WiFi not showing after fixing this Boot Failure issue. Also this didn’t help.
The live USB shows wifi option
No such option when booted into system

Network:
Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
vendor: Gigabyte driver: r8169 v: kernel pcie: gen: 1 speed: 2.5 GT/s

TP-Link TL-WN823N v2/v3 [Realtek RTL8192EU] is my WiFi USB device.
Kernel: 5.19.7-arch1-1
Probably because of this:
What does sudo dkms autoinstall show?
sudo dkms autoinstall
Deprecated feature: REMAKE_INITRD
That is the whole output?
Yes
What does dkms status show?
dkms status
rtl8192eu/1.0, 5.19.7-arch1-1, x86_64: installedDeprecated feature: REMAKE_INITRD
(rtl8192eu/1.0 because I updated WiFi driver using that guide & it worked fine till the last time)
Can you show the ouput from this shell-cmd, pls:
ip link
ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

(Do let me know if any of the commands show private details like ip adress or anything private, I’ll post the output as screenshot & blur the private parts)
It shows 2 ethernet devices? But no Wifi? Would that be no. 3 (which is missing)??
2 ethernet? Connected to my android device using USB tethering only.
Yep no wifi detection or even wifi option.
Maybe the Wifi is maskerading as an ethernet.
sudo ip link set enp3s0 up
Then again, pls:
ip link
Edit:
It is already UP but says “no-carrier”.
ip link set enp3s0 up
RTNETLINK answers: Operation not permitted
sudo ip link set enp3s0 up
No output
ip link
same output as before
If ip link remains same, it is a driver-issue.
What does ip link give now? Same as before?
yes

you have one of them installed all together?
I do not think device is showing up at all from the output posted here…
from the 4 TP link USB wifi dongles I have here none needs a special drive installed but all showing up as wlan0 running ip link

As I mentioned here, it’s an outdated Driver & I’m using the official driver. I dont have any hope but could try the outdated driver though.
it is a driver-issue.
Could it be the Kernel issue? cause I faced no such issues before.
Two ways to go, and to decide which one first:
Try linux-lts kernel, or try fixing the driver issue first.
Show me the exact driver you have installed, please:
hwinfo --netcard --bluetooth | grep -Ei "(speed|hotplug|model|status|cmd|file|detected|driver:)" | grep -v "Config S"
you have one of them installed all together?
Not using from AUR. Updated from the easylinuxtipsproject guide.
