It appears that not all hardware/firmware implementations support group key deletion correctly, which can lead to connection hangs and deauthentication following GTK rekeying (delete and install). To avoid this issue, instead of attempting to delete the key using the special WMI_CIPHER_NONE value, we now replace the key with an invalid (random) value. This behavior has been observed with WCN39xx chipsets.
