The install seems to be stuck on phase 3.1 downloading aster

How long should it take to complete the download of asterisk,libpri,zaptel,and wanpipe source . (phase 3.1 on server install ISO)
It has been on this for over an hour. I have a 8 meg download. At what point do I start over or pull the plug, will it say no internet connection if it can't access Internet for download.
Any help be appreciated.
