Abstract: In one example in accordance with the present disclosure, a network device may include a processor to announce radio information of the network device and neighbor network devices adjacent to a client device; to establish a first wireless link operating on a first frequency band and a second wireless link operating on a second frequency band between the network device and the client device; and, to cause the client device to switch the second wireless link from the network device to a neighbor network device, while the first wireless link connected to the network device being active.

Abstract: An example network device may include a processor to receive information of a set of devices including at least one network device; estimate interferences of available basic service set (BSS) color values in a specified channel, based on the received information; and select one BSS color value with the interference lower than others from the available BSS color values.

Abstract: An example device comprising: a processor to detect a time difference between a first system clock of an access point (AP) and a second system clock of a controller; determine whether the AP has abnormal dock based on the time difference; and automatically recover the first system clock of the AP when the AP has abnormal clock.

Abstract: The present disclosure discloses a method and network device for measuring wireless link quality. The disclosed network device retrieves a plurality of packet transmission data corresponding to a plurality of transmission rates at which packets are transmitted over a wireless link between two wireless nodes in a wireless network. The network device also determines a wireless link quality metric value corresponding to the wireless link at least based on at least an average throughput associated with the plurality of transmission rates. The wireless link quality metric value can be further based on a maximum throughput corresponding to a hardware component in at least one of the two wireless nodes. The wireless link quality metric value can be used in monitoring or managing the wireless network.

Abstract: The present disclosure discloses a method and digital device for improving performance in discovery stage of fast roaming. A disclosed digital device switches from a first wireless communication channel to a second wireless communication channel; transmits, on the second wireless communication channel, a request message comprising a designated field; and switches from the second wireless communication channel to the first wireless communication channel prior to receiving a response message corresponding to the request message on the second wireless communication channel. A network device receives the request message from a client device on the second wireless communication channel. The request message is associated with a first signal strength level.
