No wireless support for Realtek RTL8192EE [10ec:818b]

[Adam Lee]

Open this bug to trace device driver RTL8192EE.

We have seen this wireless card on some laptops, id is [10ec:818b], driver is RTL8192EE.

This bug is only for the initial support of this WiFi adapter, it's not working 100% well yet, please report new "not working bug" or contact upstream but not keep posting comments, thanks.

Status:

pull-request for trusty was NAKed because next minor Trusty release will use Utopic LTS kernel, which had already fixed this issue.

please wait it or upgrade your whole distro to Utopic.

[Adam Lee (adam8157)]

Set to incomplete, waiting the driver shows up in mainline.

[Adam Lee (adam8157)]

still not in wireless-next by now.

[Sascha Grossenbacher (berdir)]

I have this card in a new Thinkpad T440s.

[Elliott Conant (elliottcon)]

Similarly, I have this in a Thinkpad T540p.

[Yvon Xiao (yvonxiao)]

I also have this card in Thinkpad T440p

[William Oprandi (woprandi)]

Same for T440s

[K Xu (kx-anticss)]

Also have this problem.

[Naohiro hayashi (n-hayashi1134)]

I have this problem in Thinkpad T440p

[caobenzhi (caobenzhi0915)]

I have the same problem in Thinkpad T440.

[German (gergilar)]

I have the same problem in Thinkpad L440

[Xprogrammer (programmer-x)]

I've same problem with my t440s.

[K Xu (kx-anticss)]

Any thoughts on when this will be fixed?

[Adam Lee (adam8157)]

we are working on a solution now.

[Xprogrammer (programmer-x)]

After continous search for RTL8192EE driver, I found it here.

http://netbook-remix.archive.canonical.com/updates/pool/public/o/oem-wireless-rtl-92ce-92se-92de-8723ae-88ee-8723be-92ee-dkms/

I'm able to compile and load rtl8192ee on my lenovo t440s laptop.

However, transmitt speed very slow. For couple of times I got too many Invalid misc: and practically the connection is useless.

After few reboots and it seems to be fine. I'm sending this note from t440s loaded with 8192ee internet connection. Main drawback right now, I'm able to get only at max 60kB/s.

[Jody McIntyre (scjody)]

I was able to build and install the driver Xprogrammer found, but it does not work for me at all. It can get an address via DHCP but after that I can't even ping the default gateway.

There were several warnings produced during the build, lots of dmesg output, and a stack dump triggered in net/mac80211/rate.c:518 (a comment in rate.c indicates "RC is busted".

I can send along all of that if it's useful to anyone, but unless you have access to hardware documentation I doubt you'll be able to fix the driver. Based on the volume of the dmesg output, it appears to be an internal or alpha driver that escaped rather than something that's intended for production. I will contact the driver authors to see if they have a newer version (the version Xprogrammer found dates from October 22).

This commit is made in to firmware mainstream branch. Would that help ? However I don't see source code, it has put only the firmware files.

[Adam Lee (adam8157)]

Realtek hasn't officially released the driver in website or kernel mainline yet.

[Abe Handler (akh2103)]

I am also having trouble with this wireless card on 12.04

[wapingguo (wapingguo)]

My laptop is Lenovo ThinkPad T440p,I have the same problem on Ubuntu 12.04.
I found the device is 2x2 11b/g/n wireless M.2 adapter.

[Xiaojun Chen (xiaojunch)]

Yes, I have the same problem.

My laptop is T440s, and the wireless card is the same one, Realtek RTL8192EE [10ec:818b].

Look forward to solutions!

[[e-mail] (mingkedu)]

I've been waiting this for almost a month, really need the driver

[Siu On Chan (sochan)]

The problem may go away starting kernel 3.14. See comments #16 in
https://bbs.archlinux.org/viewtopic.php?id=174082

Haven't tested it myself, but I'm optimistic.

[William Oprandi (woprandi)]

Does someone has succeeded to build and run the staging driver ?

[Vipin (v-rathor)]

Guys,
Just sharing my experience with this issue.
I've got Lenovo Thinkpad L440 recently which has this realtek network device. Installed 12.04 LTS and all I could see was "no network device available". So no wired & wireless connection could be made. Then I read various solutions over web and then found this bug filed.
Later I tried installing 3.14-rc7 and rebooted. Now my wired connection (ethX) is up but still no wireless support. Now I see only one UNCLAIMED (earlier there were 2) h/w in 'lshw' output.

