keeps knocking me of wifi, i can't even keep it running long enough to remove my personal data to return it. Sometimes when I go to re-establish a wifi link, it says it is connected! But, it won't pull up anything. I have fiddled with it enough that I'm sick of it. Had my old HP fixed for $40 and it is up and going with NO internet access issues.  I know it's refurbished, but when a little old  man shop for computer repair in a one-horse town cane fix my old one in 15 minutes, why can't these expert repairmen give me something that works!!
