Alfa AWUS036NHR with RTL8188RU chipset

Alfa AWUS036NHR with RTL8188RU chipset

[Chiefdome]

Hi there,

i just bought an Alfa AWUS036NHR for testing.
It runs with the rtl8192cu driver.
I have a question because sometimes the wireless adapter dont shows any 
networks no longer.
I have to reload the module an then its showing some networks.

In dmesg it shows:

[  262.219575] ADDRCONF(NETDEV_UP): wlan1: link is not ready
[  269.770133] ADDRCONF(NETDEV_UP): wlan1: link is not ready
[  270.947047] ADDRCONF(NETDEV_UP): wlan1: link is not ready


For any further output please let me know.

What kernel? There are some problems with kernels prior to 3.1 in connecting to 
802.11n networks, and also a problem in clearing the keys. Both of these 
problems are fixed in the latest compat-wireless.

I tried at least wireless-next but the adapter isn't showing up.
Where to get more log files and stuff?
Isnt this adapter good supported by the rtl8192cu driver or where is the 
problem?

I have no idea as the only AWUS036 I have is the old one with an RTL8187 chip.

I have been running a wireless-testing 3.1-rc6 kernel with an RTL8188CUS chip 
(USB IDs are 7392:7811) with no problems. George will know more about supporting 
that chip than I do.

I will boot my mainline kernel, but I think it is OK.

If the adapter isn't showing up in wireless-next, you need to check the USB IDs 
using lsusb, and compare them with the USB_DEVICE tables in 
drivers/net/wireless/rtl8192cu/sw.c. The only place that logs will occur is 
dmesg, /var/log/messages, or /var/log/syslog.

For the mainline kernel to work with 802.11n-only APs and to reconnect after an 
initial try, your kernel needs the following patches:

     rtlwifi: rtl8192su: Fix problem connecting to HT-enabled AP

     The driver fails to connect to 802.11n-enabled APs. The patch fixes
     Bug #42262.

Both of these are in wireless-testing, and were just merged into the mainline 
kernel. In addition, they were merged with the 3.0 stable tree today.

Both should be in wireless-next, but as I recall, you were not able to test with 
that tree.

With the updated mainline kernel, the link is stable and performance is 
acceptible with netperf TCP_STREAM (TX) at 20.5 +/- 4.8 Mbps and TCP_MAERTS (RX) 
of 21.7 +/- 3.8 Mbps. These numbers are not spectacular, but they will do.

I tried the latest git repo from 
git://git.infradead.org/users/linville/wireless-next.
Same story here.
After disconnecting to the network, I have to reload the module only 
then networks are seen.

I just cloned the wireless-next tree. The two patches mentioned in my previous 
Email are included.

Please run the following command sequence and send us the dmesg output after 
your failure occurs:

modprobe -rv rtl8192cu
modprobe -v rtlwifi debug=3
modprobe -v rtl8192cu

I have found another bug - it is impossible to me to connect a 
WPA2-network - here is the dmesg output for that - will send you the 
output for a WEP-network later then:

The first thing I notice is that you apparently do not have CRDA installed. A 
second thing is that the interface never comes up. As long as it remains down, 
it can never connect. How are you connecting? I'm using NetworkManager.

The following is an excerpt from my dmesg log with debug=3 set when rtlwifi is 
loaded:

As you notice, this connection uses the CCMP algorithm, i.e. it is with 
WPA2-AES.  It is also an 802.11n. Just to test, I switched the AP to run only at 
802.11g rates. That also worked.

I need to know more about your setup. What AP and how is it configured? How do 
you control the wireless connection?

The AP showen above is configured as you say as an 802.11bgn device. The 
wireless connection is controlled by wicd.

I just reviewed our entire correspondence on this issue. I could not find where 
you specified the make and model of the AP.

I have never used wicd, but several people on the openSUSE forums abandoned it 
because it was buggy. Are you sure it is not the problem?

What would you suggest to use to make a wireless connection from the gui?
With network-manager I have the same problems.

Sorry I forgot to say what the AP is, it is a FritzBox 7270 v2.

It seems that we are converging on an incompatibility between that FritzBox 7270 
and rtl8192cu as a problem.

