Detecting 5GHz wireless networks

[Dann Church <dann church cassatt com>]

I am running Fedora 9 with NetworkManager-0.7.0-0.9.3.svn3623 on a
laptop with a Intel 4965AGN wireless card.

With this setup, I can connect to networks on the 2.4GHz frequencies
just fine.  However, I have (both at work and at home) a wireless router
that are dual-band and have unique SSIDs for the 5GHz bands, and cannot
connect with NetworkManager to the AP using these frequencies.

>From iwlist scan, I see:

wlan0     Scan completed :
          Cell 01 - Address: <my AP mac here>
                    ESSID:"dd-wrt-5G"
                    Mode:Master
                    Frequency:5.18 GHz (Channel 36)
                    Channel:36
                    Quality=49/100  Signal level=-79 dBm  Noise

                        Pairwise Ciphers (1) : CCMP
                        Authentication Suites (1) : PSK
                    Bit Rates:6 Mb/s; 9 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s

                    Extra:tsf=foo

which clearly shows the frequency/channel info, but in nm-tool:

- Device: wlan0

  Wireless Access Points
    dd-wrt-5G:       Infra, <my AP mac here>, Freq 0 MHz, Rate 0 Mb/s,
Strength 55 WPA2

In /var/log/wpa_supplicant.log, I just see:

Trying to associate with <my AP mac here> (SSID='dd-wrt-5G' freq=0 MHz)
Authentication with <my AP mac here> timed out.

In /var/log/messages, I have:

Any debugging to do to see why we're not seeing the frequency?  Also, is
this the reason we're not getting a successful association with the AP?

You would if you could but you can't so you won't.
