OK, wlan0 is up somehow and signal strength is good ! You had previously
configured the interface how ?  Or did this come up automatically with
essid "ANY" and in uncertain mode ? What does sudo iwconfig wlan0 give
you ?

Might run with the -d flag to keep in foreground for debugging.

sudo ifdown [eth0 or whatever wired interface]
sudo killall dhclient
sudo iwconfig wlan0 essid XXXXXXXXXHomeNetwork mode managed enc off
sudo dhclient -d wlan0

See what happens.  Is the router configured to accept any ethernet
number for connections ?  Max connections OK ?  What kind of router do
you have ?
