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.
