It's only my Moto X and only my home WiFi. It only happens once or twice a week, but it is annoying to have to reboot.
Mostly unrelated, but my Bluetooth icon doesn't always change state. I've noticed that sometimes even hours after getting out of my car the Bluetooth icon is white instead of dim gray like it should be when not connected. That doesn't seem to have any bearing on the ability to connect, just something I've noticed. Usually toggling BT off and on again fixes the issue.
Phone is a rooted 4.4 Verizon Moto Maker edition. I do have SnapDragon Battery Guru installed but I never set anything up to save power. There is a setting in stock WiFi settings about consuming less power on WiFi, but that would seemingly impact all networks, not just home, and it would only be in play once I am connected to the network, not before.
I do use Tasker to enable my WiFi when I get near home (based on cell towers when and I'm NOT connected to BT in my car), so WiFi typically shuts off when I leave home, turns on when I get to work (based on calendar events), turns off when work is done (calendar) and then turns on when I exit my car (BT disconnects and I'm connected to one of a few nearby towers). Only seems to happen when I get home from work, so it could be something in Tasker not properly enabling WiFi? If I notice it again I will try to connect to another different network before rebooting, if there any unsecured networks nearby at the time.
Thanks for any advice.
