CSI data collection leaked

[yjxb1]

The following is the composition of the experimental equipment:

1. Router
2. Two Raspberry Pis, one for pinging data to the router and the other for grabbing CSI data
   But now I have a problem collecting CSI data. I used Raspberry Pi to ping the router for 100 packets, but the collected packets were less than 100, and the number is not fixed. Sometimes I can catch 90 packets. , sometimes I can only catch 40 or 50.
   Can you guys help me answer this question?

Very late response but it likely has something to do with the signal strength, or RSSI. Try to move the devices closer
