I think there are pre-wifi HT IEs too in some vendor IE, might be one of these. https://mentor.ieee.org/802.11/documents?x_dcn=3D31&x_year=3D2009 is useful too (at least for 2009, for next year somebody will have to find the DCN again) > However, as I said before, I am quite happy now since the provided > information by iw are now the same as I get with iwlist.

I'll wait a bit, maybe somebody feels inspired by this to provide HT parsing. johannes --=-KqSzXZM8zp1+y+/iNcJZ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJJ/yd7AAoJEKVg1VMiehFYJ5IP/2fT1eek5I1OnEWTCG+HVQYb pNogO9ziVDtiaCTuhlmjPmX43WGsXkFIOFleX7KRTbye11dnSHn55F2qNEiQmQja HXoPpEHrrBCeOdvOOeUrbcYS7KMdGIrCEtIVMTyKul3FnbVoj74U9PtLS5z/CWJz U1dyBJSptrJgMaLM6Xkcy5g48h7ZV8BOSQMnskhevG90cENW3bWKMOpIPfF6Jejd /CcpN85tRqK/BZK4LaKy+0kIrG/R0Xxcm5hfsg7ySpHk6r6JJBvuo8DdMikHyqgm ucM8mGiZvGJ0UKHW76F29y65x4S/uX6srRXDPLSodfti/EejAgUFxLxtv6fpvky7 v3kLBWnb13QYS5luaJh4R/d9Q1WQ5wuGoz2lAutx0ZjAZ8GvjP7ypxcQMuICNNtE jwoR26y62Pp8ZYNZeL2aJ0ftiyjUxdPvLcxpnRo6ngB0JwdVY4mfKi9ArOXAOCia SPr8vJMGR2Y+vlwrpOTA4tyM4XwJV3aZ5uV0kqA7gsO1cN2YHPngw9d6XAhjazTf cGbA82tOVwpAK457dcgAcCDR/0FHr+UCbVNRAm4Q7+jQLIpycHbu/f8PHWHSh0XQ 3HEqaO/6YUlX3lbtWZ9XUaz1cWHiy05ALWSSiqzl4oVR/7tC62ODx2yT7JkU9fma 4Sjjq1pOAgdXhtqPjGaM =dQzn -----END PGP SIGNATURE----- --=-KqSzXZM8zp1+y+/iNcJZ--
