My ISP already provides a modem-router hardware, so I need to configure my Archer C9 as an access point.
So
- I do not use the WAN port: I plugged my ISP router in a 1GB LAN port;
- I disabled the DHCP server on the Archer;
- I set a static IP address with the correct subnet mask and gateway.
Despite everything is working fine, I am unable to log on the Archer admin page. Furthermore, the Archer does not appear as connected to my ISP router admin page.
