With the ubiquity of Wi-Fi, it has become an essential infrastructure for modern life. Yet compatibility challenges remain one of the most critical risks before product launch. A single compatibility flaw could trigger waves of product returns in the market.
Allion assisted a home appliance manufacturer by conducting customized verification for its soon-to-launch thermostat. The tests uncovered connection issues caused by the new WPA3 standard. By identifying and resolving these issues before launch, the manufacturer avoided customer complaints and product returns, while saving significant time and costs.
From Wi-Fi 6 MU-MIMO to Wi-Fi 7 MLO: New Technologies Bring New Compatibility Challenges
Devices fail to connect
Many users encounter issues where smart home devices, surveillance cameras, or IoT products cannot properly connect to home Wi-Fi. This often occurs when devices do not support new Wi-Fi 7 features (such as MLO—Multi-Link Operation) or cannot correctly handle updated security protocols (like WPA2/WPA3 mixed mode or the new WPA3 OWE).
Unstable or frequent disconnections
Even when a connection is established, frequent drops or high latency may occur. This is typically due to partial incompatibility between device wireless chipsets and routers. For example, some devices cannot reliably support Wi-Fi 6 features like OFDMA or MU-MIMO, or fail to reconnect when routers automatically switch channels.
Inability to use specific features
Some advanced features, such as voice activation on smart speakers, wireless video streaming, or app-based remote control, may fail in certain Wi-Fi environments. This is often due to router differences in QoS (Quality of Service), bandwidth management, or IPv6 support, causing functionality breakdowns.
Exposing Hidden Risks: From Interoperability to Real-World Scenarios
1. Interoperability testing across brands and generations
Allion conducts strict interoperability testing with mainstream router brands (e.g., TP-Link, ASUS, Netgear). Cross-testing simulates real-world use cases, helping manufacturers identify risks early in development and prevent post-launch compatibility issues.

2. Stability and performance testing
Allion provides long-duration stability tests (e.g., continuous 24-hour operation), multi-device concurrent connection testing, and interference simulations (Bluetooth, microwave ovens, other Wi-Fi signals). These ensure products maintain performance in varied environments.
3. Real-world scenario simulation
To reflect real usage, Allion incorporates diverse scenarios (homes, apartments, offices) and conditions such as signal attenuation by distance, roaming in motion, high-interference environments, and heavy data loads. This ensures comprehensive validation of product performance and reliability.
WPA3 Connection Issues Nearly Derailed Launch – Allion Helped the Thermostat Manufacturer Avoid Disaster
Allion recently assisted a home appliance company by testing the compatibility of its new thermostat with commercially available routers. Based on customer needs, Allion tailored test items to match the thermostat’s expected usage and selected routers aligned with target sales regions.
During testing, major issues quickly surfaced:
- When connecting with WPA3 (SAE) security mode, the thermostat displayed password errors and failed to connect.
- When using WPA3 Enhanced Open (OWE), the device was unable to connect at all.
These issues stemmed from new WPA3 requirements that had been overlooked in product design.
Fortunately, Allion identified these problems before shipment, enabling fast fixes and preventing customer complaints or product returns—saving the client significant time and costs.
