I am currently trying to install the Driver from https://github.com/lwfinger/rtl8188eu.git I tried it with the dkms installation via:

git clone https://github.com/lwfinger/rtl8188eu.git
sudo dkms add ./rtl8188eu
sudo dkms install 8188eu/1.0
sudo modprobe 8188eu

Did not work, so i removed the driver from dkms. After that i tried this:

git clone https://github.com/lwfinger/rtl8188eu.git
cd rtl8188eu
make all
sudo make install
sudo reboot

Output: $ lsusb

Both Versions executed with no errors. But the TPLink can not be determined by Xubuntu. I am installing on a new Xubuntu installation.

This does not work for me: How to install driver for TP-Link TL-WN722N(EU)V2 on Ubuntu 17.04 Kylin

What i am doing wrong? EDIT: I added some output information.

EDIT: Added more output information. lsmod | grep 8188

8188eu 720896 0

dmesg | grep 8188 [ 3.413516] 8188eu: loading out-of-tree module taints kernel. [ 3.413748] 8188eu: module verification failed: signature and/or required key missing - tainting kernel [ 3.414812] Chip Version Info: CHIP_8188E_Normal_Chip_TSMC_D_CUT_1T1R_RomVer(0) [ 3.436788] usbcore: registered new interface driver r8188eu [ 3.438585] r8188eu 3-10:1.0 wlxc025e919795e: renamed from wlan0

edit: I tried that:

sudo ifconfig wlxc025e919795e up

to enable that wlan. Very Strange name by the way. But this must be my wlanusb device. After that i scanned the network and found my accespoints: sudo iwlist wlxc025e919795e scan gives me the available access points. Then i connect to one accces point by the hardware adress of the accespoint: sudo iwconfig wlxc025e919795e ap AA:BB:CC:DD:EE:FF key off after that. i execute ifconfig. and i get an ipv6 adress. I also would get an ipv4 adress. On my apple macbook i get an ipv4 and a ipv6 adress from the router. My Networkmanager shows me that i have still no internet connection. But i can ping the router with ping6. ping6 -I wlxc025e919795e fe80::c225:and:the:rest:of:the:ipv6:adress

The router responds and i get a signal. Iam unable to ping google.com or a other server because iam in an captive portal network from the Telekom. and i have to send an http request from my firefox browser for example to get to the login page. My webserver says that the website is not found. Looks like that firefox thinks that iam not connected to the router. XFCE says that a wlan does not exist. Maybee i have to rename wlxc025e919795e to wlan0 but how? And why is that so complicated and doesn't work?
