Abstract: Devices, systems and methods are disclosed for enabling a device to act as a wireless extender and adaptively control a transmission power for capability messages. For example, when the device has the capability to relay traffic without affecting a local processing of the device, the device may transmit capability messages at a normal transmission power and may relay traffic between a network device and clients. However, when the device no longer has the capability to relay traffic without affecting the local processing, the device may transmit capability messages at a reduced transmission power. As clients use the capability messages to determine a signal strength of an access point, the reduced transmission power results in the device appearing to have a lower signal strength and thus decreases a desirability of the device as an access point.
