Hi all,

I bought this TP-Link Archer C6 v 3.20 US about 2 weeks ago. From today, I am not being able to connect this router over PPPoE or dynamic IP to the internet. 

What I have done so far is-

- updated to the latest firmware

- done factory reset of the router several times

- checked the ISP connection with a different router and the connection works fine with another router

- tried to connect via dynamic IP from a different router but it did not connect

While connecting with the internet from Archer C6 v3.20 US, it repeatedly shows "failed to establish internet connection".

What can I do to solve the problem and get the router working?

Thank you.