*George* Do you have one in your Lab? As the price on EBay is $275 US, I'm not 
very interested in getting one.

*Chiefdome* Would it be possible for you to run Wireshark on some other machine 
and send us the capture file for the attempt to connect? When you use WPA-TKIP 
encryption, does it work? I would also appreciate your using 'git log' and 
verify that commits bac2555c6d863871329 and 3401dc6eba788ebc7c is present in 
your source.

hello larry,

i've an ALFA AWUS036NHR and i tried latest compat-wireless-2011-09-27 on ubuntu
natty 3.0.4-030004-generic, 
the adapter is recognized as rtl8192cu but is not
responding, no network is detected.

Then if i try to "modprobe -r rtl8192cu" results
FATAL: Error removing rtl8192cu
(/lib/modules/3.0.4-030004-generic/updates/drivers/net/wireless/rtlwifi

seems that remains blocked..i can't do anything

tried dmesg and it says

You are the second person that has reported a problem with this device. 
Unfortunately, I do not have a sample of the device, but I have just ordered one 
that will be delivered in about one week. I would guess that there is some 
difference between the RTL8192CU and the RTL8188RU chips.

I Cc'd the Realtek group that works on USB devices. Perhaps they have some info 
that will be useful. Given the difference in time between the US and Taiwan, I 
would not expect any answer until Monday.

There are some changes that affect connection with an 802.11n network that are 
found in the latest kernels. I'm not sure they are in the one you are using. You 
can get the very latest by downloading and building the "bleeding edge" version 
of compat-wireless.

Re: Alfa AWUS036NHR with RTL8188RU chipset

[v4mp]

ok thx for reply, i just like to say to you that i have tryed beini tiny core
1.2.3 that was patched to support this type of usb device with the latest
update, and it works with rtl8192cu (and the blue led is working)

i've extracted a .tce module from the beini that seems to be rtl8192cu modded
driver,

this is the link i've uploaded on fileserve
http://www.fileserve.com/file/9mZxX5T/x_rtl8188ru_20110812.tce

maybe it could be useful, thx :)

Re: Alfa AWUS036NHR with RTL8188RU chipset

[Toddy]

Hello,

I also have the AWUS036NHR device and I got it working on Ubuntu 11.04
2.6.38-11-generic x64. The only thing I did is to compile&install
compat-wireless-2.6.39-1 (same as beini!) which can be found here:
http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.39/

There was only one strange thing: In drivers/net/wireless/rtlwifi/rtl8192cu/sw.c
there is no entry for the AWUS036NHR so that no driver is loaded when I plugged
the USB in, but in older versions of compat-wireless (e.g. 2.6.38) there IS one
entry for this device. The entry looks like this:

/* 8188RU in Alfa AWUS036NHR */
{RTL_USB_DEVICE(USB_VENDER_ID_REALTEK, 0x817f, rtl92cu_hal_cfg)}

So I patched the file, compiled&installed it and everything worked! Could
someone patch the sources and add this device? Thanks!

The device is already in the kernel source.

Your choice of a compat-wireless version is what caused the problem. That device 
was added to wireless-testing code on Aug. 5, 2011. By choosing an older version 
of compat-wireless, you did not get that patch. For best results, you should 
always choose the bleeding-edge version of compat-wireless.

Re: Alfa AWUS036NHR with RTL8188RU chipset

[Toddy]

Hello Larry,

thanks for the quick reply! Yes I know this version is a bit older, but when I
use the newest compat-wireless (eg.
http://www.orbit-lab.org/kernel/compat-wireless-2.6/compat-wireless-2011-10-07.tar.bz2)
the driver loads but some features like monitor-mode and packet injection
doesn't work. The listing of available networks (with airodump) doesn't work
too. Usually I have 13 channels because I live in Germany but if I use the
newest driver I have only 11 channels. But if I use the older compat-wireless
package all works fine.

The difference between 11 and 13 channels depends on your CRDA settings. Do you 
have that package installed? Check the output of dmesg to see what domain is 
being set. If you have CRDA installed, then you can force the use of Germany in 
the domain by creating a file named /etc/modprobe.d/50-cfg80211.conf containing 
a single line with "options cfg80211 ieee80211_regdom=DE" (without the quote marks).

