Unable to make pppoe connection

[deb]

I tried to connect the adsl cable directly on my tp-link router and I got no success.
My network looks like this:

Of course not, your WR1043ND does not have a DSL modem. Its WAN port is an ethernet port, not a modem port.

If your ISP's modem-router itself now cannot make a connection anymore either, I would reckon something's wrong on the ISP's side.

Oh! My bad.
My isp also suggested that when setting their router in bridge mode they disable the modem for internet and let it only for telephony (voip). So my device should also be a modem/router.
I thought i would be capable to use the tplink.

edit: finally I managed to speak with someone from my isp and they suggested a few bugs on their device so I asked for a replacement. I'll update when I test with the new hardware.
