[LG Optimus L9 P760, P765, P768, P769] saturnianalien:
I've noticed that there are some issues with WiFi and WiFi calling going to sleep. So I took a look at dmesg and am noticing CFG80211-ERROR everywhere. Why would this be? I haven't done anything to my phone, except root it by the lelus method. But even before root, the WiFi would act up. Here's some CFG80211-ERROR's in my dmesg.
