Bug Description
I tried to set up a wireless ad-hoc network with my atheros wlan chip. But I did not get it work because the ath5k driver seems to be corrupt. After a few seconds the ESSID changed to a random value.
The following script reproduces the error:
ifconfig wlan0 down
iwconfig wlan0 essid "WLAN" mode Ad-Hoc channel 3
ifconfig wlan0 up
iwconfig wlan0 # correct output
ifconfig wlan0 down
iwconfig wlan0 essid "WLAN" mode Ad-Hoc channel 3
ifconfig wlan0 up
sleep 3
iwconfig wlan0 # incorrect output
I got the following output:
root@ubuntu:
wlan0 IEEE 802.11bg ESSID:"WLAN"
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
wlan0 IEEE 802.11bg ESSID:"
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
As you can see the ESSID changed to a random string after a delay of 3 seconds. So I can not set up a ad-hoc network ...

summary: |
- network-manager misspells the ESSID for ad-hoc networks + network-manager misspells the ESSID for wireless networks |
I noticed that this bug only occurs if I don't stop the network-manager. So I seems that the network-manager in Ubuntu lucid changes the ESSID!
(service network-manager stop)
