Bug Description
AR9485 Wireless Network Adapter has a low signal when in close range of station.
I disabled hardware encryption with putting:
options ath9k nohwcrypt=1
in
/etc/
That doesn't seemed to help.
The signal has 2 bars while it has full strength in windows. (I am 2 meters away from the wifi station)

Hi Joseph,
No that is not possible because I use the installation for serious

It's not just the signal that is low, it also disconnects frequently. (Quantal neither had low signal nor disconnected in the same situation.)

I tried upgrading kernel to 3.9, but the poor connection signal persisted. Then I installed compat-drivers from:

now the connection signal is better than before. Not as good as with windows, but I get to connect in places where I couldn't before.
To try this you need to:
- download the drivers that match your kernel version. In my case, I downloaded compat-

- cd Downloads/

There is no known workaround for this yet.
I used to work well in Ubuntu 12.04, with "options ath9k nohwcrypt=1".
I am using Ubuntu 13.04 x86-64 with packages up to date.
Tried compat-drivers 3.8.3-2-snpu and 3.9-rc4-2-su with no luck.

My UX31E also disconnect often. I do have signal, but weak. It doesn't disconnect as often when I'm closer to the router.
What I want to report that I have not seen anyone else mention is that it will only behave like this when on battery. I have turned off power saving (iwconfig wlan0 power off) but that does not help.

I have tried 3.9 kernel and the compat drivers without any improvement.
Does anybody know if this problem is present in 32-bit version as well?

The second patch is applicable for a specific model of AR9485. Can you please attach the output of "dmidecode" to this bug ? Also, the contents of "modal_eeprom" in the ath9k debugfs directory.
The power management issue appears to be different, so we can analyze it in a new bug report.

Thanks.
Here is a patch adding support for this card:

Can you test this ? This will apply on top of the earlier patch ("Assign default xlna config for AR9485").
Also, after you explicitly unload/reload ath9k (modprobe -r ath9k; modprobe ath9k), the line "Set parameters for CUS198" should be seen in dmesg.

Applied first https:/
Patch(1) applied it with some fuzz and I had to manually apply the patch to pci.c.
Seems to work fine with a short test: decent bandwidth, keeps up, shows 65 Mbps as rate, link quality between 40 and 50, and I get the kernel message:
ath: phy1: Set parameters for CUS198
I can test later with some other kernel versions if needed.

I need a few precisions :
- do I have to apply this patch only ?
- on top of the 3.10-rc5 kernel ?
- with powersave mode off ?
- what do I have to post (logs...) after testing ?

Sorry I'm a kernel newbie...
How can I download Linus' tree ?
Previously, I downloaded the sources from kernel.org

Hm, in that case, you can just apply the patches on top of the 3.10-rc5 tarball.

Applied with some fuzz, no manual intervention required, results look the same
as with 3.8.0 and 3.9.5.

Out of topic probably, but as I see that bluetooth is in the same device: seems like there is a problem with bluetooth also, but could be something else than the driver. Device is found, hciconfig shows bytes sent and received, but hcitool scan doesn't show devices.

Yes, ATH9K_RATE_CONTROL has to be disabled.

Ok, I am not familiar with bluetooth - I'll try to get more information.

Ah, I wondered I might have forgotten something with my 3.8.0 test - now I remember, it was ATH9K_RATE_CONTROL:
# grep RATE_CONTROL .config
CONFIG_
Seems to work quite well even with this.
For 3.9.5 and 3.10 I had it disabled:
# grep RATE_CONTROL .config
# CONFIG_

So I've applied both patches on top of the 3.10-rc5 kernel.

However, it looks like powersave is on by default (I've removed the item in /etc/pm/power.d that disabled it) :

Link quality seems to have improved a lot :
- in 3.8 without patches, "iw dev wlan0 link" shows me "signal" between -74 and -86 dBm
- in 3.10-rc5 with the patches, it shows me "signal" between -55 and -62 dBm
I'll do futher testing and report here.

The PS/rate-control patches will be in -rc6.

I've been using it with all doors closed at home and experienced no disconnection and no lag.
Looks really great !!! :-)

No problems here either, seems to work fine in longer term (well, a few hours) use too. Power management has been on for me though so far, will try with power management off.
In Linux Kernel Bug Tracker #49201, jkp (jkp-linux-kernel-bugs) wrote : | #206 |
With power management off, when I look at the iwconfig bit rate every five seconds, it's mostly 65 Mbps but about every once in 25 .. once in 50 it's 1 Mbps.
In Linux Kernel Bug Tracker #49201, jkp (jkp-linux-kernel-bugs) wrote : | #207 |
With power management off, occasionally there are longer periods of low speed (1..30 Mbps) and this affects also practical usability quite a lot.

I tried the 3.10-rc6 on ubuntu 13.04 amd64. No improvement. I assume the
patch did not make it into rc6.
I tried the script for updated kernel 3.10-rc5 that Xcalin posted. I have
yet not tested it to depth but so far it seems to be working great. Better
connection. So far no disconnections. I am very satisfied.
Thanks a lot!
