My device has USB ID of 7392:7811. The logged data are as follows:
[ 2.844078] usb 1-1: new high-speed USB device number 2 using ehci-pci
[ 3.120082] usb 1-4: new high-speed USB device number 3 using ehci-pci
[ 22.448552] rtl8192cu: Chip version 0x10
[ 22.649915] rtl8192cu: MAC address: 00:1f:1f:c8:8e:cb
[ 22.649926] rtl8192cu: Board Type 0
I am plugged into an ehci port on my laptop; however, the power-saving feature I
discussed refers to the ability of wireless devices to shut down their power
during a period when no packets are expected. The station (STA) informs the
access point (AP) that it is going into that mode, and the AP will not send any
data until the STA is once again ready. Many drivers have the ability to disable
this feature on module loading, but not rtl8192cu (yet). I am looking into
adding this code.

* [PATCH] rt2x00: rt2800lib: fix band selection and LNA PE control for RT3593 PCIe cards
From: Gabor Juhos @ 2013-09-11 17:56 UTC (permalink / raw)
To: John W. Linville
Cc: linux-wireless, users, Gabor Juhos, Steven Liu, JasonYS Cheng
The band selection and PE control code for the
RT3593 chipsets only handles USB based devices
currently. Due to this limitation RT3593 based
PCIe cards are not working correctly.
On PCIe cards band selection is controlled via
GPIO #8 which is identical to the USB devices.
The LNA PE control is slightly different, all
LNA PEs are controlled by GPIO #4.
Update the code to configure the GPIO_CTRL register
correctly on PCIe devices.

Hi Larry,
For comparison, what does your device report when plugged in? My device
reports this:

Also what type of USB port are you using? I'm plugged direct (no hub)
into a ehci-pci port on a laptop if that makes a difference to power?
ATB,
Mark.

Open a command-line window and enter the command

Possibly, but for reference, my Edimax EW-7811Un has been running for 37 hours.
During that time, I have had no deauthentications and only 2 instances of the
"AP lost" reconnections. The latter is what I am currently trying to fix, but at
that error rate, it is difficult. I am running the latest 3.11 kernel from
wireless testing.
The only thing I am doing that is unusual is that I am pinging my router at a 5
second interval using the command
ping -i5 192.168.1.1
It is possible that I am preventing a power save operation, which is making a
difference.

So the AP is disconnecting the device a couple seconds with reason 4,
which is "Disassociated due to inactivity". My thought is that this
points to a driver bug (Larry?).

* [PATCH 2/2] ath9k: Fix PeakDetect calibration for AR9462
From: Sujith Manoharan @ 2013-09-11 11:06 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
In-Reply-To: <1378897592-19199-1-git-send-email-sujith@msujith.org>
From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
Since HW PeakDetect calibration is turned on for AR9462,
various conditions have to be handled in the driver:
* Enable agc_cal when loading RTT fails.
* Disable SW PeakDetect calibration when RTT calibration is not enabled.
* Keep SW PeakDetect calibration result in driver.
* Update RTT table according to the saved value.
* Write RTT back after modifying SW RTT table.
* Enable local mode for PeakDetect calibration and restore values.

minstrel and minstrel_ht always keep low rates in the rate retry chain
until enough higher rates have been proven to work.
I think adding an interface that allows user space to mess with the rate
selection of EAPOL packets is a bad idea - users will pretty much always
make worse rate decisions than the rate control module.

This is a firmware issue that has been fixed in later versions that we
haven't released yet. I hope that I will able to release the new

the version numbers are not successive (4 -> 0x11), so i think it
makes sense, but i guess we can revert back to array if you prefer it

you're right here.
untrimmed devices always use the 0 value.
i'll split it to "untrimmed" and "unknown".

i'm not sure what "not supported" actually mean here (it might still work...).
i'd prefer continue using these values only for debugging (there
shouldn't really be such unsupported devices out there, afaik)

i can see the calibrator calls various WL1271_TM_CMD_TEST commands, so
i guess they are likely to end up with ps_elp_sleep() calls (in
wl1271_tm_cmd_test()).

this is quite minor patch (only making sure we always define hardirq

* iwlwifi crash with "Microcode SW error detected"

[1]iwlwifi crash with "Microcode SW error detected"
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1221202
[2]
I have an intel 7260 wifi card (it is a dual band). I have had a
**lot** of trouble connecting to my router (also dual band). I don't
know how I did but I eventually managed to connect to the 2.4GHz AP but it is not
very stable. However, I've never managed to connect to the 5.5GHz AP
while it is listed as available. By looking at dmesg, the driver is
crashing:

* [PATCH 2/3] ath9k: Fix issue with parsing malformed CFP IE
From: Sujith Manoharan @ 2013-09-11 6:10 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
In-Reply-To: <1378879859-32290-1-git-send-email-sujith@msujith.org>
From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
All QCA chips have the ability to parse the CF Parameter Set
IE in beacons. If the IE is malformed in the beacons from some
APs [1], the HW locks up. In AP mode, a beacon stuck would happen
and in client mode, a disconnection usually is the result.
To fix this issue, set the AR_PCU_MISC_MODE2_CFP_IGNORE to ignore
the CFP IE in beacons - this is applicable for all chips. For
AP mode, if this issue happens, the NAV is also corrupted and has
to be reset - this will be done in a subsequent patch.

* [PATCH 3/3] ath9k: Handle abnormal NAV in AP mode

Beacon transmission would get stuck if the NAV is
an invalid value for some reason. Check and correct
the NAV value in the HW when this happens.

* [PATCH 1/3] ath9k: Fix calibration for AR9462
From: Sujith Manoharan @ 2013-09-11 6:10 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
TX IQ calibration is disabled by default for AR9462, this
is done using the initvals (reg 0xa644).
But, to compensate for this, the AR_PHY_RX_DELAY register
should be set to the max allowed value when performing
calibration.

Thanks for your code and for documentation!
I see you did your work in a new net/wireless/rtl818x/rtl8187se
directory and you produced a new driver.
Now I have to evaluate whether to keep doing it in this way, trying to
continue your work, or to merge support in
net/wireless/rtl818x/rtl8180 code, that was my original idea..
Now that I have documentation I can better evaluate how much the two
boards are similar..

I didn't know that. Thanks!
