Overlapping BSS (OBSS): If the channel width is set to 40MHz or 80MHz and the AP property Active OBSS channel width adjustment is enabled, the AP shrinks its channel to avoid overlapping with other APs detected in the area. (An OBSS overlap occurs when a primary channel and a secondary channel overlap.) After the interfering AP is shut down and the AP’s radio is reset, the channel width returns to 40MHz or 80MHz.
- When setting a fixed channel width to 40 MHz or 80 MHz, the Active OBSS channel width adjustment setting must be disabled.
- This setting is disabled by default for existing APs in order to maintain existing behavior and the existing channel plan. For APs that are newly added to the network, this setting is enabled by default.
- AP39xx and AP38xx perform overlapping BSS (OBSS) scan every time the radio is restarted
- The OBSS setting has no direct correlation to Auto Channel
