168c:002a ath9k - no 5GHz networks

[Tyrael]

I have a Linksys WRT610N Dual-N Band.
I can only see and connect to the 2.4GHz network with ath9k and Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01) 1a3b:1067 (the one on Zotac Ion motherboard, miniPCIe)

That's on a Vaio P11Z

$ lspci | grep -i Atheros
02:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)

With backports-modules installed the laptop does rarely (on startup) connect to my b/g/n network,
and if it connects it is only usable for a short time (or little traffic?) although network-manager
keeps showing the connection as active - I can't even ping the router reliably.

There is no obvious difference between a/n and b/g (couldn't make a successful connection trying a few times).

Without the backports-modules I can connect to the b/g network, but not to the a/n network.

For me the network is always visible though.

[Laryllan (laryllan)]

I can confirm this behaviour of the driver, using
03:07.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)

[Vikram Dhillon (dhillon-v10)]

Can you confirm this issue exists with the most recent Lucid Lynx 10.04 release - http://cdimage.ubuntu.com/releases/lucid/alpha-2/. If the issue remains in Lucid, please test the latest 2.6.32 upstream kernel build - https://wiki.ubuntu.com/KernelMainlineBuilds. Let us know your results. Thanks.

[Tyrael (marco-crociani)]

I'am not sure to be able to confirm this bug because now the PC is at 5/6 meters and 2 concrete wall from the router.
From the same position the MacbookPro sees the 5Ghz network but can't connect.
I tried with http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32.8/ but not with lucid alpha2.

I still have many problems with this card and Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/linux-backports-modules-2.6.31/+bug/414560/comments/187

[Erno Kuusela (erno-iki)]

It seems the ath9k driver restricts you to the region programmed in the card EEPROM, and many (most?) just have it
set to "world" which is the subset of frequencies that are permitted everywhere.

There's a patch to add a regulatory domain override switch at http://patches.aircrack-ng.org/ath9k_regdomain_override.patch which looks like it should help but iwlist freq
still doesn't list the 5 GHz frequencies for me.

(the patch didn't compile cleanly with latest wireless-compat for me, changed the line where
it errors out to say "common->regulatory.current_rd = modparam_override_eeprom_regdomain")

So assuming the bug is with the EEPROM there are two bugs here:

1) failure to provide any indication that the ath9k driver is imposing additional restrictions

2) failure to provide an override for the bad EEPROM

[Erno Kuusela (erno-iki)]

Source for the claim that driver always follows EEPROM is here btw. http://<email address hidden>/msg00921.html

[jerico (jericop)]

I have a WRT600N router and an Atheros AR9287 chipset ( AR5B9X ) and cannot see n networks yet n networks are present as a valid network type in lshw (output below). I am able to connect to b and g networks without any issues. I also checked the EEPROM settings on my ath9k driver setup and got the following below. Are there any other suggestions to help resolve this issue?

Still happens on Maverick. Also just verified that 11n works fine on Windows with same hardware.

[RyanRahl (rahl-ryan)]

I've got the same problem. Card supposedly supports wireless n but I can not use it. This card is a half height pcie AR928X with built in bluetooth that is also not functioning(obviously a separate problem). I'm using Ubuntu 10.10 Netbook Edition on a Dell Mini 10v. I'll try to provide as many details as I can with the following command outputs. Is there any place I can donate money to make fixing this and other bugs faster? I figured that would be the best way to help due to my limited programming skills. I'd really like to use this device in AP/Master mode at Draft-n speeds.
