WNA1100 doesn't awaken Win7 PC

WNA1100 on a Lenovo PC running Win7,  driver has latest update;  network signal has all 5 bars lit up.

When I awaken the PC (by moving mouse) after it sleeps,  the computer wakes up but the WNA1100 does not wake up, nor does the blue light start flashing, and a message says" cannot connect to Internet."  

I can't find a setting to automatically awaken the WNA1100 when computer wakes up.  I usually awaken the WNA1100 by removing the WNA1100 from its USB socket and immediately putting it back in the socket;  then blue light starts flashing and it connects to WiFi network and Internet just fine.   How to fix ?
