Virtual Access Point Auto-Reconnection for Wireless Credential Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks require manual reconfiguration of client devices when network credentials such as SSID or password are changed, leading to inconvenience in maintaining network security and connectivity.
Innovation Solution
Implementing a system with multiple virtual access points (SVAP, NVAP, UVAP) managed by a smart network host device that automatically authenticates and reconnects client devices using stored credentials, allowing seamless reconnection even when network credentials are updated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual reconfiguration is used for each client device when network credentials change, then network security is maintained, but user convenience and time consumption deteriorate
Solution Approach 1:
The system segments the reconfiguration task by introducing a network administrator device that separates the credential management function from individual client devices. The administrator device can push credential updates to multiple client devices simultaneously, eliminating the need for manual reconfiguration of each device while maintaining security through controlled credential distribution
Solution Approach 2:
The system creates and distributes copies of network credentials from the administrator device to multiple client devices. When credentials need to be updated, the administrator device generates new credential copies and pushes them to all authorized client devices automatically, ensuring security through centralized control while improving convenience through automated distribution
2Manufacturing precision
If manual reconfiguration of each client device is performed when credentials change, then accurate credential updates are ensured, but time consumption and operational complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring the administrator device with the authority and capability to push credential updates to multiple client devices. This preliminary setup enables rapid credential distribution when changes are needed, ensuring accurate updates are pushed simultaneously to all devices without requiring time-consuming manual reconfiguration of each device individually
Solution Approach 2:
The system implements feedback mechanisms where the administrator device tracks which client devices have successfully received and applied credential updates. This feedback loop ensures accurate credential propagation across the network while minimizing reconfiguration time by identifying and notifying devices that need updates, rather than manually configuring each device in sequence

AI summary
A host device for a wireless network may be configured to implement at least two virtual access points for connecting client devices to the wireless network. A user virtual access point enables a client device to connect to the wireless network and transmit network traffic to other devices connected to the wireless network. In addition, a setup virtual access point provides an additional access point to connect to the wireless network when network credentials for the user virtual access point, such as a service set identifier (SSID) or a password, are changed by a user. When a client device cannot find the user virtual access point based on a stored SSID or password, the client device may be configured to automatically reconnect to the setup virtual access point to request a new SSID and network credentials for the user virtual access point.
