Red Hat Bugzilla – Bug 253446
Networkmanager improperly combines 802.11a and 802.11bg with same BSSID

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):
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.
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)'.
I should see both my 802.11a and 802.11bg networks in NM.
Here are the partial scan results:
