My ISP already provides a modem-router hardware, so I need to configure my Archer C9 as an access point.


  • 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.


Shortly -

  1. assign a unique static IP to the router's LAN interface so it won't overlap with the main router/gateway or it's DHCP pool. To avoid address conflicts make a static DHCP provisioning on the main router DHCP for the C9's new LAN address, e.g.
  2. disable C9's DHCP
  3. connect C9 via LAN but not WAN port

  • That is exactly what I did and it worked fine. Thanks a lot for your answer! – Larry Oct 26 '16 at 8:43
