Lg Aristo. Problem started yesterday. I have taken the battery out, powered the phone off, and re started the router. I cannot sign in to my wifi account. It will not accept my username and password. Meanwhile, my laptop is working. It is only my phone. Other phones in the house are working. My phone is not working on the road either.I took it 3 hours away and could not use the gps by wifi, had to use mobile data.
