wifi is gone after reboot

[tina]

No, it did't help.

I also get this error messsage:
"Error for wireless request "Set Encode" (8B2A) :
invalid argument "My_KEY" if I run 'ifup wlan0' without running 'sudo iwconfig wlan0 key s: MY_KEY' first.

After I run the key command, with the same key_name that error message complained about, 'ifup' works.

Sometimes after the key command the error message still appears when running 'ifup', but the command works nevertheless.

Sorry, I did not notice the last line about waiting for the red light to turn off. I am doing it now again(sync and halt).
Waiting for for almost 30min now. Should it take that long?
