Not sure exactly where you are on this as there was no previous indication you had a problem in this topic ??
And on the wifi, I hope you don’t mean it’s stable as it’s totally unavailable 
UPDATED:
AH! found you
And again
But even on that post you don’t detail what you did to recover and get the phone working . . . Is that on another post? If so please provide a link or be so kind as to provide the detail on the previous post.
