The verdict
These are dual-mode extender products rather than dedicated access points. Use wired AP mode where cable is practical; choose wireless range-extender mode when installation simplicity matters.
Wired backhaul: TP-Link RE605X
Both products list access-point mode and a Gigabit Ethernet port, so either can serve as an AP when cabled to the router.
Wireless relay without running Ethernet: TP-Link RE550
Both support range-extender operation; RE550 uses AC1900 dual-band Wi-Fi and three adjustable external antennas.
Wi-Fi 6 clients: TP-Link RE605X
TP-Link identifies RE605X as an AX1800 Wi-Fi 6 extender.

Common questions
Questions before you buy
Is an access point better than a WiFi extender?
A wired access point often provides a more direct link to the router, while an extender can reach a nearby area without new cable. Layout and backhaul options decide which is suitable.
Can a WiFi extender be used as an access point?
Some models offer AP mode. TP-Link RE605X and RE550 list AP mode and Ethernet ports in manufacturer information.
Is a WiFi repeater the same as an extender or access point?
Repeater and extender often describe wireless range-extension roles, though terminology varies. An access point creates Wi-Fi from a wired network connection.
Which is faster, an access point or extender?
There is no universal speed result. A wired backhaul can avoid the wireless relay hop; actual throughput depends on the router, client, interference and product capabilities.
