Network Apparatus Wireless Connection Verification After Settings Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless network management, changing settings on a device can lead to connection loss with the user's terminal, making it difficult to confirm the device's operational status, especially in wireless LAN systems conforming to IEEE 802.11 standards, where changes in communication channels or SSID can disrupt communication.
Innovation Solution
A network apparatus with a wireless communication unit, connection control unit, storage units for connection data, and test units that record and test new connection settings, allowing the device to temporarily disconnect and reconnect to verify operational status and report results to the user's terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connection settings are changed on the to-be-managed device, then the device can operate with new communication parameters, but the connection between the user's terminal and the to-be-managed device will be cut
Solution Approach 1:
The system performs a test connection using the changed settings before actually applying them. The connection control unit establishes a test connection with the to-be-managed device using the modified settings, and only if this test succeeds does the system switch to using the new settings permanently. This preliminary testing action prevents connection loss by verifying settings work correctly before full adoption.
2Loss of information
If the user's terminal cannot access the to-be-managed device after settings change, then connection is lost, but the user needs to confirm whether the device is operating properly
Solution Approach 1:
The system implements a feedback mechanism where the to-be-managed device automatically sends operational status information to the user's terminal even when direct connection is interrupted due to settings changes. The test connection unit verifies device operation, and the system transmits this verification feedback to the user's terminal, allowing the user to confirm proper operation without maintaining continuous direct access.
3Extent of automation
If settings are changed remotely via network, then centralized management is achieved, but the connection may be cut due to setting problems
Solution Approach 1:
Before remotely applying settings changes to the to-be-managed device, the system first performs a test connection using the proposed settings. The connection control unit establishes a test connection with the to-be-managed device using the changed settings, and only if this test succeeds does the system switch to using the new settings permanently. This preliminary verification maintains connection reliability while preserving remote management automation.
Solution Approach 2:
The system prepares a backup connection using the original settings before applying new settings remotely. If the new settings cause connection failure, the system can revert to the original settings, cushioning against the harmful effect of connection loss. This is achieved by maintaining knowledge of both old and new settings and being able to switch between them based on connection status.
