No, because your WAN interface has "connected" status.

OK thanks for all your help. I'm lost really

Can you show me addresses from your network card when you have connection with TP-Link and next time with your ISP modem for compare?

To be honest I don't know what I'm doing

ipconfig /all in cmd

Do you mean the WAN addresses listed by each of the two routers?

Here are the only differences I can identify between the two ipconfig outputs:

Everything looks OK,
The last test, when you have TP-Link connect please check command ping 8.8.8.8 in cmd
