So, as long as you set up=20 wpa_supplicant to use proto=3DRSN with pairwise=3DCCMP and group=3DCCMP you= will=20 always connect with the AES encryption standard. NOTE: It is not necessary to specify CCMP because it is used by default as= =20 the first option, but if you don't specify it and the AP uses WPA/TKIP only= ,=20 then instead of the connection failing wpa_supplicant will switch from CCMP= to=20 TKIP. I'm stating the obvious here, but if having a wireless connection is= =20 more important than *always* using AES, then of course you do not need to=20 specify CCMP. =2D-=20 Regards, Mick --nextPart1560344.BP89k4pu3N Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) iEYEABECAAYFAk6imDEACgkQVTDTR3kpaLY8dgCeO2DdpPyun6wZnPEnXqXWzyXu eswAoN/d2YGmF7/9w+ZwDK6B9VFX0YGW =AyDR -----END PGP SIGNATURE----- --nextPart1560344.BP89k4pu3N--