[Adam Lee (adam8157)]

For the record, I analyzed the code, that RTL8821AE driver only supports 8812 and 8821, pci ids in headfile means nothing. RTL8192EE has not been upstreamed yet.

rtl8821ae/sw.c
420: {RTL_PCI_DEVICE(PCI_VENDOR_ID_REALTEK, 0x8812, rtl8821ae_hal_cfg)},
421: {RTL_PCI_DEVICE(PCI_VENDOR_ID_REALTEK, 0x8821, rtl8821ae_hal_cfg)},
426: {RTL_PCI_DEVICE(PCI_VENDOR_ID_REALTEK, 0x8812, rtl8821ae_hal_cfg)},
427: {RTL_PCI_DEVICE(PCI_VENDOR_ID_REALTEK, 0x8821, rtl8821ae_hal_cfg)},

[Bruce D'Arcus (bdarcus)]

So we're waiting on Realtek to release the driver, with no ETA?

Just got a Thinkpad T440s, and bummed to see no wireless.

[Mike McNally (emmecinque)]

Also built the oem-rtl-etc. driver on 13.10 for a T440p; module loads and looks like it connects to a hub, and *sometimes* some traffic makes it through, but it basically doesn't work.

[Josh Arenson (josharenson)]

Why is this part Ubuntu certified (http://www.ubuntu.com/certification/catalog/component/pci/10ec%3A818b/) if it doesn't work at all?

[Adam Lee (adam8157)]

@Josh, our preload image contains out-of-kernel-tree driver, which is provided by realtek.

[Vipin (v-rathor)]

@Adam, may I know where can I get the driver you are talking about? preload images?
Pardon my orientataion, can you please point me in right direction? Thanks.

[Bruce D'Arcus (bdarcus)]

FWIW, I'm using (x)ubuntu.

[Sharon Talbot (sharon-talbot)]

As a point of policy, it may not make sense to utilize images that are not available to the general public, or that are older than the most recent LTE release.

[Adam Lee (adam8157)]

This is the driver package we used in OEM preload image.

Please notice, the source is from RealTek, canonical has no ability to provide support(debugging or fixing). If you are not using OEM preload image and this driver is not working, please contact RealTek. Thanks.

[Bruce D'Arcus (bdarcus)]

@Adam - thanks. I get an error when trying to install the package, so
am contacting Realtek.

[Adam Lee (adam8157)]

This is the original driver source tarball from RealTek. You can try this one if there are some issues while installing that deb package.

Same situation, please notice that Ubuntu couldn't do anything with this tarball's issues before it's upstreamed by RealTek. Thanks.

[Larry Finger (larry-finger-lwfinger)]

Unless you post the console traceback when the system freezes, how can we tell if it is the driver?

If you can reliable force the freeze with a particular command, put a "sleep 5; " before that command. During that 5 seconds delay, switch to the logging console (CTRL/ALT/F10 on my system). When the system freezes, there should be a display on the screen. Take a picture and post it.

[Larry Finger (larry-finger-lwfinger)]

This morning, a bug was found that could cause an oops on the RTL8192EE. All branches of the repo have been fixed.

[Ivan Alejandro (ivanalejandro0)]

cool, I've updated the troy branch and installed the new kernel module.

I'm still having the connection on&off issue, some pings over 2000ms as well like before.
The system freeze happens on module reload so I'll make some time to try to reproduce the problem and post an image.

[Ivan Alejandro (ivanalejandro0)]

Here is a dmesg log that has a traceback.
Is the result of a clean power on, suspend and resume.
I didn't have a freeze this time but maybe the problem is related to this.

[Larry Finger (larry-finger-lwfinger)]

Something is messed up. Those dmesg outputs are not coming from the driver in the rtlwifi_new repo. What other drivers have you installed?

[Krzysztof Janowicz (janowicz)]

Still the same, despite a new kernel (3.19) running on 14.10. Essentially, Lenovo T440(s) and T540 don't have wifi on Linux.

