Re: Continuously dropping connection.

Can't see your pic. Since you are a new poster, it needs to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting it at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to it here.

Or copy all of the text of the status page and paste it into the body of your next post here.
