WiFi Access Point vs Extender: How the Setups Differ

An access point creates WiFi from a wired network connection. An extender usually repeats the router's WiFi wirelessly, though some models also offer Access Point mode.

No, they describe different network roles, but a product can support both. Check its mode list and the connection each mode requires.

An access point is a strong option when Ethernet reaches the location. A range extender suits a local coverage gap when cabling is impractical and its router link is good.

The terms are often used for devices that relay an existing wireless network. An access point differs because it typically receives its network over Ethernet.
