Description (Last modified by mrenzmann)

My atheros/madwifi based card is misdetected by NetworkManager and ends up being shown as a wired network interface. This is probably a bug in how the madwifi registers itself in sysfs or something.

When comparing my working cisco card with the madwifi based one I see this diff in lshal output:

-udi = '/org/freedesktop/Hal/devices/net_00_0d_ed_26_47_0f'
-  info.udi = '/org/freedesktop/Hal/devices/net_00_0d_ed_26_47_0f'  (string)
+udi = '/org/freedesktop/Hal/devices/net_00_11_0a_80_83_b7'
+  info.udi = '/org/freedesktop/Hal/devices/net_00_11_0a_80_83_b7'  (string)
   linux.subsystem = 'net'  (string)
   linux.hotplug_type = 2  (0x2)  (int)
-  net.80211.mac_address = 59813283599  (0xded26470f)  (uint64)

+  info.product = 'Networking Interface'  (string)
   net.interface_up = false  (bool)
   net.arp_proto_hw_id = 1  (0x1)  (int)
-  net.linux.ifindex = 4  (0x4)  (int)

-  net.physical_device = '/org/freedesktop/Hal/devices/pcmcia_351_10'  (string)
-  info.capabilities = {'net', 'net.80211'} (string list)
-  info.category = 'net.80211'  (string)
-  info.parent = '/org/freedesktop/Hal/devices/pcmcia_351_10'  (string)
-  linux.sysfs_path = '/sys/class/net/eth1'  (string)
+  net.linux.ifindex = 2  (0x2)  (int)
+  net.address = '00:11:0a:80:83:b7'  (string)
+  net.interface = 'wifi0'  (string)
+  net.physical_device = '/org/freedesktop/Hal/devices/pci_168c_13'  (string)
+  info.capabilities = {'net', 'net.80203'} (string list)
+  info.category = 'net.80203'  (string)
+  info.parent = '/org/freedesktop/Hal/devices/pci_168c_13'  (string)
+  linux.sysfs_path = '/sys/class/net/wifi0'  (string)

this is diff -up cisco.txt madwifi.txt. Looks like you should be registering the info.capabilities and info.category fields as net.80211 at least. Maybe that will help.

Related ticket: #70.

Probably NetworkManager fails to recognize wifi0 as wireless device because wifi0 has no support for wireless extensions. Can someone please try to find out if this assumption is correct? Or asking the other way round: it would be helpful to learn how NetworkManager determines whether a network card is WLAN or LAN.

I just committed a patch in r1380 that is supposed to solve the problems related to NetworkManager. Please give it a try and let me know if that works.

Original reporter told on #madwifi that issues have been fixed with r1380 and NetworkManager works now. Thanks for the feedback.
