Won't enter restricted mode. What am I missing? -- This worked two days ago...
Internet comes in via wifi, was using a windows server to then share that out via ethernet. Just installed latest Ubuntu Server 8.x.
I was able to connect on sunday via linux server, and still am today via windows desktop machine, but not via linux server any longer. The problem seems to be that I can't get the wlan0 interface out of Open mode.
iwconfig wlan0 key restricted xxxxxxxxxx
iwconfig wlan0 enc restricted xxxxxxxxxx
iwconfig wlan0 key xxxxxxxxxx restricted
iwconfig wlan0 enc xxxxxxxxxx restricted
and many others, yet every time I "iwconfig wlan0" it shows its network key, and it shows it as being "Open". I swear I remember it working before I ran dhclient on sunday when it worked (that was the day I did the install).
Now dhclient just fails every time.
I am setting essid, and channel properly. It's just this one thing I can't figure out. The man pages seem to indicate that once I set a key it should automagically go into restricted mode.
Welcome to LQ!
If I remember correctly, Ubuntu uses ifup, not dhclient. You might give that a try and see if it behaves better than dhclient. Also, have a look in your logs and see if dhclient/ifup are leaving any errors that might give us a clue as to what is going wrong.
