Getting Maximum Wifi performance while on batteries -- Thinkpad General

Question

I bought a w520 last week.  It's a lovely machine, but unfortunately it's frequently had terrible wireless download speeds straight out of the box.  Wired, it was 11+ Mbps.  Wireless, I've hit a high of 6+ and a low of .2.  It is extremely uncommon for me to get between .2 and .75 Mbps.   Is there anything that can be done to increase the speed?

 

Answer

 

This can easily be rectified by going to Windows "Power Option" (Not Lenovo Power Manager) and changing the setting for the wireless. In order to do this please follow the instructions below.

 

  • Go to the "Control Panel" and open the "Power Options". A new window should appear. (Please see illustration below.
