Description Derek Atkins 2007-08-19 17:57:29 UTC
Description of problem:

I've got a D-Link DWL-7100AP that uses the same BSSID for both 802.11a and
802.11bg.  I have them configured with different ESSIDs.  Now that bug #250913
has been fixed the iwl3945 driver shows scan results for both networks properly,
but NetworkManager still improperly combines them.  In the drop-down list I only
see one or the other, but never both networks.

Version-Release number of selected component (if applicable):

NetworkManager-glib-0.6.5-7.fc7
NetworkManager-0.6.5-7.fc7
NetworkManager-gnome-0.6.5-7.fc7
kernel-2.6.22.2-57.bz250913.1.fc7

How reproducible:

This is 100% reproducible.

Steps to Reproduce:
1. Have an a/b/g AP that uses the same BSSID on both wireless networks
2. Setup the wireless networks with different ESSIDs
3. Make sure your kernel reports both networks
4. Watch NM combine them and only show you one network.  Which one seems
   to vary and isn't always consistent.
  
Actual results:

I only see one of my networks.  And indeed right now iwconfig shows I'm
connected to my 802.11a network, and my 802.11a network is in the list, but
hovering over nm-applet says I'm connected to '(unknown)'.

Expected results:

I should see both my 802.11a and 802.11bg networks in NM.

Additional info:

Here are the partial scan results:

Fixed in F8 and rawhide; APs are broken out by band, security, and SSID
