Ok now I'm starting to get upset. I did some research. Previous versions didn't like having both wired and WiFi connected. So I made sure wired network was not connected. The 1900AC is useless in WiFi as it keeps disconnecting. I have to disable Wifi and reenable it to re-establish the connection all the freakin time.
This is the 3rd post on this matter with no response what so ever.
Buy another box from another brand. I was hoping 5.1 would make this box more stable but no success so far. I have a 582 that I love, no issue with it but just not as much CPU and Mem as I wished. I went for a 1800. The 1800 running Android 4.4 is the golden years of the MyGica. Flawless. Then I wanted to have another room covered. I went for a 1900AC. That thing is a disaster out of the box. Not reliable what so ever. The only setup I managed to have running relatively stable after countless factory resets is Wired with latest patches. Now I need it to be wireless. I was hoping on 5.1 with no success. The wifi issue makes it useless again and no suggestion or help on the support.
