I found a very weird effect on my Lenovo X220.

when I am on battery power and boot the wlan connect is like instantly!

when i am on AC power and boot, the WLAN connect (to the same home wifi) does take up to 30 seconds!! also a manual disconnect and reconnect takes the same time.

i have no idea how to change and explain that. i am too new to linux to know which config files and log files to check

ANY hint is much appreciated. found no advice anywhere on the net.
