Many people use network-manager; I imagine this is mainly because it
gets installed for them. wicd users appear to be refugees fleeing the
real or perceived vagaries of the default network setup software. In
both cases the ability to troubleshoot failed connections does not seem
straightforward.
Network-manager and wicd depend on wpasupplicant. Personally I would
rather deal with the organ grinder than one of the monkeys.
I am going to quote from a mail from a wpasupplicant maintainer:

Success or not with these four lines (after disabling n-m/wicd) gives a
starting point for further investigation.

If wanted, a graphical user interface for roaming is wpagui. The Debian
documentation for wpasupplicant is also very good. Newcomers to Debian
might have the same pleasant experience on a mobile device as I have had
after following similar advice to this.
