From eb6002526b1c5cb3e7f9e42004ba395f5d57beaf Mon Sep 17 00:00:00 2001 From: Abhijeet Kolekar Date: Wed, 13 Jan 2010 13:23:14 -0800 Subject: cfg80211: fix channel setting for wext commit 5f6120335c701ba07d5151206071f4d6ccaa684f upstream. Patch fixes the bug at http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2139 Currently we cannot set the channel using wext extension if we have already associated and disconnected. As cfg80211_mgd_wext_siwfreq will not switch the channel if ssid is set. This fixes it by clearing the ssid. Following is the sequence which it tries to fix. modprobe iwlagn iwconfig wlan0 essid "" ifconfig wlan0 down iwconfig wlan0 chan X wext is marked as deprecate.If we use nl80211 we can easily play with setting the channel.
