 |
|
Good evening everyone!
I tried to install Gentoo(first time, totally new on Gentoo, though I used Ubuntu for a while years ago) on a Acer Aspire One D255E, everything seems ok, except for the wireless card, which Gentoo can't find using ifconfig.
Here(sorry for the pictures, maybe I should use the wired connection in order to install a DE, but that'd be a problem for me right now) there are the results of | Code: | ifconfig -a
lspci | grep Wireless
rfkill list |

then, the result of | Code: | | lspci -nnkv | sed -n '/Wireless/,/^$/p' | head -n -1 |
I thought that could be useful to let you see that the kernel loads the wireless card driver

Maybe is some firmware missing?
Thank you guys!
edit: I found out that the result of is

though according to ifconfig is an ehternet device(and it actually works when I use a wired connection)
if I try to use iw in order to connect wlp2s0 to my open wifi, it says connected, but nothing works

HilhilPoly,
Welcome to Gentoo.
How did you set up wpa_supplicant?
That wired works in good. ou have all of the bits for that. You will need them for WiFi too.
WiFi set up is a two step process. First, wpa_supplicant associates and authenticates with your access point. That's the extra wifi steps.
Once thats done your wifi behaves like wired and all the wired tools work to set up the interface.
Your kernel module is ath9k. It does not need any firmware.
dmesg should show the associate and authenticate processes.
Make friends with wgetpaste and pastebin all of dmesg if you prefer.
wgetpaste beats photos because helpers can't copy/paste from photos.

I didn't set up wpa_supplicant. I (clearly, it was stupid) supposed that it was not necessary, since my connection is open(A weird ISP in a student accommodation, the router side is completely blocked). Because of that, I didn't looked at wpa_supplicant, too, I'm doing it right now, but I'm not getting how I configure it.
Thank you for the hint about wgetpaste, that's what I was looking for  |

HilhilPoly,
Open does not always mean unencrypted, when it does, you still need something to set up the radio link.
wpa_supplicant can do it all including the encryption, if its there.
For wep and non encrypted liks, wireless-tools (now deprciated) can get the radio link established but you are going to need proper encryption sooner or later.
Hopefully, sooner.
Making a mistake is not stupid, get used to it. Its a part of the gentoo learning experience. At worst, its ignorance. That can be fixed with education, which is what we try to do here.
To help you help yourself.
Making the same mistake over and over ...

First of all, thank all of you guys.
Then, I was reading this guide
But, I have a doubt about this point | Quote: | It is necessary to have CONFIG_PACKET enabled in the kernel for wpa_supplicant to work. To see if it is enabled on the current kernel, try:
| Code: | root #zgrep CONFIG_PACKET /proc/config.gz
root #grep CONFIG_PACKET /usr/src/linux/.config |
|
Because if I try to launch the first command, I get
| Code: | | gzip: /proc/config.gz: No such file or directory |
with the second one, I get
| Code: | CONFIG_PACKET=y
CONFIG_PACKET_DIAG=y |
I don't know if only the second result is enough to run wpa_supplicant properly. Waiting for your answer, I'll pretend it is so.
edit. It seems it is enough, because I can run wpa_supplicant.
Now, its configuration. If use this as a model | Code: | ctrl_interface=DIR=/var/run/wpa_supplicant
#ap_scan=1
#update_config=1
network={
ssid="YourSSID"
psk="your-secret-key"
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
group=CCMP TKIP
pairwise=CCMP TKIP
priority=5
} |
In my case, it should be something like
| Code: | ctrl_interface=DIR=/var/run/wpa_supplicant
#ap_scan=1
#update_config=1
network={
ssid="ASK4 Wireless"
# psk="your-secret-key"
scan_ssid=1
# proto=RSN
key_mgmt=NONE
# group=CCMP TKIP
# pairwise=CCMP TKIP
priority=5
} |
Is this correct?
edit.2 THAT'S IT
after this configuration, I rebooted and now
works
Now I have to download a DE. I hope plasma is not too much heavy for this laptop.
Thank you guys! |

Probably it's this. Even if it's my first time, I decided to configure the kernel using menuconfig, and I actually had to rebuild it twice already, because I forgot some module(or I didn't know about it). Anyway, I don't remember about this module.
It doesn't seem mandatory to me...do you think I should rebuild the kernel using it? |

I use the config from the current kernel source directory. Right now I do not see any case for a personal PC (not a server enviroment) in which this should be wrong.
But since the option does not really affect anything in the kernel build (size, performance) it is safe to enable the option, but also not to. It is up to you if you need it.
