WiFi Button

Hi, I am a fairly new arch user and I really love it I. I have been able to solve all of my problems so far but this one. I have spent too much time trying to figure out and now I am here. I have a strange problem with the Intel WiFi card on my old acer travel Mate 4060. I have a WiFi button on the front of my laptop that is not working properly. When I boot from the installation media I can press the button, it lights up and when I type

iw dev

I can see my wireless card and connect to a network. If I don't press the button

iw dev

returns nothing and when I try

ip link set wlp6s4 up

I get an rfkill error telling me that the device is blocked. The problem I am having is when I boot to the installation on my HDD. The WiFI button no longer works and I can't see my wireless device using

iw dev

I apologize in advance if this is a stupid question because I am new to arch and I am sorry for the format because this is the first time I ever posted on a forum.

Thank you for your time,

~~~~Reno

Re: WiFi Button

What is the ideal end result?  Do you want it to work like it did with the installation media, or would you prefer that wifi is allowed by default without having to hit the button?

In either case, the first steps will be to install rfkill, and read the wiki page about it.

EDIT: sorry, it seems there is no dedicated rfkill wiki page - but it can be found via the search function on other pages.

Re: WiFi Button

I would like it to be enabled by default.

EDIT: I already installed rfkill and ran

#rfkill list all

and

#rfkill list wifi

both resulted in nothing.

Re: WiFi Button

Install rfkill, then verify that `rfkill unblock all` will allow you to connect.

If it does, then you'll probably want to use the systemd service by enabling rfkill-unblock@all.service (or replace all with you interface name*).

If unblocking doesn't work, then post the results of `rkfill list`

EDIT: This may not be your interface name.  I don't use this service myself, but it looks like it'd be the rfkill IDENTIFIER name (phy0 is common).

Re: WiFi Button

I just saw your edit.  Those resulted in nothing?  Actually nothing, or nothing useful?  Did you just get a clean prompt with no other output at all?

EDIT: crap, sorry, I may have mislead you - partially.  I suspect you will need rfkill, but there's a more basic step missing.  I missed in your initial post that `iw dev` doesn't even show your device.  So we need to start there.

Can you post the output of the following commands:

ip a
lspci -vnn | grep -i net

Re: WiFi Button

[root@reno reno]# rfkill unblock all
[root@reno reno]# iw dev
[root@reno reno]# rfkill list  
[root@reno reno]# rfkill list all
[root@reno reno]# ip link set wlp6s4 up
Cannot find device "wlp6s4"

This is the results.

Re: WiFi Button

Note that your wireless is not shown.  Did you install the firmware in accordance with the wiki?
