There is some bars (which indicates the strength of the wireless), right click there is disconnect option, so ... sometimes it didn't plug in, while sometimes it plugged in, not worked (I felt the patience and retry plug in can get rewards at that situation) , so I enabled the wireless again.

Also, review the messages with "tail -f /var/log/syslog" and wow, after disconnect the wireless, unplug the cable and replug the cable, interesting scenario in syslog, disconnected the wireless first and then plug in worked. but if it's already plugged in. disconnected the wireless, it's not so sensitive. How do the laptop examine whether there is cable connected or not?
