Can you search for "essid any" in "/etc/network/interfaces" and replace that
with
"essid private" or whatever your AP is? The reboot the gumstix and see if it
associates
correctly after that .... If that still doesn't work - I'd try rebooting the
WIFi AP just
in case it hasn't gone to a weird state ...

It was working , but it just stopped again. I tried what you said but here
is
what I got.
mwlan0 Scan completed :
Cell 01 - Address: 00:09:5B:6E:BD:F4
ESSID:"private" <-----------That's it
Mode:Managed
Frequency:2.437 GHz (Channel 6)
Quality:0/10 Signal level=-84 dBm Noise level=-96 dBm
Encryption key:off
Bit Rates:11 Mb/s
# iwconfig mwlan0 essid private
Error for wireless request "Set ESSID" (8B1A) :
SET failed on device mwlan0 ; Network is down.
Thanks,
Justin
