Created attachment 572443 [details] the 5 ghz wireless network ssid Hi; I am using Fedora 16 with the latest kernel (3.3.0-4.fc16.x86_64 ). I have both of 2.4 Ghz and 5 Ghz wireless networks at home.My lenovo L420 notebook has intel 6205 wireless card and there is no problem to connect to 5 ghz wireless network with the same notebook while windows 7 and Linux mint 12 operation systems working. However Fedora 16 can't see the 5 ghz wireless networks. You can find my wireless card information and some error logs about network manager on /var/log/messages below. I have also added a screenshot which was captured the 5 ghz ssid from the same notebook while windows 7 is running. lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b4) 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b4) 00:1c.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b4) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b4) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b4) 00:1c.5 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 6 (rev b4) 00:1d.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 04) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 04) 03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 (rev 34) 04:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

Would you grab an paste output of several commands? $ nmcli dev wifi $ iw phy0 info (ls /sys/class/net/<wlan device name>/phy80211/subsystem/ to get the phyX iterface number) $ iw reg get # iw dev wlan0 scan trigger # iw dev wlan0 scan dump Did you have problems with older kernels?
Yes, There is the same problem with the older kernels. You can find the logs below.

I have just noticed something and I want to give you more information. There are 3 access points which was configured mesh (repeater) at my home. All of the settings are the same (ssid, channel, security etc) in Access points. 5 minutes ago, I set to the factory default one of them and when it was in factory default, My notebook could see the ssid on the air. After I configure it again, My notebook couldn't see it again. My devices are Airties Air4420 and you can find the information about the access points in the following link. http://www.airties.com/product-details.asp?pn=Air%204420&i=2&ci=104&cat1=Wireless+Products+&cat2=AP%2FRouter%2C+Mesh+point%2C+Disk+%26+Print+Server&dil=eng I am also working for Airties in R&D department and we are also using linux in our products. I did double check the settings of Access points. There is no problem other linux distribution and windows 7. if you need more logs, I can do help you. Goksel.
sorry for spelling mistakes, There is no problem with the other linux distribution and windows 7. if you need more logs, I can help you.
The problem appears to be that your AP uses channel 38 (5190 MHz), but the regulatory domain for TR doesn't seem to support that channel. According to http://en.wikipedia.org/wiki/List_of_WLAN_channels however the channel is allowed in Turkey. So probably the regulatory database is not up-to-date. So, I suggest you changed the channel on AP. Or you could set regulatory domain on your computer to another country supporting the channel: # iw reg set BR What version of crda do you have? $ rpm -q crda Links: http://linuxwireless.org/en/developers/Regulatory https://bugzilla.redhat.com/show_bug.cgi?id=480110 http://en.wikipedia.org/wiki/List_of_WLAN_channels
First of all wikipedia is not a trustable source. Second, channel 38 means it uses 40 MHz bandwidth. Below is the explanation for all 5 GHz band and Turkey has UNI-1, UNI-2 and UNI-2Extended.. http://www.cisco.com/en/US/docs/wireless/technology/1140/deployment/guide/1140dep.html
Created attachment 574980 [details] a screenshot which was taken via windows 7.
I changed the wireless channel and also changed the regulatory domain. You can my access point settings and other outputs below. I can't still see the 5 Ghz wireless channel. I have tested it again with windows 7 and I also attached a screenshot which was taken via windows 7.

This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
