Information Processing Apparatus Router Communication Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication instability between an information processing apparatus and an image forming apparatus via a router due to factors such as radio frequency interference and unsupported frequency bands, leading to unsuccessful wireless connections.
Innovation Solution
Implementing a control method in the information processing apparatus to determine communication feasibility via the router, and if unsuccessful, display messages to disable band steering, set distinct SSIDs for different frequency bands, or enable a different frequency band supported by the image forming apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If band steering function is enabled in the router to allocate optimum frequency bands to slave devices, then network performance is maximized, but communication stability deteriorates due to signal strength differences and radio frequency interference between devices
Solution Approach 1:
The information processing apparatus performs preliminary detection of communication feasibility between the image forming apparatus and router before establishing the wireless connection. When communication failure is detected, the system proactively displays troubleshooting messages to the user, preventing the establishment of an unstable connection rather than allowing it to fail during operation.
Solution Approach 2:
The system implements feedback by detecting communication status and providing user guidance based on the detected issues. When communication failure is detected, the apparatus displays specific messages (band steering disable, SSID differentiation, or frequency band enablement) that provide feedback to the user on how to resolve the specific communication problem.
2Device complexity
If different slave devices use the same radio channel in a frequency band, then device simplicity is maintained, but radio frequency interference occurs causing communication instability
Solution Approach 1:
The system performs preliminary communication feasibility detection before establishing the wireless connection. This preliminary action identifies potential radio frequency interference issues before they manifest as communication failures, allowing the system to proactively guide users through troubleshooting steps.
3Device complexity
If a printer main body supports only one frequency band, then device simplicity is maintained, but communication capability deteriorates when router prohibits communication between different frequency bands
Solution Approach 1:
The system provides feedback to the user by displaying specific troubleshooting messages when communication failure is detected. One of the messages guides users to enable the frequency band in the router that corresponds to the single frequency band supported by the image forming apparatus, helping users adapt the router settings to match the limited capabilities of simpler devices.

AI summary
An information processing apparatus determines whether it is possible to communicate with an image forming apparatus via a router. The information processing apparatus executes, based on it being determined that it is not possible to communicate with the image forming apparatus via the router, predetermined processing for displaying at least one message among (i) a message for disabling a band steering function in the router, (ii) a message for setting each SSID of a plurality of access points in which used frequency bands are different and which are enabled by the router to a different character string and, (iii) a message for enabling, in a case where the image forming apparatus does not support a first frequency band, a second frequency band different from the first frequency band in the router.
