More testing on my part is indicating that the cause appears to be:
iface wlan0 inet dhcp
Evidence is indicating that the above is required to be in
/etc/network/interfaces.
Previously, I also had the wifi's essid and password. Now, I moved the
essid and password to another file under /etc/network/interfaces. I
was able to reproduce the same behaviour as experienced by fsmithred.
Now my setup works.
With my setup I was able to connect to various wifis not just the one
at my home. This means, my configuration works and was far more stable
than what I was experiencing using wicd.
