We can consider that the wifi issue is resolved in iode OS version 6.9-20251116.
An OTA update with the version is getting pushed tomorrow to all devices.
There were many firsts for iode with the brax3 - first time working with mediatek chip, first time not starting with a LOS port, etc. etc. But they pulled it off.
Thank you all who helped resolve the issue whether through development, providing feedback, testing new builds, or simply nudging
