[SOLVED]Wifi !?

Postby creachei » 2018-10-29 14:19

Hello, I've installed debian two days ago, and since then I have tried a lot of different solutions found on internet to fix my issue, without results :/ .
So my problem is that I can't connect on wifi with my laptop, and I could with Windows before.
Anyone could help me ? I would be forever grateful ^^

The first thing is probably read these two pages in the wiki
https://wiki.debian.org/WiFi
https://wiki.debian.org/WiFi/HowToUse

If you've already read them but they didn't help, then adding more details to your post will help other people help you. Please don;t make people drag info out of you, it makes confusing thread.

I'm sorry, I don't really know what I am doing, or what infos are useful to someone who would like to help me.
I have found someone telling to run a 'wireless_script', maybe its output can be useful :

Looks like you need kernel 4.11 or newer:

https://wikidevi.com/wiki/Realtek_RTL87 ... mbo_Module

The kernel version in stretch-backports should support it:

https://backports.debian.org/

I think you will also need the backported firmware-realtek package.
I suffer from depression and may lash out occasionally, try not to take it personally.

Hey, that Ubuntu wireless info script really helps provide information! https://github.com/UbuntuForums/wireless-info

Maybe I'll package it for MX.
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Quod Libet 4.2.0, Pale Moon 28.2.0, wine-staging 3.20, GIMP 2.10.8, Liquorix kernel 4.18-22, Midori 6.0

Ok, Head_on_a_Stick, I did what you suggested, I still can't connect to wifi, but maybe didn't I get the right kernel (or I'm missing something obvious :? ).

Try
Code: Select all
# apt install rfkill
# rfkill unblock all

If it doesn't work then post the output of plain `rfkill`, thanks!

Do you mean "rfkill" ? it's purpose ? you could have looked it up:
https://linux.die.net/man/1/rfkill
unblock index|type
Enable the device corresponding to the given index. If the device is hard-blocked, e.g. via a hardware switch, it will remain unavailable though it is now soft-unblocked.

Since you use "all" , it unblocked them all,...

So if I understand well, rfkill should have enabled my wireless device, but I can't find a proof that it is the case :/
I just tried
Code: Select all
rfkill list wifi
but nothing came out.

It worked,---snip--

Is that not proof enough, ?
There is a lot more about rfkill available:
what is the purpose of rfkill on Debian ?

OK maybe I talked too fast when I said "it worked", and maybe it didn't worked as expected.
I said that because i saw no error output as I used rfkill, but it seems that it did not ... worked.
I'm not sure, but I think the only device recognized as wireless (if it makes sense) is the bluetooth :
Code: Select all
creachei@pc-141:~$ sudo rfkill list
0: hci0: Bluetooth
   Soft blocked: no
   Hard blocked: no


and
Code: Select all
creachei@pc-141:~$ sudo rfkill
Usage:   rfkill [options] command
Options:
   --version   show version (0.5-1+b1 (Debian))
Commands:
   help
   event
   list [IDENTIFIER]
   block IDENTIFIER
   unblock IDENTIFIER
where IDENTIFIER is the index no. of an rfkill switch or one of:
   <idx> all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm nfc
