RTL8188EUS wireless adapter

I'm trying to install a usb wireless adaptor with the RTL8188EUS chipset. It comes with a Linux driver for kernels up to 3.19.3, but I'm running 4.4.118 (Slackware 14.2). The install.sh script provided fails to compile the module so I installed the one from Slackbuilds.

The device is recognised:

Code:

dmesg:

[12482.428063] usb 1-10: new high-speed USB device number 12 using xhci_hcd

[12482.592806] usb 1-10: New USB device found, idVendor=0bda, idProduct=818b

lsusb:

No module is loaded when I plug it in, so I load it manually but I've no idea what to do next as no interface shows up:

Code:

 iwconfig

ppp0      no wireless extensions.



lo        no wireless extensions.



eth0      no wireless extensions.



usb0      no wireless extensions.

Code:

ifconfig -a

Any help much appreciated.

In an ideal world, you would hope that device would be supported OOTB by the r8188eu kernel module.

I would suggest trying the latest stand-alone rtl8188eu at https://github.com/lwfinger/rtl8188eu If you have problems, they probably want your feedback.

I tried that, with the same results, except that, on loading the module, cfg80211 and rfkill are also loaded. I also tried the other possibility you mention, with the same results as the Slackbuilds module.
I realised long ago that the only ideal world is this one; ideal but not perfect.
Cheers.

this is how i solved my problems on Slackware 14.2:

https://slackalaxy.com/2017/09/02/tp...wn722n-driver/

I followed solarfields's instructions, but still no wlan0.

you have the linux kernel source, right? any errors?

I have the kernel source, yes. There were no errors with the compilation and install using rtl8188EUS_linux_v4.3.0.8_13968.20150417-target-kernel_4.4, so long as I did:

Code:

modprobe lib80211 cfg80211

before

Code:

insmod /lib/modules/4.9.0-kali4-amd64/kernel/drivers/net/wireless/8188eu.ko

so you did these:

insmod /lib/modules/$KERNEL_VERSION/kernel/drivers/net/wireless/8188eu.ko
modprobe lib80211
modprobe cfg80211
modprobe 8188eu

??
did you try to reboot?

didn't you say you were running 4.4.118? Where did this come from:
insmod /lib/modules/4.9.0-kali4-amd64/kernel/drivers/net/wireless/8188eu.ko

Quote:

insmod /lib/modules/$KERNEL_VERSION/kernel/drivers/net/wireless/8188eu.ko
modprobe lib80211
modprobe cfg80211
modprobe 8188eu

Yes.

Yes. No modules loaded.

Sorry, my bad. Wrong clipman entry. What I did was (of course):

Code:

insmod /lib/modules/4.4.118-smp/kernel/drivers/net/wireless/8188eu.ko

ok, i don't know then

Thanks, anyway. I'll do some more digging.

I have just built a package using the SlackBuilds.org script with the latest source version from https://github.com/lwfinger/rtl8188eu (rtl8188eu-master.zip) by setting 'VERSION="master" '. This built on my -current system without error. The resulting package contains a kernel module 8188eu.ko, but the output from 'modinfo 8188eu' does not show your device identifiers.

Code:

root:~# modinfo 8188eu

Maybe they need to be added to 8188eu.mod.c in the source code.

0bda:818b is the ID of RTL8192EU chipset, not RTL8188EUS. So, you need this driver.

Great stuff!

I had in fact seen that somewhere and tried it but it made no difference. But the link you provided worked and I now have a wlan0. Thanks a million!

Hello! I have bought a TP-LINK TL-WN725N and no one of the given here sollutions solved my problem. Today i did find this driver
https://github.com/quickreflex/rtl8188eus which is working. The driver is compiled with no error and works bidirectional, e. i. i use it like a router to share internet from the desktop to the phone and other devices.
The only question i see is the change of the wlan number. Every time there is an increment and now it is
