Architectures and techniques to manage resources in a wireless access point. A first set of weights is associated with connected wireless client devices. The first set of weights includes at least one weight for each of the connected wireless client devices. Space is allocated within the packet monitoring buffer to capture packet information for the connected wireless devices using the first set of weights. An indication of an event of interest is received. A second set of weights is associated with the connected wireless client devices. The second set of weights includes at least one weight for each of the connected wireless client devices in response to the indication of the event. Space is allocated within the packet monitoring buffer to capture packet information for the connected wireless devices using the second set of weights.

Dynamic resource allocation in a wireless access point to support event capture

An apparatus may comprise a processing resource operatively coupled to a memory resource and a frame determination component operatively coupled to the processing resource and the memory resource. The frame determination component may cause a counter corresponding to a particular station associated to the apparatus to be stored in the memory resource, the counter to be incremented in response to receipt of a transmission frame containing an invalid starting sequence number (SEN) and a deauthentication frame to be transmitted in response to receipt of a threshold number of transmission frames containing the invalid.

Transmission frame counter

An access point providing a client device with access to a communication network detects an anomaly in packet traffic being transmitted to or received from the client device. In response, the access point performs a packet capture by triggering the release of stored packets. The access point determines an anomaly type representing a root cause of the anomaly and annotates the packet capture with the anomaly type. The access point also detects radio frequency interference exceeding a prescribed threshold and, in response, performs a spectrum capture. The packet capture, annotated with the anomaly type, and the spectrum capture are reported either automatically or in response to a request.

Anomaly-driven packet capture and spectrum capture in an access point

An example access point may include a memory and a processor executing instructions from the memory to receive an instruction to start a scan on a different wireless communication channel than an operating channel of the access point; transmit a Clear To Send-to-self frame on the operating channel of the access point, to notify client devices associated with the AP and at least a neighboring AP that the operating channel is busy, wherein the control frame includes a basic service set color associated with the access point; scan on the different wireless communication channel subsequent to transmitting the Clear To Send-to-self frame; and defer a subsequent data transmission received from the client devices in response to the data transmission including the basic service set color associated with the access point.
