I’ve got the modem correctly set up and working and I have both wifi and internet coming from it. I am trying to connect my router (TP-Link Archer C-50) to the modem via an Ethernet cable by connecting the WAN ports of the Modem and the Router. The router is working but the internet icon is flashing in red light and I have wifi from the router but no internet connection.
I am following this tutorial by TP-Link and I got to step 3, but I don’t know where to find the ISP username and password:
I am not sure if this will solve the problem or I am searching in the wrong place but any help is appreciated!
