Fwd: Re: TP-Link 8200ND - rtl8192cu module not loading / working

[shiki.biomernok]

Hello everyone!

CC'ing my original message that I sent to Larry.
It's been a while, but I've been busy and I couldn't fiddle with the 
wireless device.

Basically it's a 8192cu device. Larry suspected it's not, but I think he 
saw the advertisement displayed on top of the TP-Link page.
I even mailed TP-Link, and here is the reply:

    The chipset is Realtek RTL8192CU and you can download the driver
    from
    http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true.
    Thank you.

Tested with many kernels, but none of them worked.
Ubuntu 13.04 (both stock + updated), Fedora (Schrodinger-1), Fedora Beta 
(Schrodinger), openSUSE (normal+tumbleweed).
I even tried the latest kernels since 3.10-rc4. (latest I tried is -rc7)

Basically this device *should* work with the 8192cu driver, but it just 
won't.
If you just plug it in, nothing happens.
You have to first:
$ modprobe 8192cu
$ echo 2357 0100 > /sys/bus/usb/drivers/rtl8192cu/new_id

Then it lights up, it shows up in NM-Applet. But it won't work.
I tried enabling the realtek debug option at the kernel driver, but it 
didn't help.
Even with that, I only see the authentication failed messages.

Dmesg shows the errors: http://pastebin.com/QCfXYCZ1


Hope you guys can come up with some tips/ideas.
Ps.: I hope you don't mind the CC Larry.

Best regards,

In the future, I will refuse to answer your e-mails regarding wireless devices
*UNLESS* you also Cc a wireless mailing list. The "best" option would be
linux-wireless@vger.kernel.org. If you have any questions about why I insist on
this, please read the following two links as to why emailing a single person
directly is usually not a good thing, and causes extra work on a single person:
     http://www.arm.linux.org.uk/news/?newsitem=11
     http://www.eyrie.org/~eagle/faqs/questions.html

I cannot add you to the list as that would expose your email address on a public
forum, and I will not create a second breach of etiquette just because you
already did one.

Your device is *NOT* an RTL8192CU device. I wondered when I saw the 300 Mbps,
but I was certain when I saw it was a dual-band device.

I have a driver for your device, but I will not tell you how to get it until you
place a proper request on some mailing list!

No, that is what I told you to do.

A patch has been submitted to add that device to the USB_DEVICE table. It is 
included in the wireless-testing git tree, but it is not in the mainline code 
(yet). After that patch was applied, the device worked for that reported.

I noticed that you are getting an oops from iwlwifi, and an ehci-hcd error. Are 
you also exploring these problems?

If possible, could you use the wireless-testing repo? That will get you the 
latest code for all wireless drivers, and the USB code will match mainline.

Larry

Re: Fwd: Re: TP-Link 8200ND - rtl8192cu module not loading / working

[shiki.biomernok]

Hello Larry/Mailing list!

I have compiled and installed the new wireless-testing kernel from git.
I'm sure I used the new kernel, as the device lighted up as soon as I 
plugged in. (And I got some new atheros ac module at "make oldconfig".)
There was no need for manual echo or modprobe.

Yet, the device is not working. It dies at the very same step.
Here is the dmesg: http://pastebin.com/C1MNdFiw

Please, let me know if I can help with anything.
Any debug option, patch or things like that.

My offer is still there Larry, I'm willing to give you a full SSH access 
to the machine with this stuff plugged in.
Besides that, I have no other idea.


! My router runs OpenWRT (latest stable), so I could also gather info 
from there. If it's possible.
(I checked dmesg but there is nothing. Only some non-crucial info about 
the generic eth ports and such.)

Thank you for the help.

(By the way if the chip is rare (no other people will benefit), then I 
can just get it back and ask for a refund. But if others use it as well, 
then it's not a waste of time... I guess.)

I think the TP-Link 8200ND is relatively new. You have version 0x11 for your 
chip, and mine is 0x10. That could be a difference.

Whay are you forcing the module loading? As indicated by the (F) in the 
traceback, it looks as if all of them are being forced.

