My UBox Gen2 AC/DC adapter was broken because of lightning strike. Replaced it with the same specifications, 5V, 1.5A. Then started having problems. The Wi-Fi signal often dropped to level 2 or 1, and got high memory usage at the home screen or when I was opening UBTV. Also often got error message, saying no internet connection when trying to open UBTV. I only installed 2 main apps: UBTV and Kodi. Please help. Thank you.
