Create a file /etc/modprobe.d/blacklist-r8192e_pci.conf and put

Code: Select all

blacklist r8192e_pci
in it. Then reboot and see what happens. If this doesn't help, delete this file and try with a /etc/modprobe.d/blacklist-rtl8192se.conf that contains:

Code: Select all

blacklist rtl8192se
Also check and probably post the output of 'dmesg' in both cases.

Created a file /etc/modprobe.d/blacklist-r8192e_pci.conf containing "blacklist r8192e_pci".
Rebooted.

There seems to be no change.

Deleted a file /etc/modprobe.d/blacklist-r8192e_pci.conf".
Created a file /etc/modprobe.d/blacklist-rtl8192se.conf containing "blacklist rtl8192se".
Rebooted.

There seems to be no change, either.

dmesg output is too long to post.

Hi,
# lsmod | grep 8192
rtl8192se 75756 0
rtl_pci 30938 1 rtl8192se
rtlwifi 84374 2 rtl_pci,rtl8192se
mac80211 718956 3 rtl_pci,rtlwifi,rtl8192se
r8192e_pci 205594 0
rtllib 151690 1 r8192e_pci
In my looking into driver tree, r8192e_pci is staging driver. so, I think you should only rtl8192se driver. it is legal driver. Maybe, kernel would be built with staging driver, so, it would be included in the kernel module also.

But, I am not sure r8192se would work because I have not tried. you can unload rtl8192e_pci and try again.

For staging driver, please refer following link.

I have unloaded r8192e_pci.
Device enp3s0 TYPE:ethernet disappeared, but wifi device did not appear.

Unload them both, then load the se one again

In a temporarily way, you can backup kernel modules relate with rtl8182e_pci to somewhere not to probe them in the boot process.

Then, Try to reboot. I think it is worth try.

P.S : If it would be done in the initramfs, probably, you will regenerate initramfs removing drivers relate with rtl8182_pci.

Same result. No wifi device is found.
