TP-LINK TL-WN823N V2 WiFi adapter

I've been testing this driver for a few days, and I can tell that it works nice with TP-LINK TL-WN823N V2 WiFi adapter . I've got transfer around 170 mbit/s. There's a few problems with replugging/unplugging the device. I always get the following log:

Hi, I am a newbie. I wish you could tell me how to make the wireless adapter work. Regards,

Even though it is a little late, I hope this tutorial will help you and others, especially new users in compiling this driver package, including how to make it work in kernel 4.9.x..

Just copy the url and paste into a new tab or window:

https://scdas141.wordpress.com/2017/01/28/how-to-compile-mangertl8192eu-linux-driver-driver/

The next Ubuntu version will ship with 4.10.x kernel, so I needed the work around from scdas141 to get the driver working. Thanks for the helpfull howto!

i did what scadas141 said with ArchLinux on kernel 4.10 and it didn't worked :/ did the same with KDE Neon on kernel 4.8 and worked

This works absolutely like a charm with TP-LINK TL-WN823N V2 WiFi adapter running on KDE neon 4.9.2 (based on Ubuntu 16 LTS) Kernel 4.8.

Hi guys, I've bought this adapter. After testing upstream new rtl8xxxu driver that locks me at 1MBit/s, I've started using the Realtek one; I've found and pushed a most recent version (v4.4.1), see mirrored Release Notes. Realtek supports linux-4.4.65 longterm, working stable at 130.0 MBit/s. I've patched differently from this repo for linux-4.7 to get compiled.

Hi,

I've downloaded this one: https://github.com/masterzorag/RTL8192EU-linux compiled and installed the folder "rtl8192eu", after restart I'm locked at 1MBit/s upload speed.

Running lsmod I see the "rtl8xxxu" module loaded, so, how can I install and load the Realtek one that had worked for you to unlock the 1MBit/s upload limit?

(my kernel is 4.8.0-49-generic). Thanks

@nomadmzl just

rmmod rtl8xxxu
modprobe 8192eu

Maybe interface name will increment, check dmesg iwconfig if using WEXT, iw wlan0 link if using new CFG80211

Also, linux-4.8.y seems EndOfLine, making linux-4.4.y more updated than it...

@masterzorag

Hi, inside the folder "rtl8192eu" I run "make && make install", so I unload the module rtl8xxxu module with rmmod (succesfully), but when I try to load the 8192eu one I get:

~$ modprobe 8192eu modprobe: FATAL: Module 8192eu not found in directory /lib/modules/4.8.0-49-generic

What I'm doing wrong? I'm using the files in: https://github.com/masterzorag/RTL8192EU-linux

Bye!

You are good, just missing a step. After make install you should depmod -a to get modprobe see the newly installed module; Or, you can insmod the module providing full path; Also, consider building, installing and loading module as root or by sudo.

@nomadmzl, you are running linux-4.8.y that is not officially supported by Realtek driver; We have to patch the code to get it ported and I've patch for linux-4.7; You should move to linux-4.4.y to get it working as it should, use you package manager to get it;

If you want to try my edits for linux-4.7 you have to git checkout linux-4.7 from my repo, then build, install and load since fixes are in a separate branch. Check this one

@masterzorag, @nomadmzl maybe you should continue the discussion on a new issue The compilation problems with 4.8 are not related to this repo Will be more easy to track for future references if someone open a issue directly on https://github.com/masterzorag/RTL8192EU-linux/issues

I have the same adapter TL-WN823N v2

Kernel - 4.9.34-1-lts Arch Linux

The dongle was detected by the default rtl8xxxu module, but the light didn't come on, and I was unable to actually connect to a network.

Using this repo, everything seems to work fine for now. I blacklisted the inbuilt 8xxxu module to force the 8192eu to load.

Initially, I got a lot of journal spam

adding the following to /etc/modprobe.d/8192.conf stopped those

options 8192eu rtw_power_mgnt=0 rtw_enusbss=0

(I don't thing rtl_enusbss=0 is required, because it already defaults to 0)

I do however get some more messages like the following

Not sure how to get rid of them.

Another issue is that iw does not detect the device. It must be a wext/cfg issue. I am connected to the internet, but iw lists no devices.

Thanks for this repo. :)

Fixed on realtek-4.4.x branch as commented by @easysid

I have the same device TL-WN823N v2

I am on Kernel Version 4.18.0. Following is the output of trying to install this driver as a kernel module, the build seems to go through fine, but it fails to update initramfs for some reason (I am a noob at building kernel modules) and rollsback.

Any help would be appreciated.

Hi, I have the device TL-WN823N v2, and I was facing the same problem that everyone is facing with ubuntu 16.04 LTS. After googling, i followed steps on forums and reached Pilot6 page and got the 4.4 driver..which worked great. But after downloading the ubuntu updates, twice my driver broke. This time i searched further and found this link.. and followed the steps. It is working great now ..and with increased performance. The wifi signal shows increased strength network signal is increased too.

I have one query though, in future ..should i download standard updates or not? And since you blocked the 8xxxeu driver ..can this problem reappear? Thanks!

My unbutu details: Linux ubuntu16 4.15.0-43-generic #46~16.04.1-Ubuntu SMP Fri Dec 7 13:30:54 UTC 2018 i686 i686 i686 GNU/Linux

@abhishekdanej This problem can reappear. However, since you are compiling specific drivers for the hardware manually to get it working (and it does work), it would be advisable to disable the standard updates.