You can get a list of available networks using iwconfig or iw. I know those work.

As I do not test, support, nor condone packet injection, I cannot speak to it 
working on any driver.

Well, packet injection is required for Hostapd to work.

Sorry, but i can't get this Alfa product to work with the latest bleeding edge 
compat-wireless-2011-10-08 on ubuntu 11.04, tryed with kernels 2.6.38-11, 
2.6.39 rc4 and 3.0

i tryed also the 2.6.39-1 version of compat-wireless

Don't show anything in managed and monitor mode..

I do not know about monitor mode, but the Alfa device works in managed mode with 
kernel 3.1-rc9 from both wireless-testing and mainline. I use NetworkManager. 
All of this current code should be in the latest bleeding edge compat-wireless 
version.

Have you installed the firmware?

Larry

Re: Alfa AWUS036NHR with RTL8188RU chipset

[v4mp]

i've tried also kernel 3.1-rc9 with latest compat wireless 14-10-2011 and still
don't work...it was recognized but no APs can be detected..the led of the alfa
is off..seems that it is power off..

i don't know about firmware, i see that there are .bin on lib/firmware/rtlwifi..
 how can i update them?

That depends on your distro, but please look at the output of the dmesg command 
to see if there is an error loading the firmware.

You also need to install rfkill and look at the output of 'rfkill list'. If you 
have another wireless device that is being hard blocked, or if there is a soft 
block active, then rtl8192cu cannot work.

Note that the device works on my system. There should not be a problem with the 
driver on your device once we clean up these questions. Once the device gets the 
proper firmware and the RF is unblocked, the LED will light.

Larry

Re: Alfa AWUS036NHR with RTL8188RU chipset

ok, i've attached the alfa and run rfkill list but it shows that there are no
blocked devices, then i run modprobe rtl8192cu and strangely the alfa has
lighted, but it doesn't work..

Those errors look as if the device was removed before unloading the driver. That 
is a known problem with the driver.

The firmware is available in the linux-firmware git repo, and should be in your 
distro's firmware package.

Only one version of the firmware has been published. The md5sum output is

943e9b714a926e630b8152d7aad91d2e  /lib/firmware/rtlwifi/rtl8192cufw.bin.

Please reboot your system, try to connect, and then post your entire dmesg 
output at pastebin.com. Report the link here.

Re: Alfa AWUS036NHR with RTL8188RU chipset

ok, i've checked the md5 checksum of the firmware and is ok,
i give you dmesg at pastebin.com

it has 2 parts: in the second part i can't see what is in previous of the error

There are a number of USB errors, all occurring on the xhci controller. Do you 
have any USB ports on different controllers? What is the output of lsusb?

Please try blacklisting xhci-hcd by adding a line containing
"blacklist xhci-hcd" to the end of /etc/modprobe.d/50-blacklist.conf.

Re: Alfa AWUS036NHR with RTL8188RU chipset

i tested the compat wireless drivers with another alfa awus036h and it works
well, i tested also the realtek linux drivers 8192cu and the alfa awus036nhr
works with them in the same distro and same kernel
with rtl8192cu and xhci_hcd there are these no room on ep ring errors :(

I'm confused about what you did.

The Alfa AWUS036H uses a completely different driver (rtl8187) than does the 
AWUS036NHR (rtl8192cu). It has been in the kernel for several years, thus using 
compat-wireless would not be necessary.

Are you saying that driver 8192cu from Realtek's web site works with your 
system, but that the kernel version from compat-wireless does not? If that is 
true, what is the exact file name of the driver you downloaded?

