Decrypt it and find the key.

Our operatives were able to decrypt packet #18 in the capture file.

The decrypted data is 18060a0700421a63343a636f6e74726f6c345f73723235303a43342d53523235300400420830332e30312e3534050020040600213c00 or (printable text only)

If you aren't getting the correct values, make sure your keys are correct, and that they are entered correctly. Keep in mind bits sometimes flip when transmitting signals wirelessly.
