Ad-hoc or Managed WiFi mode?

[Timothy Murphy <tim birdsnest maths tcd ie>]

I'm running my desktop WiFi card in Ad-hoc mode,
but for some curious reason  my laptop only works well
if set to Managed mode.
It works sporadically if set to Ad-hoc mode.

I'm puzzled by this;
it doesn't really matter, as it seems to work perfectly in this way.
But I'd be interested to know why.

I should say that both the cards are Orinoco Gold (Classic),
the one in the desktop being in a PCI-to-PCMCIA adaptor.
I'm running FC-4.
