I used 802.11b mode.
I changed the BasicRate with registry key "dot11BasicRateMaskB".
Then, I was able to confirm BasicRate in ProbeRequest had changed.
But, when connecting with AP, the BasicRate in AssociationRequest
is different from the value that I specified in the registry key.
It is the same value of AP's BasicRate in BEACON/ProbeResponse.
Is not the value of registry key "dot11BasicRateMaskB" reflected in AssociationRequest?
