What access-point mode does
AP mode turns a wired network connection into a Wi-Fi access point. The extender needs Ethernet from the router or network, so this suits a room where cable can reach.

What Is AP Mode on a Wi-Fi Extender and When Should You Use It?
AP mode uses a wired Ethernet connection to create Wi-Fi. Extender mode links wirelessly to the router and repeats its network.
How extender mode differs
In range-extender mode, the device connects to the router over Wi-Fi and rebroadcasts coverage. It avoids a cable run but relies on its wireless link.
When AP mode makes sense
Choose it for a room with Ethernet installed or where you can run cable. It provides a local wireless access point without a weak wireless backhaul.
Check model support
Not every extender offers the same modes or port speed. TP-Link RE705X specifies a Gigabit Ethernet port and access-point mode. Follow the manual to select it.
Test the result
Connect a device nearby and check internet access. If the cable path or router setup is wrong, the Wi-Fi may appear without working internet.
