I have a 4965, using kernel-2.6.29-0.197.rc7.fc11.x86_64 (Intel(R)
Wireless WiFi Link AGN driver for Linux, 1.3.27kds). I can connect to
802.11n on 2.4 GHz, but it never finds the 5 GHz cell of the AP. Is 5
GHz 802.11n supported yet? For that matter, shouldn't I be seeing the
802.11a from my APs? How do I get this thing to scan the A/N 5 GHz
band?
Thanks.

Ah, the joys of Rawhide...
Make sure you have "iw" installed.
yum install iw
Then you need to specify your regulatory domain:
iw reg set US # Use ISO/IEC 3166-1 alpha2 as appropriate for you
Does that change things for you?
We are still discussing ways to get this set automatically. We are
hoping that NetworkManager grows this capability "soon"... In the
meantime, you might try calling the attached script from /etc/rc.local.
Hth!
