Unstable Internet Connection
An unstable Internet connection is the most common cause of problems that occur with large file downloads. To successfully download files from any Website or FTP site, you must have a stable connection to the Internet.

If when downloading a PDF, one or more of the following occurs:

• Nothing happens when you try to connect or download.
• An error message appears when you try to connect or download.
• A file transfer pauses intermittently while downloading.
• A file stops downloading before the download is complete.
• An error message appears when you try to run or open a downloaded file.
• Your computer unexpectedly disconnects from the Internet.

Do one or more of the following:

Solution 1
Contact your local telephone company or your cellular service provider for assistance with checking line clarity or with temporarily disabling telephone service features that may interfere with your Internet connection. Such as Call Waiting.

Solution 2
Contact your Internet service provider to verify your connection to the Internet is stable.

Solution 3
If you are certain your Internet connection is stable and you still encounter problems when downloading, see "Downloading Help Documents" on the Adobe Web site for additional solutions.

You are more likely to have a problem with your Internet connection if one or more of the following are true:

• Your rate of transfer drops below 1.0 Kbps at any time during a download.
• Your download pauses for more than 60 seconds at any time.
• Your download pauses for more than 15 seconds more than once.
• You are connecting to the Internet using a cellular telephone.
• You are connecting to the Internet using a standard, land-based telephone line that sounds noisy when it is used for voice communications.
• You forgot to temporarily disable any telephone service features that may interfere with your Internet connection, such as Call Waiting.
• Your computer unexpectedly disconnects from the Internet at any time.

If you can successfully download files from other popular sites, your Internet connection is likely to be stable. The transfer rate of your downloads should be at least 1.0 Kbps for the entire duration of your download. Most Web browsers will show you the rate of transfer during file downloads.