[Larry Finger (larry-finger-lwfinger)]

That is the early adopter's problem. For me, any branch of the rtlwifi_new git repo, or the kernel work. Are you sure it is not a problem with Ubuntu user space?

[Simon Déziel (sdeziel)]

Users of Trusty should give a try to the HWE kernel (3.16 ATM) that is officially supported.

For details on how to enable this: https://wiki.ubuntu.com/Kernel/LTSEnablementStack

[William Oprandi (woprandi)]

I'm using Fedora with kernel 3.19.3 (which use the latest rtlwifi_new if I well understood) but I'm unable to use wifi, I can connect to an access point (sometimes with difficulty) but unable to surf without wait a (very) long time to load a web page. I was forced to use a ethernet wire just to go here to write this comment.... Since end of 2013 we're waiting a decent driver (just stable to surf correctly) and still not...

[Damian Nadales (dnadales)]

@Simon: I tried with kernel 3.16 in Utopic with the drivers shipped with the kernel, and the wireless works quite bad (very low speeds, pages take several minutes to load). Won't Trusty users experience the same?

[Adam Lee (adam8157)]

@Damian, please report a new bug.

This bug is only for the initial support of this WiFi adapter, it's not working 100% well yet, please report new "not working bug" or contact upstream but not keep posting comments, thanks.

BTW, if anyone's case is Larry's github version works well but Ubuntu built-in doesn't, please report here with the realtek section in the output of `lspci -vvv`, thanks.

[Ivan Alejandro (ivanalejandro0)]

Hello again, I just installed the linux kernel 4.0 in my Thinkpad L440 and I'm still having the delayed pings and on&off connection problem. Should I install the driver from the rtl_wifi repo?
@larry, you asked about the weird dmesg to me or to Hanson.diao?

How can I figure out if the problem is the Ubuntu user space?
Is there any other information I can give you or any other test that I can do to figure out where the problem may be?

[Damian Nadales (dnadales)]

@Adam: you're right. I didn't realize that. Sorry for the spam. I'll take the issues to the places you proposed.

Driver r8192ee is from the staging directory for kernels older than 3.18. It is *not* the one in rtlwifi_new. You need to blacklist r8192ee!

[Lee Zamparo (zamparo)]

Indeed you’re right; my apologies for confusing the issue.

Dear Larry and other troubled souls,

Thank you very much for your efforts in getting this working. I can happily report that finally this seems to be working smoothly on an L440, with Trusty and 3.18 Kernel, r8192 blacklisted. Here are some log files for info.

[Lee Zamparo (zamparo)]

I'd like to echo #356, the QOS of this card is pretty good now over WPA2 connections, thanks so much @lwfinger and the Realtek engineers for all your hard work.

I must also echo the concerns of #193 (@dreamcontrol8000), and state that I'm not able to connect to 802.11x networks that use PEAP/MSCHAPv2 authentication. Maybe this is asking too much, since most users don't have to authenticate under this protocol. I imagine it's difficult to test, given the substantial work to create a test environment that operates under PEAP. But I'll log this anyhow, since it's an issue for me.

[Lee Zamparo (zamparo)]

Sigh. Scratch #357, it was down to a detection issue by network-manager trying Tunneled TLS rather than PEAP. After correcting that, I'm able to connect first try just fine. So, thanks once again for all your diligent work.

[Larry Finger (larry-finger-lwfinger)]

I certainly do not have the test environment to test 802.11x networks. I tried once to implement a radius server to check WPA2 Enterprise, and was never able to get it going.

That said, from the driver's standpoint, it is just passing packets and should not care how the AP is getting its authentication. If you are able to capture the over-the-air packets during the authentication process, or detailed logs from the AP or authentication server, then we might be able to find out what is going wrong

[Feer (r-feer)]

Good evening

I am an owner of a T440 with a rtl card. I had to wait a long time for
Wifi as a simple user. I was a listener to your blog. With your
publication how to install I have now a working cableless internet
connection, stable.
I wish to express you my thanks.

kind regards

[Aaron Landesman (aaronlandesman)]

Hi,

After running the commands listed in #352, I still have no wifi connectivity. (Network Manager shows SSIDs but won't connect to any of them.)

There is relevant output from dmesg:

[ 6.651450] rtl8192ee:_rtl92ee_fw_free_to_go():<0-0> chksum report faill ! REG_MCUFWDL:0x00070600 .
[ 6.651454] rtl8192ee:rtl92ee_download_fw():<0-0> Firmware is not ready to run!

