I am running RHEL6 on my laptop. The wireless adapter configuration file ifcfg-wlan0 didn't come by default under /etc/sysconfig/network-scripts. So I created it myself. The problem is, whatever changes I made to that file, it just won't make a difference. The wireless connection only drops immediately after I issue the command /etc/init.d/network restart, but will resume working fine after I manually choose a wireless network, and the changes I made won't apply(see the picture bellow). How could this happen?