Larry

Re: Alfa AWUS036NHR with RTL8188RU chipset

[v4mp]

 

yes, i know that the awus036h uses a different driver, 
i just wanna say that it 
has no conflicts with xhci_hcd as happen when loading 
the rtl8192cu driver for the 036nhr

the driver i downloaded from realtek is what you can find here
http://www.alfa.com.tw /in/front/bin/ ptlist.phtml?Category=105397
for the awus036nhr, and it works fine without any kind of errors,
 detection of APs and connections

every compat wireless i download does not with rtl8192cu and my alfa,
i tested all the specific kernel version of compat-wireless and the latest 
bleeding edge compat wireless, i'm hating this fuckin errors :)

And I get really pissed off at people that have bleeding-edge hardware and get 
mad because a driver doesn't work. Do you want to debug this issue by yourself? 
If not, then you had better control your temper and your language. I am just a 
volunteer. From what I see on my computer, the device, which I bought with my 
own money, works fine. Thus - no problem.

i don't know why you are saying this, i was just kidding....

i think i'm doing a favour to you too debugging this..

however with the rtl8192cu the hardware doesn't work with 
the ep error related to xhci_hcd..
it is the point that we are now

there is something more can i do now?
 i don't have any other usb port that works with other controller like ehci..

You can set up usbmon and dump the starting USB traffic for rtl8192cu and for 
the Alfa driver, but please do not let it run for a long time. Those dumps get 
very long. Load the driver you want with the device unplugged, then plug in the 
device, and dump the buffer 3-4 seconds later. The instructions for using usbmon 
are at http://www.mjmwired.net/kernel/Documentation/usb/usbmon.txt or in 
Documentation/usb/usbmon.txt in the source tree.

The other thing you could do is to plug in the device with rtl8192cu as the 
driver and after 1 second dump the dmesg log with 'dmesg > dmesg.out'. In your 
previous attempt, you let the buffer wrap around and important info was lost. 
These logs should be posted at Pastebin.

I sent a request for info regarding this to the Chinese group that wrote the 
driver, but I have not heard back.

Larry

Re: Alfa AWUS036NHR with RTL8188RU chipset

I got the data. Thanks. It will take a while to analyze the usbmon data, but 
there is something I would like you to try. It will involve getting the kernel 
source for some recent kernel, and applying the attached patch. With it, 
xhci-hcd will dump the stack whenever the "short transfer on control ep" or "no 
room on ep ring" errors occur. Send me those parts of the dmesg output, but 
again do the dump early before the buffer wrap around happens.

Is there a way to set the tx-power over 20dbm on the adapter?
I thought it is able to do 2w. There is no way for me to get it over 20 dbm.
When trying to to set the adapter with "iwconfig wlan1 set txpower 30" 
it answers

Error for wireless request "Set Tx Power" (8B26) :
     SET failed on device wlan1 ; Invalid argument.

I think there has to be done some work in the code but where do I start?

The WEXT interface is deprecated. It is there as a convenience, but it will not 
be extended. To change the power setting, you need to use the iw utility. The 
specific commands are:

iw dev <devname> set txpower <auto|fixed|limit> [<tx power in mBm>]

or

iw phy <phyname> set txpower <auto|fixed|limit> [<tx power in mBm>]

The maximum power will be dependent on your regulatory domain setting.

Did you tested the commands you posted to me? Anyway here they do 
nothing. I cant see any changes in iwconfig nor in in iw.

iw reg get
country 00:
     (2400 - 2494 @ 40), (N/A, 33)
     (4910 - 5895 @ 40), (N/A, 33)

so after my regulatory domain I should be able to change the adapter 
settings.

No, I did not test them. If they don't work, then you need to debug cfg80211. 
These things are not a part of the driver. It only does what it is told.

You need to set a proper regulatory domain. Yours says "country 00", which is 
not right. Mine says

finger@larrylap:~> iw reg get
country US:
         (2402 - 2472 @ 40), (3, 27)
         (5170 - 5250 @ 40), (3, 17)
         (5250 - 5330 @ 40), (3, 20), DFS
         (5490 - 5600 @ 40), (3, 20), DFS
         (5650 - 5710 @ 40), (3, 20), DFS
         (5735 - 5835 @ 40), (3, 30)

and that 27 dBm exactly matches what iwconfig says.

I now have tested. My device is limited to 27 dBm, thus the limit in the txpower 
command is 2700, but one can reduce the power.

With your regulatory info, you should be able to get 3300, unless the rtl8192cu 
firmware has a limit to keep you from destroying the chip.

Perhaps you should ask Alfa about this issue.
