Do you see the gray cable which goes around the battery. It is soldered to the mainboard on the battery side on the left of the metal bar and to the wifi antenna on the other side of the battery. Both places have to be checked if the soldering is failure free. The antenna can be checked too, there is a metall mesh glued to it which connects to the metal displayframe. I don't know if this is necessary but on my device and on urbies pic this connections is existing.
