My Wifi was working great and then I read some guy was having some luck with Juice Defender saving battery juice. My battery sucks so I thought I would try it. Ever since the JD install, i have not been able to get Wifi to work... I get a message that says "unable to scan for networks" when I turn on the Wifi. Uninstalled the JD and that doesn't make a difference. Still get the message and no Wifi. What am I missing? Did JD turn something off that needs turned back on? Thanks in advance.
