Publication number: 20240098493Abstract: Techniques for identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network, a first network message is received from a first access point (AP) identifying a first service set identifier (SSID) associated with a first wireless network, a second network message is received from a second AP identifying a second SSID associated with a second wireless network, and a visual similarity is determined between a first visual representation of the first SSID and a second visual representation of the second SSID. The second SSID is designated as suspicious based on the determined visual similarity.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Inventors: Jay K. JOHNSTON, Jerome HENRY, David C. WHITE, JR., Magnus MORTENSEN, John M. SWARTZ, Robert E. BARTON

Publication number: 20240064609Abstract: Techniques for wireless communication are disclosed. These techniques include determining that a first wireless access point (AP) has a failure to connect to a controller. The techniques further include identifying one or more neighbor APs, for the first AP, as candidate rescue APs, selecting a rescue AP, from among the candidate rescue APs, and establishing a secure connection from the first AP to the rescue AP. The techniques further includes transmitting diagnostic data from the first AP to the controller using the secure connection from the first AP to the rescue AP.Type: ApplicationFiled: August 16, 2022Publication date: February 22, 2024Inventors: Jerome HENRY, John M.

Publication number: 20240030599Abstract: Embodiments herein describe mounting one or more lasers onto an AP to generate a laser pattern on a surface representing the coverage area of an antenna in the AP. In one embodiment, the antenna is a steerable antenna that can be electronically or mechanical steered to point to different directions (without moving the AP as a whole). The laser or lasers can be used to visualize the coverage area of the steerable antenna when pointing in different directions. Advantageously, a technician can use the laser or lasers to identify a location where, if steered, the antenna would provide the desired coverage area. The technician can then steer the antenna to point in that direction to provide the desired radio frequency (RF) coverage.Type: ApplicationFiled: July 20, 2022Publication date: January 25, 2024Inventors: Fred J. ANDERSON, Jonathan M. CYPHERT, John M. SWARTZ, Daniel N. JOHNSON, Danielle N. BANE

Patent number: 11877154Abstract: Techniques for identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network comprising a service set identifier (SSID), a network message is received at a wireless station (STA), from an access point (AP) associated with the wireless network. The STA identifies an encrypted identifier in the network message. The STA validates the encrypted identifier, and in response determines that the AP corresponds to a trusted wireless network. The SSID is designated as trusted, at the STA.Type: GrantFiled: March 5, 2020Date of Patent: January 16, 2024Assignee: Cisco Technology, Inc.Inventors: Jay K. Johnston, Jerome Henry, David C.

Patent number: 11089503Abstract: Techniques for automated network adjustment are provided. A first data rate currently supported by a first access point is determined, and a second data rate is identified to be evaluated. A first sensor device of a plurality of sensor devices is identified, where a signal strength between the first sensor device and the first access point exceeds a predefined threshold. A first packet error rate is determined for communications between the first sensor device and the first access point using the first data rate, and a second packet error rate is determined for communications between the first sensor device and the first access point using the second data rate. Upon determining that the second packet error rate is lower than the first packet error rate, the first access point is automatically reconfigured to use the second data rate.Type: GrantFiled: January 8, 2020Date of Patent: August 10, 2021Assignee: Cisco Technology, Inc.Inventors: John M.
