Go to Settings - Wifi (tap on wifi, not the toggle on/off) - then you'll see a list of wifi networks your phone remembered. Long press your home network, and you'll see the option to forget the network.Same problem is happening on my Moto X. Since about 1 week my phone keeps forgetting my home wifi password. I tried resetting / repowering phone + modem, no luck. Don't understand how / where to "forget" the wifi connection either. Appreciate if anyone has tips.
I'm also on AT&T 4.4.2. I haven't had the issue. Not sure where to start. Maybe, do you have any apps installed that manages your wifi? Perhaps some automation like Tasker? I don't know enough to suggest anything more.I've noticed that my X sometimes forgets my wifi passwords and I have to re-enter them. Currently on ATT version 4.2. Has anyone else had this issue?
