i have two rca tablets but one is having authentication problem . im unsure as to what type of usb cable will help to transfer information or do i have to get closer to the router to accomplish this. also one tablet will not accept my password which works on my second tablet..also i did a factory reset so my problem rca tablet is blank and i cannot even connect to the internet. it seems that every action i take only worsens the problem,. im asking for any ways to resolve this problem..thanx
