I have installed Ubuntu 13 on my system and I have been using a TP-Link TL-WNB23N USB adapter for my wireless on the WIN8 side... They have drivers up at TP-Link for Win/7/8 but not for Linux. Does anyone have a clue?

  • I don't see my USB devices. Also When I do a system test, for USB it doesn't see my Wireless device. – user193854 Sep 18 '13 at 03:09

  • The best way to add additional information to your question is by editing it, with the edit button. It is better visible that way, and comments are mainly for secondary, temporary purposes. Comments are removed under a variety of circumstances. Anything important to your question should be in the question itself. – Danatela Mar 14 '14 at 02:58

The TL-WN823N WLAN USB stick bases on the Realtek chip set RTL8192CU. You can download the driver from Realtek.

  • The driver rtl8192cu is already included in Ubuntu 13.04. Isn't it loaded? Please check: lsmod and iwconfig – chili555 Sep 18 '13 at 13:44
  • lsmod shows a rtl8192CU, rtlwifi, rtl8192c_common – user193854 Sep 19 '13 at 02:39
  • iwconfig shows etho no wireless extensions, lo no wireless extension., wlan0 IEEE 802bgn ESSID:off/any Mode:Managed Access Point: not-associated TX-Power 20 dBm retry long limit:7 RTS thr=2347 B fragment thr:off Power Mangement:off – user193854 Sep 19 '13 at 02:42
  • My windows side when I boot it uses the chip/network. Ubuntu says I am out of range or refuses to connect. – user193854 Sep 19 '13 at 02:42
  • also the ifconfig -a shows a wlan0 being present, up broadcast multicast MTU:1500 – user193854 Sep 19 '13 at 04:38

    I have found that if I unplug it and move it to another USB slot that it will connect for a short while, but after about 20 minutes or so it will show connected but none of my web apps will connect thru. – user193854 Sep 20 '13 at 19:31

git clone https://github.com/jeremyb31/rtl8192eu-linux-driver
cd rtl8192eu-linux-driver
make
sudo make install

If succeeds, this will create the driver module file 8192eu.ko

If the folder /lib/modules/YLV/kernel/drivers/net/wireless/realtek/8192eu doesn't exist (YLV = Your Linux Version ex: 4.13.30-generic) , create it and place the 8192eu.ko the compilation just created in it. 

# Replace 4.13.30-generic to whatever your version is, find it with:
# uname -r

cd /lib/modules/4.13.30-generic/kernel/drivers/net/wireless/realtek
sudo mkdir 8192eu
sudo cp ~/my-dir-where-i-compiled/8192eu.ko 8192eu

Then test it, unloading the current driver, in my case it was rtl8xxxu:

sudo modprobe -r rtl8xxxu
sudo modprobe 8192eu

Doing this the wifi got with 54Mb and 100/100 quality

If fine, blacklist the old driver, adding a string to /etc/modprobe.d/blacklist-modem.conf

blacklist rtl8xxxu

Adding the module to initrd

Add the name of the module to /etc/initramfs-tools/modules.

8192eu

This will add the module to the initrd file. Update the initrd file 

update-initramfs -u    
reboot
