Has anybody > tested RTS/CTS in detail? for that i think it goes beyond my abilities... i forgot to say about the AP, i think it's not g wifi, it's MIMO. perhaps it could change something. and for information, the second computer i use to do the tests is also a 3945ABG intel wireless, but installed with ubuntu and iwl3945 too (but the default installation), with a 2.6.24 kernel. the difference with me, except the computer itself, is debian, kernel 2.6.26 compiled by myself, and before i used ipw3945, but remove it completely thanks cedric -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
