When you installed wicd, did you remove networkmanager? If you don't do
that, both nm and wicd would fight each other configuring the wifi
interface. In the end none of them wins and there is only intermittent
OTOH, if you made sure that only one of nm or wicd wass installed at a
time, I would assume that the reason is the kernel driver for your
hardware. You can find out which hardware is installed in your machine
with the command
sudo lshw -C network
in a terminal. If you tell us which hardware is in use, it may be easier
to determine what could be done to achieve a reliable wifi connection.