Re: Fwd: Re: TP-Link 8200ND - rtl8192cu module not loading / working

[shiki.biomernok]

I have tried to patch my driver but it wouldn't work.
Sent only Larry a message, because I couldn't figure it out why it 
wouldn't work.

Only now I realized that I didn't patch the uncompressed driver itself, 
but this whole "package".
(Sorry when I tried it yesterday, it was already kinda late.)

I also sent him answers about the questions he asked:
- Forced module loading: I use Xubuntu with my own kernel config. (See: 
http://pastebin.com/MR0FHS9w)
- Iwlwifi problem: I did have kernel panic with -rc4, but it's gone 
since -rc6.
(Though I didn't test it that thorough.)

@Xose: What does that mean for me? Am I trying the wrong driver?

By the way guys... how will the closed-source driver help with the 
open-source one?
I mean, I'm sure it will work/load for the device. But people been 
complaining about it.
Thought I could help to fix it up for this specific chip.
(I curse the guy who said this will work under Linux. Argl.)

The closed source driver is not working either.
It compiled like a charm, and it loads perfectly.
(I even blacklisted the open-source one!)

But there is nothing in iwconfig or ifconfig.
Here is the dmesg: http://pastebin.com/EX8h1HfZ

I really don't want to waste your time guys by the way. If there is no 
way to fix it, let's just leave it. (Don't get me wrong I know things 
can be troublesome on Linux and I'm still willing to try anything. I 
just bet you have better things to do. :))

No, that should be the correct driver.
But it looks like rtl8192cu wasn't tested enough with 2T2R(RTL8192CUS)
devices.

The code in wireless-testing works fine on my Edimax EW-7811Un, which reports as 
an RTL8192CUS. If someone wants to send me an 8200ND, I'll make it work. Note: 
Realtek does not supply me with samples of USB devices.

The standard Realtek driver does not have the 8200ND in its device table. Apply 
the attached patch to add the necessary code. This patch was made for the driver 
version that I just sent you privately, but it should work on the other version. 
Please test both with this patch.

Thanks,

Larry

Hello!

So I already wanted to write a letter about how the new driver won't do 
anything. Then I got Larry's message and applied the patch immediately.

- The device starts up with no led activity (it should blink (slow) if 
plugged in)
^This is an annoying "feature", but... yeah.

- LED goes off if you disconnect. (Actually I like this behavior a lot 
more.)

- With this driver, I can actually connect and get a password wrong 
dialog. (it's correct.) So I suppose it's the same thing.. auth failed, 
just now I have my proper Nm-applet dialog, asking for a new password. 
(Oh, and finally this driver shows activity in the tray, as in, you can 
see it tries to connect. You know, that green orb going around. But only 
one of them is green and you will get prompted for a new password.)

Here is the dmesg (hope it helps.):
http://pastebin.com/uUsp7edb

I tried to compile the Linus git version of the kernel, but it comes 
with an even older wireless code than the "wireless-next" one. (Well, 
obviously, but you know.)

Could I go more verbose somehow?
Maybe with THIS driver? Or somehow fiddle with my router?

Ps.: That  really sucks Larry. I mean, you are the wireless wizard for 
Realtek and you don't get devices? Just what the... why? All of my why, 
man...

The dmesg output shows that the device authenticated and associated. If you 
still got a password problem after that, then the device is not able to actually 
transmit data.

Of course. Wireless-next has the code that will be in 3.11. I think I told you 
to use wireless-testing, which is the tree I use. It is essentially 3.10 with a 
few changes that are in the pipeline.

> Could I go more verbose somehow?

You could change the line in core/debug.c that says "u32 GlobalDebugLevel = 
_drv_info_". The symbol _drv_info_ has value 7, and you could try values down to 
1; however, I am not prepared to spend a lot of time looking at such dumps.

A better approach would be to use a different computer and wireshark to capture 
the "in the air" traffic between the 8200ND and the AP.

I get all PCI devices, which is why their drivers are in better shape.

But Edimax EW-7811Un is a 1T1R device.

Just like the other driver, it authenticated and associated. I guess it never 
got the IP address.

I just sent it to you due to the size of the driver, and the fact that it was 
not released. I put this one back on the list.

I just ordered an 8200ND through E-Bay. I'll let you know what I find when it 
arrives.
