Wifi is crappy in C2D6 also. You’ll get good transfer rates IF you line of sight to router, if not transfer rates will significantly drop. In a same place other wifi device gets about ~5 Mbs and Teclast x98 plus2 C2D6 gets ~0.8 Mbs.
It indeed did work. Took about one night to update.
Annoyingly reboot doesn’t work if charging cable is connected, device gets stuck to charging symbol.
