Anyone having issues with the WiFi connecting?  1. - It will join a network, but when the phone locks and has been off for awhile it won't reconnect.  2. - If I go home or work it won't automatically connect.  It says "Obtaining IP Address".  The only way it will reconnect is with a reboot, which I have to do several times a day.  I have toggled the settings for "Keep Wi-Fi on during sleep" between "Always" and "Only when plugged in" and also toggled the "Wi-Fi optimization" on and off with no success.  I did notice that the MAC address displays Unavailable in both the WiFi settings and the about phone.  I am on the CM11 20131201 Alltel build.
Edit:
This doesn't happen every time, but most of the time.
