High Level Architecture
The internal functional entities of the OneWifi process are as shown in the above diagram. OneWifi software architecture is essentially a multi-threaded software architecture, the three main threads are
- Core thread: this thread is the fundamental engine of the process that is responsible for all configuration of WiFi parameters, command/control/status response and WiFi state indications. The core thread is also responsible for steering related activities.
- DML thread: this thread handles the TR-181 set/get handlers.
- Apps thread: this thread is responsible for supporting all WiFi related application/features such as harvester, motion sensing, blaster, single client measurements etc.

Test Procedure
Pre-requisites
- 802.11be enabled on all bands — 2.4 GHz, 5 GHz, and 6 GHz radios must each have 11be enabled (and be enabled).
- Same SSID on all VAPs participating in the MLO group.
- Same password on all VAPs participating in the MLO group.
- Security mode:
- 2.4 GHz & 5 GHz → WPA3-Personal-Transition, WPA3-Personal-Compatibility or WPA3-Personal
- 6 GHz → WPA3-Personal
- All participating VAPs enabled (one link per radio; STA/mesh VAPs excluded).
| Mismatched SSID, password, or an incompatible security mode causes that band's link to be silently excluded from the MLD group. |

Enable 3-link MLO for private VAPs via TR-181 DM
