WDS vs R (Repeater) vs RB (Repeater Bridge)

This is my summary of issues related to repeating using "WDS" vs "Repeater" vs "Repeater Bridge" modes. Please note that some lines require to be confirmed ("TODO: Confirm"). If you experiment other results than those here indicated, please add your comments providing also your HW and DD-WRT version.

  • On both WDS and R/RB (both R and RB), the repeater can broadcast another SSID. On WDS with WPA, both routers need to have the same SSID (TODO: Confirm).
    • On WDS, both routers need to have the same SSID, which will be broadcasted by both routers (TODO: Confirm).
    • On R/RB, the physical SSID will not only be used for joing the main-router, but also be repeted by the repeater (TODO: Confirm).
    • On R/RB, two SSID with the same name will collide (give problems) (TODO: Confirm). If not, having the same SSID on the main-router and the repeater allows to "roam", ie. keep a connection active ¿or reconnect? (TODO CONFIRM) when a client nears the other router.
    • After RC6.2, virtual interfaces have BSSID with MAC address 02:00:00:00:00:01. If the main-router and the repeater broadcast a BSSID with the same MAC, they probabilty will collide (TODO: Confirm).
  • WDS and R/RB both will reduce bandwith to half (TODO: Confirm).
  • WDS must be configured on both routers (requires access) and require a compatible WDS implementation. R/RB only needs to configure the repeater and doesn't rely on the main-router's HW or version.
  • WDS does doesn't support WPA2, it can be setup, but is just ignored (TODO: Confirm). R/RB support all encription alghoritms.
  • WDS supports building a network of routers, where a repeater can connect to multiple other "main-routers" (WAN-routers) at the same time (TODO: Confirm). R/RB only connects to one router at a time. Any way, both support connecting repeaters in series ("repeat a repeater").
  • WDS does not perform MAC address translation (MAT). R/RB does translate MACs : the main-router sees all connections from clientes which connects through the repeater belonging to the same MAC as the repeater. This causes problems with some applications which relies on a MAC address.
