Hi Guys
Need some extra eyes on this. I'm hoping its something simple that I've
missed...
I have an embedded PC installed with Ubuntu 12.04 Server edition on a
site. During installation I've set it up to use WiFi as its primary
connection as that's the only option available where it will be
installed. During installation it recognised the WiFi connection and
seemed to connect, but after reboot the connection doesn't work.
What baffles me is that everything I'm doing is telling me that it
should connect. Right now I have it on the table with me and connected
it to my PC with a network cable so I can capture the output testing.
PS: my laptop is currently connected to the WiFi network without any issues.
So here's the setup in /etc/network/interfaces:
# The primary network interface
auto wlan0
iface wlan0 inet static
address 192.168.1.201
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
wpa-ssid FuelSure
wpa-psk MyLongPassword
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.1.1
The Interface appears to be up:
$ iwconfig
wlan0 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on
The connections seems to be configured
$ ifconfig
wlan0 Link encap:Ethernet HWaddr 6c:62:6d:12:d5:fb
inet addr:192.168.1.201 Bcast:192.168.1.255 Mask:255.255.255.0

I've checked the start up process...
$ sudo ifdown wlan0
$ sudo ifup -v wlan0

And when I scan the network also appears...
