Same problem on a Thinkpad with Kubuntu Hardy Final and iwl4965. I'm able to connect manually, but then I experience random network-related hangups: the machine doesn't even respond to sysRq sequences and has its Caps Lock LED flashing.
Basically, i have to paste each time this sequence: sudo ifconfig wlan0 down&&sudo iwconfig wlan0 mode ad-hoc&&sudo ifconfig wlan0 up&&sudo iwconfig wlan0 essid winet&&sudo iwconfig wlan0 key XXX &&sudo route add default gw 192.168.0.1 since on boot it seems iwlwifi ignores the ad-hoc mode set in /etc/network/interfaces -- iwl3945 doesn't support ad-hoc networks https://bugs.launchpad.net/bugs/201597 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