Does anyone have any advice how to fix what's causing these errors?

Thanks.

[Larry Finger (larry-finger-lwfinger)]

Is the firmware installed? What is the output of the command 'ls /lib/firmware/rtlwifi/*'?

[Aaron Landesman (aaronlandesman)]

I'm not certain how to tell whether it's installed, but the output of the command is

[Larry Finger (larry-finger-lwfinger)]

You have the firmware. Perhaps you have wireless disabled with some switch.

What does 'rfkill list all' show?

[Aaron Landesman (aaronlandesman)]

rfkill list all shows:

[Larry Finger (larry-finger-lwfinger)]

I have no idea what your problem is. When I reboot with the RTL8192EE installed, it connects quickly to one of my APs.

The output of 'dmesg | grep rtl' is

[ 10.146821] rtl8192ee: Using firmware rtlwifi/rtl8192eefw.bin

The last line is because it connected with an 802.11g AP.. To check your firmware, the command 'md5sum /lib/firmware/rtlwifi/rtl8192eefw.bin' should return

c8ced945fe922aa0cdff91f40a77bf12 /lib/firmware/rtlwifi/rtl8192eefw.bin

I get the same results for either the 4.5-rc5 kernel from wireless-drivers-next or the drivers from the rtlwifi_new GitHub repo.

[Aaron Landesman (aaronlandesman)]

When I run your second command md5sum /lib/firmware/rtlwifi/rtl8192eefw.bin, I get what you say. But, when I run your first command, I get a really long string of errors which all look the same:

I am experiencing the same problem as aaronlandesman on a Lenovo x240 running Ubuntu 16.04, kernel 4.4.0-24-generic.

[Ventusfahrer (ventusfahrer)]

Still the same problem on Lenovo T440 on Ubuntu 18.04 AND Ubuntu 18.10.

'Init MAC failed' all the time

[Larry Finger (larry-finger-lwfinger)]

None of my hardware can duplicate this problem. Is the firmware installed? Look at the dmesg output to look for firmware failures.

If you do have the correct firmware, there are two options that might help. Try the following:

sudo modprobe -rv rtl8192ee
sudo modprobe -v rtl8192ee aspm=0

If that does not help, then try

sudo modprobe -rv rtl8192ee
sudo modprobe -v rtl8192ee msi=0

If any other options show up, then your /etc/modprobe.d/ directory is screwed up. Delete the offending files and try again.

If one of those options helps, then create /etc/modprobe.d/50-rtl8192ee.conf (as root), and add the single line containing "options rtl8192ee xxxx=0" where xxxx is the option you want to set.

[Ventusfahrer (ventusfahrer)]

well, meanwhile I installed Fedora 29 on this box in order to find out whether the rtl8192ee will work there - no chance. I am posting the output of various commands based on fedora 29 in the attachment 8192.logs.
Well I know it is Fedora 29, if you need an output based on a current Ubuntu or Kubuntu installation, please let me know, I will retest and document the logs on one of these versions.

Thank you very much for any help!

[Larry Finger (larry-finger-lwfinger)]

I reached my contact at Realtek. He analyzed the output and thinks that this particular chip has a faulty EFUSE programming, or that it possible was not programmed in the factory. Either case should have been caught in testing, but mistakes happen.

Has this card been tested on Windows 10?

[Josh Arenson (josharenson)]

Ah, sorry. I swapped this card for an Intel one years ago. I had never
tried the Realtek card on windows either.

Thanks anyway for following up,

I made a Windows 7 partition a few years ago and the Realtek card did not work on Windows 7. I'm not sure about Windows 10, though.

[timarmstrong (tim-g-armstrong)]

The card worked reliably for me on windows 8. I solved my problem by buying
a new laptop with an Intel card and giving the old laptop to my
mother-in-law to use for windows.

If anyone still has this problem, and the card, please run the command 'lspci'. Find the line that describes the RTL8192EE and note the first column, which will be something like "04:00.0". This is the bus and number for the device. Then run 'sudo lspci -s nn:mm -xxxx', where hh:mm is replaced by the bus and number string noted above. Post the output of the last command.
