I think there are load balance router which has ADSL/VDSL ports too but it would be insanely costly.

Maybe the below diagram will help you clear the doubts.

My already installed TP-Link wifi router doesn't need to be changed then?

 

[Nishant]

Is that an ADSL router or you have an ADSL modem separately which is connected to a normal Wifi router? Can you post the model number here?

if your router is a combo device, it would be wasted as it would be behind the load balancing router. best is to get two modems and one wireless router and put the load balancing router in the middle as in the diagram.

It's a combo

Putting this behind the load balancing router would be waste. I suggest buying two plain ADSL modems like this and then use the above wireless router in access point mode. The wireless router should have a setting to turn it into an AP.

So then load balance router is out of situation? And still both connection will be merged via my wifi router in AP mode?

 

[Nishant]

No. Load balance router will come in between those two ADSL modem and Wireless router (acting as an AP) as shown in the diagram I posted.

see your second connection would need its own modem and router or a combo device like the one you already have.
you cannot merge two connections using a wireless router or the device you already have.

so your option is to buy two modems (around 800 each) and one load balancing router (3500). and use your existing combo device exclusively as a wireless router.
