apt-get, allow only one connection

[Erik Steffl]

  is there any way to restrict apt-get to download one file at a time
only?

  it downloads two of them and one of them timeouts quite often.

  this happens since I moved and now only have 33.600 (I used to have
about 42.000 and it worked ok)

  [haven't found anything realted in man apt-get]

  TIA
