Hi, thanks for posting question on our community.

The TP-Link Archer Router operates in Router mode by default, functioning as a gateway device with features like Antivirus/Protection, Parental Controls, QoS, and DHCP Server. However, users can choose to switch to Access Point Mode when they already have an existing router serving as the gateway device, and they simply need the Archer Router to provide Wi-Fi access.
To change your TP-Link Archer Router to Access Point Mode (AP Mode), please follow these steps:
1) Connect the TP-Link Archer Router to your existing Router, connect your PC to the TP-Link Archer Router through Ethernet or Wi-Fi.
2) Access the web management interface by opening a web browser and entering "tplinkwifi.net" in the address bar. Log in to the interface.
3) Navigate to Advanced > System > Operation Mode. Select "Access Point Mode" from the options and save the changes.
4) Alternatively, you can use the TP-Link Tether app. Download and open the app, log in to your router, and go to Tools > Operation Mode. Choose "Access Point Mode" and apply the changes.
5) The router will reboot and switch to Access Point Mode.
Note:
When you switch to Access Point Mode (AP Mode), certain gateway features will no longer be available, including QoS, Parental Control, DHCP Server settings,  IPTV,  VLAN, and DDNS, etc..
For more detailed information on the differences between Router mode and AP mode on TP-Link routers, you can refer to the FAQ.
