    • 20 MHz SISO
    • 40 MHz SISO

    Software Limitations

    • AP/P2P/Mesh SISO40 in 2.4GHz is not supported, due to missing components in the implementation required to meet specification requirements.
    • Multi Role concurrent operation supported modes:
      • Station + AP / P2P GO / P2P Client / Mesh
      • AP + AP (See MBSSID feature limitations above)
      • AP + P2P GO (Single Channel) / P2P Client (Multi Channel)
    • Wake on Wlan feature might required custom patches, and ECO on some platforms.

    Known Issues

    Bug ID Description
    [WILINK8_SW_DEV-655] Mesh on demand: Mesh and STA connection and ping pass although the RSSI above the threshold for AP connection.
    [WILINK8_SW_DEV-555] Co-Ex: Bluetopia: Any Role: 5G: Lower WLAN throughput while using Bluetopia profile such as FTP and A2DP.
    [WILINK8_SW_DEV-66] mesh:iw: some parameters displayed using ‘station dump’ are not updated
    [WILINK8_SW_DEV-98] Multi-Role: Connection to APUT during traffic in secured SUT network takes longer than expected (seconds)
    [WILINK8_SW_DEV-580] Firmware recovery might occur after long time (>12 Hours) while WLAN running UDP/TCP traffic
    [WILINK8_SW_DEV-581] Robustness : Firmware recovery might occur while running extensive connection tests and traffic
    [WILINK8_SW_DEV-451] Stability: Co-Ex MR: STA-AP-BT: STA -TCP Rx, AP-TCP Tx, WPA2; BT-eSCO , BT HF might stop after long hours, while WLAN traffic continue
    [WILINK8_SW_DEV-222] MR mBSSID: Remote Stations might disconnect, from time-to-time (>10 hours), during TCP Rx
    [WILINK8_SW_DEV-533] STA: TCP Bidir: Throughput delta between RX and TX might vary in different modes
    [WILINK8_SW_DEV-373] SUT might disconnect while running traffic during intensive BT inquiry with 10 seconds interval
    [WILINK8_SW_DEV-240] AP IOP: extSTA disconnects after an inactivity timeout, when any activity is initiated from the STA, while is connected idle
    [WILINK8_SW_DEV-227] MR AP+P2P: Variable P2P connection success rate during APUT’s high consistent traffic
