unable to conect means the server is offline or wont let u download and has given up - try downloading a difernt file or searching for the file again or try again later.

waiting to retry means the server is busy, it will keep retrying untill it gets the file or the server becomes unavailable.

most networks that ive used have these sorts of problems all the time but it does depend wot files u r trying to get hold of. many clients just seem to give up cvompletly, however if it is busy gnucleus willl keep searching for it untill it gets it .

if a file is available on many hosts it is a lot quicker to download.
