For the last few days, the wi-fi on my HTC DNA is constantly turning on and off, without my doing anything; I cannot get it to stop doing so either. I have tried stopping it in the wi-fi menu, settings, drop-down settings, and even turning on airplane mode. Nothing works (outside of keeping the phone off, but that's not really a solution). Since it is constantly turning on & off, this is draining my battery, tanking a full charge in a day (my normal use drains a full charge in about 2.5 days).
I last updated the phone in May (upgrading to kernel 4.4.2). If necessary, I can provide more information.
