Many laptop users struggle with assessing their WiFi connection quality quickly and passively. Currently, they must actively run speed tests or interpret vague connection bars, which is inconvenient during important tasks like video calls or online gaming. This creates unnecessary friction in daily digital workflows where reliable connectivity is crucial.

A visual WiFi quality indicator

One solution could involve transforming existing laptop lighting systems into real-time connection monitors. Through keyboard backlights or screen-edge lighting, different colors could represent various connection states - for example, green for excellent speeds (>50Mbps), blue for good (10-50Mbps), yellow for fair (5-10Mbps), and red for poor connections (<5Mbps). The system would continuously monitor key metrics like:

• Download/upload speeds
• Latency fluctuations
• Packet loss rates

For devices without RGB lighting, alternative display methods could include subtle screen-edge glows or status bar indicators. The implementation could work through a lightweight background application that automatically adjusts lighting via existing manufacturer APIs, requiring no additional hardware for most modern laptops.

Matching user needs with technical possibilities

This approach would particularly benefit remote workers needing reliable calls, gamers sensitive to latency, and travelers using various WiFi networks. The visual nature provides instant, intuitive feedback without interrupting workflows. From a technical perspective, various implementation paths could be explored:

1. Starting with an app controlling RGB keyboards on Windows laptops
2. Expanding to macOS support where hardware allows
3. Eventually partnering with manufacturers for deeper system integration

The system could maintain minimal resource usage by optimizing test frequency and prioritizing essential metrics during normal operation. For users with customized lighting setups, temporary overrides or dedicated lighting zones could preserve both aesthetic preferences and functionality.

Differentiation from existing solutions

Unlike manual speed tests or complex network monitoring tools, this approach offers passive, glanceable feedback where users need it most - directly on their working device. While some routers have basic connection lights, they don't provide device-specific or speed-related information. The closest existing solutions either require active engagement (like running speed tests) or cater to IT professionals with overly complex interfaces.

This suggestion effectively bridges the gap between technical network information and everyday usability, potentially becoming as fundamental as battery indicators are today.
