No WLAN: TP-Link TLWN823N - Realtek rtl8192cu

[thorstein]

Hi,

l installed Sparkylinux 5.1 from LIve-Iso:
Linux 4.14.0-2-amd64 #1 SMP Debian 4.14.7-1 (2017-12-22) x86_64 GNU/Linux

WLAN does not work with my TP-Link TLWN823N V.3 WLAN-USB adapter that has a Realtek rtl8192cu. Network scan seams ok, but not connection is established. There is even no lsusb entry. I checked WLAN connctiviy with an older Belkin USB adapter that works fine and shows up with lsusb.

For Debian there is a work around for 3.x kernels that was used also for 4.x kernels according to what can be read:

Code Select Expand

apt-get install --reinstall linux-headers-$(uname -r) linux-headers-generic build-essential dkms git
git clone https://github.com/pvaret/rtl8192cu-fixes.git
dkms add ./rtl8192cu-fixes && dkms install 8192cu/1.10 && depmod -a
cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/
modprobe 8192cu


linux-headers-generic package doesn't come with Sparkylinux. Should I install the linux-headers-4.14.0-2-all-amd64 package instead? Anyone who did this?

Thanks!

OK, I tried it with installin the linux-headers-4.14.0-2-all-amd64 package

Obviously, no errors occured and the connection with the Belkin USB adapter (also rtl8192cu according to lsusb) seems to have even more stable connections now.

But the TP-Link TLWN823N adapter became completly quite, doesn't scan anymore, and still is not listed by lsusb.

Any idea?

Thanks for the link. Seems, the device is not among the known adapters. I'll try to get an older adapter.
