Description of problem: New-installed F15 doesn't see 5GHz 802.11n wireless network. Very strange, but I've installed it using that network. Installer connected without any problem. How reproducible: Always. (Tried several installations both with i686 and x86_64.) Steps to Reproduce: 1. Install F15 using netinst iso image via 5GHz 802.11n wireless network. 2. Boot it normally. 3. iwlist scan Actual results: A lot of wireless networks listed, all in 2.4GHz band. Expected results: At least one 5GHz wireless network listed too. Additional info: Hardware: HP EliteBook 8440p, Intel Corporation Centrino Advanced-N 6200 (rev 35) wireless device, NetGear WNDR3700 dualband wireless router F14 works fine in the same setup. (However I didn't try to reinstall it.) dmesg outputs in F14 and F15 seems to have no significant differences to me.
what firmware version you are using? Wey
According to dmesg it is firmware version 9.221.4.1 build 25532 both in F14 and F15.
ok, then my next question will be what the PCI subsystem id is? COuld you do the following: #lscpi -mm Thanks Wey

hmm, it is strange, work on F14 but not F15 with the same firmware. If you load the module with debug=0x40, then check the dmesg log. it should give you all the information on what the device belive is "A" capable or not. Wey

The most strange think that it works in F15 installer but not in F15 itself. > If you load the module with debug=0x40, then check the dmesg log. it should > give you all the information on what the device belive is "A" capable or not. Cannot test it until next week, please wait.

don't see anything wrong in the dmesg, both 2.4 and 5.2 GHz are supported. what version of wpa_supplicant you are using? what result you get if you using "iw" or "iwlist" to scan? Thanks Wey
Created attachment 505091 [details] iw list wpa_supplicant-0.7.3-6.fc15.x86_64 iwlist scan shows no 5GHz as I said in the initial post. iw scan gives ... 5220 MHz [44] (disabled) ... (the access point operates channel 44)
by the way iw-0.9.22-1.fc15.x86_64 wireless-tools-29-5.1.fc12.i686
(In reply to comment #10) > wireless-tools-29-5.1.fc12.i686 sorry, it's wireless-tools-29-6.1.fc15.x86_64 actually
Got it work after iw reg set US so it is definitely not a kernel bug. The question now is why it works in F14 and in F15 installer with RU Regulatory domain?
Regdomain is setup by /sbin/setregdomain script. It read files /etc/sysconfig/regdomain file or if it is empty, use time zone information from /etc/sysconfig/clock. To solve this problem you can add "COUNTRY=US" line to /etc/sysconfig/regdomain or configure time zone corresponding to your geographical location (preferred), you can do it using system-config-date command (as root). I'm closing bug as seems issue here is bad time zone setting. Reopen bug if correcting zone setting do not help.
