With redhead's help I was able to get my Ubuntu server up and running on my WPA encrypted network some time ago.
Since then, I have shut down my server to clean up my office and now after restarting it and running wpa_supplicant and then stopping and restarting the network I still cannot get an IP address.
It appears to be authenticating to the router as it picks up the router SSID, MAC address, etc., but whenever I ping the router I get:
I know this should be an easy fix. Promise to write it down this time.Code:connect: Network is unreachable
Yes, sir. That got me help with wpa_supplicant, which I know now how to startup, but I just don't know why I'm not able to ping my wireless router.
It looks like either it isn't getting a usefull IP address, or the route is messed up.
what IP does it have, what is the gateway IP, what is the default route and whats the netmask assigned to the interface.
Ie output of: ifconfig ath0 |grep 'inet addr:' and route -n
Have you tried specifying to use that interface solely, ie: ping -c 4 -I ath0 220.127.116.11
Don't worry Ma'am. We're university students, - We know what We're doing.

ifconfig ath0 |grep 'inet addr:'
shows no destination, gateway. Nothing.
ping -c 4 -I ath0 18.104.22.168
No such device
