From eef6caf8a916f32f8d9b2a02d4fa7674736c00ac Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Mon, 2 Jul 2007 22:36:38 -0700 Subject: [MAC80211]: Set low initial rate in rc80211_simple The initial rate for STA's using rc80211_simple is set to the last rate in the rate table. For situations for which the signal is weak, the rate may be too high for authentication and association. Although the rc80211_simple module will adjust the speed, the response may not be fast enough for a successful connection. This modification sets the initial rate to the lowest supported value.
