You have been subscribed to a public bug: Hi, I recently migrated to a new laptop, and wicd had trouble detecting the wireless interface on it. I'm using Debian sid on a Toshiba dynabook RX2/T7J.
GetWirelessInterfaces() in wnettools.py looks for /sys/class/net/*/wireless, but there's no such file on my system. Changing this function to invoke iwgetid on every interface and look at the exit code solved it (see attachment). It works, but it's rather inefficient. Speaking of which, should the detection code be moved to backends? There could be an ioctl version of iface detection. That may or may not be useful since this is a one-shot thing that gets run at startup, and besides, there are only so many interfaces to check.... I chose iwgetid over iwconfig because of this bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=526187 (Summary of the linked bug report: "iwconfig foo" returns 0 even if foo is not a wireless interface.) There is a related bug, which is that the default values of the interfaces were never used. My wireless interface was in fact wlan0 (the hard-coded default), but wicd didn't try that interface. In WicdDaemon.ReadConfig(), a default is assigned when iface receives the value None, but this never happens because the WirelessDaemon.DetectWirelessInterface() applies str() before returning the value, and turns the object None into the string "None". Removing the str() hasn't caused a problem for me so far, but is it needed for some reason? Finally, can wicd show a warning if it couldn't detect any wireless interfaces? I think the user should be alerted when there is a potential problem. ** Affects: wicd Importance: Critical Assignee: David Paleino (dpaleino) Status: Fix Committed ** Affects: wicd (Ubuntu) Importance: Undecided Status: New -- wicd can't detect wireless interface https://bugs.launchpad.net/bugs/415719 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
