Packet lost problem about connecting to master-board using wifi

Software
1

Hello everyone.
According to the readme of master-board-sdk,master-board support both Ethernet connection and wifi connection.
I set the wifi to monitor mode,and run the example,the packet lost is very high,output log as below:

    |     accelerometer    |       gyroscope      |       attitude       |  linear acceleration |
IMU |   0.00   0.00   0.00 |   0.00   0.00   0.00 |   0.00   0.00   0.00 |   0.00   0.00   0.00 |

Motor driver errors: 14396 | 14396 | 14396 | 14396 | 14396 | 14396 |

The led of master-board turn blue in a short time and then turn red again.

Does a better wifi hardware can sovle this problem,or some setting need to be done for master-board?

Thanks very much！
