Found another router on the network but I have only one router

I have a Archer C80. Wireless router modem, that supports PPOE. I have been using it for more than an year and it was completely fine. Today I reset the modem ( dont ask me why , am stupid ).
I setup the connection, everything was fine , but before the last screen there was error stating
" Found another router " and it gave me three options
- Modem and Router separate
- Modem and Router together
- None
tried all 3. The router says connected, the IP address is assigned but am not able to use the internet. Breaking my head. Same internet, same credentials , same device , just a reset and I dont know what went wrong

Hi @cyndrome,
Sometimes your ISP might provide you with a modem/Router combo device instead of a pure modem. Under that circumstance, if you connect your TP-Link Archer Router/Modem/Deco into the ISP Modem/Router, there will be double NAT issues.
With double NAT, establishing connections with external servers become harder, which is not friendly for online gaming, video conferencing, etc.
We have the following two methods to resolve double NAT issues:
1. Change your Modem/Router combo device into bridge mode, in this way, the TP-Link Archer Router/Modem/Deco would be directly obtaining IP address from your ISP, not the modem/Router combo device.
2. Change your TP-Link Archer Router/Modem/Deco into Access Point mode, in this way, your ISP Modem/Router would still be the main Router, the TP-Link device simply becomes an Access Point device, providing Wi-Fi network only.
We highly recommend using method 1 instead of 2, when you use your TP-Link device as the main Router, you are able to experience its advanced features like parental control, HomeShield, QoS, VPN, etc.
However, those features will not be available in Access Point mode.

Archer C80 is only a wireless router - there's no modem in it. These screenshots are not particulary useful.
Describe your network devices (including ISP provided if there's any) in more details to be advised:
What's the Archer C80 WAN IP address, what's its LAN IP address ? Do you have any ISP router/modem?
