I was able to reproduce this using my dev laptop and a netbook, both running Precise.
I created the adhoc network on my laptop, then tried and failed to connect using the NetworkManager applet on the netbook. I then dropped to the command line on the netbook and manually connected using wpa_supplicant. This succeeded. Next I cranked up the logging on both NetworkManager and wpa_supplicant to prove that NM was feeding in the right keys and so forth. The keys were right, and I noticed in the output that NM thought that connection was successful and launched the DHCP client. However, those DHCP packets never reached my dev laptop (confirmed via syslog). Now here's the weird part: I attached strace to the NM process and tried to connect via the applet, and it succeeded. Now all subsequent attempts to connect are succeeding. Even creating a new network with a different password, I can no longer reproduce this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1032433 Title: Using WEP 128-bit Passphrase, Ad-hoc connection cannot be established To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1032433/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
