. Client Bridge was needed to provide internet to the TV but the router does not support client bridge mode.

Awarding points to jgibbar for specifying need of client bridge in the network setup.
