AP modes (advanced wireless settings):

• ap-bridge - Basic access point mode.
• bridge - Same as ap-bridge, but limited to one associated client.
• wds-slave - Same as ap-bridge, but scan for AP with the same ssid and establishes WDS link. If this link is lost or cannot be established, then continue scanning. If dfs-mode is radar-detect, then APs with enabled hide-ssid will not be found during scanning.
