When I first encountered the error when downloading the pset3.zip file for problem set 3, I wasn't very worried because the pset3 html had directions on what to do for when that happened. It said that the probable cause was no internet connection, and that I simply had to log off and re-log back into the appliance. After trying that multiple times, I still have the 'unable to resolve host address' message. I looked in the settings of the appliance, it seems to be connected to the internet, but I'm not too sure (there are three wireless connections). Am I missing something? Any help or suggestions will be appreciated.
Are you sure you are executing the following command as it is?
For me it works fine, so it's not a problem on their side. Can you browse the internet from Chrome? If not there is something wrong with your connection. If you can, click the following URL and it should download the zip file. http://cdn.cs50.net/2014/fall/psets/3/pset3/pset3.zip
