(transaltion)I installed the lineageos 14.1 on my Samsung Galaxy tab E sm-t113-nu device with Android 7.1.2. Everything was going well, I looked for my WiFi, I put the password, the problem turns out that it does not connect, it says establishing connection and it starts and says "saved" after a while, it says disabled I have restarted the erased device and put the password back and nothing I have sought help from a forum with my problem and it is not. I know that for this model they don't have much help
