WN823N v2 not loaded as network device on Ubuntu 18.04 server

[theflashpack]

I've installed the driver as per the instructions and all seemed to go well: $ dkms status rtl8192eu, 1.0, 4.15.0-76-generic, x86_64: installed

But on boot or USB insertion the device doesn't come up under lshw -c network or ip a

Prior to install it was loading the rtl8xxxu driver, now there isn't any listing.

lsusb shows the device but no device name:

$ lsusb

when I plug in the device dmesg only gives

Is there something else I can do to check what's happening? I looked at changing the log level but there's nothing for rtl* under /proc/net

[CGarces]

So I assume that the module not is loaded.... Try sudo lshw -c network and lsmod If not is loaded, try to load it manually with modprobe. If fails loading the module should give you and error to investigate it.

[theflashpack]

It seems I installed against a kernel that was replaced on reboot

At install earlier today:

$ sudo dkms install rtl8192eu/1.0

Kernel preparation unnecessary for this kernel.  Skipping...

Building module:
cleaning build area...
'make' all KVER=4.15.0-76-generic.........................
cleaning build area...

DKMS: build completed.

8192eu.ko:
Running module version sanity check.
 - Original module
   - No original module exists within this kernel
 - Installation
   - Installing to /lib/modules/4.15.0-76-generic/updates/dkms/

depmod...

Backing up initrd.img-4.15.0-76-generic to /boot/initrd.img-4.15.0-76-generic.old-dkms
Making new initrd.img-4.15.0-76-generic
(If next boot fails, revert to initrd.img-4.15.0-76-generic.old-dkms image)
update-initramfs.......

DKMS: install completed.

but I'm now on

$ uname -a
Linux kiosk1 4.15.0-88-generic #88-Ubuntu SMP Tue Feb 11 20:11:34 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

I did sudo dkms add . but the new kernel might have already been built and waiting for reboot?

Anyway I've re-installed and rebooted and it's all working
