At the TAP mode, LE-580FX Window is forced to handle many processes. For example, it converts every 500 capturedpackets to a file. Under the communication of high frequency, there is a possibility that LE-580FX Window cannot catch up the process of receiving packets from LE-580FX. Thus, it may cause the loss of packet capturing. In this case, Wireshark has the better performance of packet capturing.
