Succ Reass Packets The packets successfully reassembled.
Unsucc Reass Packets The packets unsuccessfully reassembled.

receive it and transmitted the packet again.
Undecryptable Pkts The total data packets that could not be decrypted.
Rcv CRC Errors The Packets received that contained CRC (Cyclic
Redundancy Check) errors. An MU transmitted a
corrupt data packet and failed to pass the CRC
verification. Ensure that any acknowledgment of the
data packet contains the correct CRC word.
An incorrect CRC causes the AP to discard the
data packet.
Rcv ICV Errors The Packets received containing ICV (Identity Check
Value) errors. An MU transmitted a corrupt data
packet and failed to pass the ICV verification. The
calculated ICV value does not match with the ICV
value in the received packet.
