It's busted. It's *known* busted. You transmit packets for more than a minute or so using WEP, you may as well not bother with crypto at all. Yes, it's really that busted. 2) You're much better off spending the $15 to get a wireless card that actually has hardware WPA2 support on it. The devices are cheap, there's no reason to inflict pain on yourself. I'd not be at all surprised if a card that doesn't have crypto support isn't *also* lacking other hardware support for WPA/WPA2 So while it may well be *possible* to do it in software, I'd have to rank it as one of the more masochistic ideas I've heard in a long time. --==_Exmh_1379079132_1704P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iQIVAwUBUjMT3AdmEQWDXROgAQJNVg//S52NXny5ysNI2ZtcZ8/OgBYWGssDO1Vi 33LpAlArd8Y3WzVV23wtphYQQ8hLzDnQtv/WFEKLphxA18UqWaBxH47zGr9ZKfes UuuG62Z5fbdorRM6yFXZhMJE4mZeUEUwjmDRsCaeCQZ8EWyk/dC93T56iTTC/FVQ 57vj4NRhM47aCnSbnr3XxwhfhPkKrP01CxNBboAlu1ljvLK4Rkz0wZ2k7GFpFyzr gzXhjd2UiaVRApTZvkc3F8zeIipDufMVb4z2OKWTFmVRI/2erYEkioMNFb4yFnme 0LoxsjafXUghM1Kpuon5UWzpJ0DLRMS1ZnWHlBQjo0B4d2RpIHAxfzsD2way0M93 Q4uymaAPcONP7uRwKQTM7c6rRSYsxX/JhaedioZ72ftlRNXayhc52R1NWw/2WHyG YgiIkE1S86N1ZWldWRq6J4n+nCXYxGAMHe/H6/DVKhqLE0TC9a2p5EuZXr+Sv/7b 8ErPAG6IlxKfdPlhJnO1GNkyVPrfne5dwKQ9iGDfte4m8a5l0TVkfSNVmM7kTewK 5czum4xfZ2z4xMar/GLnBNYWzh6M6G/hLmUn+l/S/vT7GWgeJHzvnRN1zoa8NmK0 Cb+vZYLXCkGtyl1nVL1nTiO/shuYbrb4cfImYuqXGDmQIjbgC8XgGtlAmb1Zv1B2 1d4z4FyfXM8= =ywzV -----END PGP SIGNATURE----- --==_Exmh_1379079132_1704P--
