Sorry, I should have been clearer.  What happens is that the download
simply hangs.  Doing ftp I turn on the 'hash' option so the ftp server
prints a # for every 1k (or something?).  It'll print a half a screen
full of #s then stop; and I won't get the "ftp>" prompt back, even
should I wait a half hour for it.

Using wget it's pretty much the same idea.  On the left of the display
it'll show something like this:

and just freeze there... except the right two numbers (following "eta")
will continue to climb higher... it stays at "5%" and "1,029,216"
doesn't change, and there's no activity between those two numbers.  In
short, the download just stops or freezes.
