         0x72, 0x72, 0x72, 0x72, 0x72, 0x72, //All "F" SSID
                        0x01, //ID meaning Supported rates
         0x08, //length
         0x82, 0x84, 0x8b, 0x96, 0x24, 0x30, 0x48, 0x6c, //Supported rates
         0x03, //Channel Option
         0x01, //Channel Len 1
                /*56*/  0x01, //Channel
   };

Anyone know why my Timestamp is being overwritten? I assume SendPacketFreedom does this on 0x80, 0x00 Management packets?

*Bump* Anyone?

Do you capture a wrong packet?
The packet in your picture seems not corresponding to your source code.
In your code, the SSID is

Code: Select all

0x72, 0x72, 0x72, 0x72, 0x72, 0x72

.
But in your picture, the SSID is "testing".
