[SOLVED] wlp3s0 interface does not support scanning

I recently downloaded Arch and I am having trouble connecting to the wifi for the first time.

My network manager is not scanning for available networks. I also used iwlist to scan but it gave me the error Interface doesn't support scanning: Network is down

Some commands I input and there output:

---

 nmcli dev wifi list

Nothing (the list does not show any networks)

---

iwlist wlp3s0 scan

wlp3s0   Interface doesn't support scanning : Network is down

---

lspci -vnn | grep -i net

00:19.0 Ethernet controller [0200]: Intel Corporation Ethernet Connection I218-V [8086:1559] (rev 04)
03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8192EE PCIe Wireless Network Adapter [10ec:818b]

---

nmcli radio wifi

enabled

I tried to update the system or drivers but since there is no wifi or internet connect I cannot update any packages or install any new packages. How can I solve this issue and make the interface scan for wifi networks around me? Let me know if you need more info.

Re: [SOLVED] wlp3s0 interface does not support scanning

Don't use networkmanager and iw in parallel.
Stop networkmanager, post the output of "ip a" and try to connect w/ either wifi-menu (from the netctl package) or manuall, https://wiki.archlinux.org/title/Networ … ireless#iw

Re: [SOLVED] wlp3s0 interface does not support scanning

I tried using iw to connect but it is not working.

---

iw dev

bash: iw:command not found

I don't know why it says that.

Try wifi-menu first, but make sure that the NM service is stopped.

Re: [SOLVED] wlp3s0 interface does not support scanning

I did try with wifi menu. I already did 'ip link set wlp3s0 up' before I ran 'wifi-menu'

sudo wifi-menu

Scanning for networks... Could not set interface wlp3s0 flags (UP): Invalid argument
nl80211: Could not set interface 'wlp3s0' UP
Could not set interface wlp3s0 flags (UP): Invalid argument
WEXT: Could not set interface 'wlp3s0' UP
wlp3s0: Failed to initialize driver interface

Re: [SOLVED] wlp3s0 interface does not support scanning

nl80211: Could not set interface 'wlp3s0' UP

I already did 'ip link set wlp3s0 up' before

wifi-menu will not use NICs that are already up to not interfere w/ other services.
So first put it down again.

Re: [SOLVED] wlp3s0 interface does not support scanning

I used 'ip link set wlp3s0 down' to put it down but it still gives me the same error when I run 'wifi-menu'. Is that what you were talking about?

Re: [SOLVED] wlp3s0 interface does not support scanning

Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'f:1=<-' ix.io

Re: [SOLVED] wlp3s0 interface does not support scanning

sudo journalctl -b | curl -F 'f:1=<-' ix.io

curl: (6) Could bot resolve host:ix.io

Is there any other command I can use? When I use that command it gives me this error

Re: [SOLVED] wlp3s0 interface does not support scanning

You need an internet connection for this, how do you post at the moment?
You can also redirect the output into a file and upload that.

I have another laptop which I am using to post at the moment. I installed arch on my other laptop.

Re: [SOLVED] wlp3s0 interface does not support scanning

sudo journalctl -b | curl -F 'f:1=<-' ix.io

give me an error as an output

Re: [SOLVED] wlp3s0 interface does not support scanning

"sudo journalctl -b" prints the journal, "curl -F 'f:1=<-' ix.io" uploads it and "|" is a pipe.

sudo journalctl -b > /tmp/journal.txt

Re: [SOLVED] wlp3s0 interface does not support scanning

OK, I got the output from 'journalctl -b'. Is there anything I should hide or change for my privacy and safety before uploading it to this forum?

Re: [SOLVED] wlp3s0 interface does not support scanning

If you gave your user a salacious name, that's your problem
But the journal isn't supposed to contain sensitive data.
Be aware that sudo is logged, so if you typed "sudo mpv hamsterporn.mp4", that'll show up.

Re: [SOLVED] wlp3s0 interface does not support scanning

I can repost the text based on any specifications I can look up keywords like network or whatnot and put them all together and post them...just let me know it is a lot of lines and I don't expect you to go through all of it. Sorry about posting the pdf I thought it would be easier but whatever you is easier is fine with me

Re: [SOLVED] wlp3s0 interface does not support scanning

pacman -Qs firmware

https://archlinux.org/packages/core/any/linux-firmware/

You can also use pastebin services, but yes - generally all lines unless specifically askes elsewise.

Re: [SOLVED] wlp3s0 interface does not support scanning

Yeah, I kinda knew that
Install the package I linked.

Edit, inb4: you can download it from the webpage and "pacman -U linux-firmware-123.tar.xyz" it

Re: [SOLVED] wlp3s0 interface does not support scanning

I can't install new packages using pacman because I am not connected to the internet. I am using another Windows laptop that has a Wi-Fi connection, is there a way I can download them on the Windows device and transfer them to the arch device via USB?

Re: [SOLVED] wlp3s0 interface does not support scanning

Sorry about that after posting the comment I realized you already told me I can download it through the webpage. Once I download it, extract it, and transfer it over what directory should I save it in?
