Abstract: Examples described herein relate to an investigator device and a method for determining a condition of an antenna of an access point (AP). At least one investigator device may receive one or more antenna condition test frames transmitted via a plurality of antennas of the AP Further, the at least one investigator device may determine an average received signal strength indicator (RSSI) value corresponding to each of the plurality of antennas based on the one or more antenna condition test frames. A condition of the plurality of antennas of the AP may be determined based on a relative comparison between the average RSSI value corresponding to each of the plurality of antennas of the AP. Moreover, in some examples, the at least one investigator device may send a notification to an administrator of the AP based on the condition of the plurality of antennas.

Abstract: Examples of techniques for handling unsolicited probe responses are disclosed. In an example, occurrence of an attack on an access point (AP) in an enterprise Wireless Local Area Network (WLAN) is detected based on an unsolicited probe response and Robust Security Network Information Element (RSN IE). Responsive to detecting the attack, unsolicited probe responses at the AP is disabled. Further, Fast initial Link Setup (FILS) discovery at the AP is enabled.

Abstract: A method for protecting 802.11 ax networks includes receiving, by an access point, a plurality of Single User (SU) Quality of Service (QOS) NULL frames from a station, tracking, by the access point as the plurality of SU QOS NULL frames are received, a variable in one or more of the plurality of SU QOS NULL frames, determining, by the access point and based on tracking the variable, the station is suspicious, sending, by the access point and in response to determining the station is suspicious, a request to check a status of the variable, determining, by the access point and based on a response to the request, the station is under attack, and flagging, by the access point, the station as under an attack.

Abstract: Examples of block acknowledgement negotiations are described. In an example, a request to establish a BA session is sent by a first computing device (first device) to a second computing device (second device). A timer for receipt of a response to the request is initialized. A BA successful response is received by the first device after the timer has timed out. A request to terminate the BA session is sent by the first device to the second device. After sending the request to terminate the BA session, BA negotiation is reinitiated by the first device based on an updated inactivity timer, so that there are greater chances of successfully establishing a BA session. In an example, if the second device ignores the request to terminate the BA session then it sends a BA reject response to the first device. After receiving the BA reject response, the first device waits for the inactivity timer before reinitiating BA negotiations, so that the second device clears its states thereby increasing chances of successful BA renegotiations.

Abstract: An example method for providing enhanced wireless connectivity to client devices is presented. In one example, an access point is configured to monitor management frames it receives and determines if any neighbor AP advertises an unexpected regulatory setting (e.g., country code), and take corrective action if it is determined that the neighbor AP advertises an unexpected regulatory setting. In another example, a network device may be configured to manage a mobile country code (MCC) of the client device by transmitting an executable application. The executable application may ensure that the client device implements the right regulatory configuration. The proposed techniques may prevent the client device from switching to an incorrect regulatory configuration, thereby enhancing the wireless connectivity for the client device.

Abstract: An example method of allocating channels to access points (AP) is presented. A network manager may determine weights of the APs based on a channel metric and a location metric for APs. Further, the network manager may identify a first set of APs based on the weights and allocate a dedicated first channel to each of the first set of APs for its sole use. Accordingly, each of the first set of APs may use a respective dedicated first channel thereby reducing the performance impact on other APs. Further, the network manager may identify a second set of APs based on the weights and allocate second channels for sharing among the second set of APs. Since the second set of APs does not share any channel with the first set of APs, the performance of the second set of APs may not be impacted due to the first set of APs.

Abstract: Examples described herein relate to a method for managing association of a client device with a virtual access point (VAP) hosted on an access point (AP). The method includes monitoring, by the AP, data traffic corresponding to the client device associated with a first VAP. The first VAP is mapped to a first Multiple Basic Service Set Identifier (MBSSID) set configured with a first quality of service (QoS) parameter. The AP also hosts a second VAP mapped to a second MBSSID set configured with a second QoS parameter. Further, the AP determines a communication demand of the client device based on the data traffic. Furthermore, the AP steers the client device to the second VAP based on the communication demand and the second QoS parameter, and communicates with the client device through the second VAP.
