Hello,

I just installed Gentoo on my Samsung RV520 laptop which has an Intel Centrino Wireless N 130 chip:

Code:

01:00.0 Network controller: Intel Corporation Centrino Wireless-N 130 (rev 34)
Subsystem: Intel Corporation Centrino Wireless-N 130 BGN
Flags: bus master, fast devsel, latency 0, IRQ 44
Memory at f0500000 (64-bit, non-prefetchable) [size=8K]
Capabilities: [c8] Power Management version 3
Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
Capabilities: [e0] Express Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting
Capabilities: [140] Device Serial Number b8-03-05-ff-ff-7a-cb-32
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi

However, when I did iwconfig, I didn't get a wlan0 interface. I ran

Code:

# dmesg | grep iwlwifi

and discovered that I didn't have firmware installed. So I found a similar thread describing this problem:
https://forums.gentoo.org/viewtopic-t-925694.html

I followed the advice given there and ran:

Code:

emerge iwl6030-ucode
emerge -q linux-firmware

(the first without the -C flag, since I didn't have anything installed before.) When I ran the first command I got something like:

Code:

The following keyword changes are necessary to proceed:
#required by iwl6030-ucode (argument)
=net-wireless/iwl6030-ucode-18.168.6.1 ~amd64

So I ran the second command which installed fine. Then i ran the first one again and got this error:

Code:

# emerge iwl6030-ucode

Use --autounmask-write to write changes to config files (honoring CONFIG_PROTECT).

Is that something to worry about or can I assume that the firmware is installed now?

This is what I get to dmesg now:

Code:

# dmesg | grep iwlwifi

So I'm assuming firmware is installed successfully?

However I still get this to iwconfig:

Code:

# iwconfig
lo no wireless extensions.

wlan0 no wireless extensions.

eth0 no wireless extensions.

Here's the output of some more commands:

Code:

Yes, it can be found at /lib/firmware

The error states ctrl_iface exists and seems to be in use - cannot override it
Stop wlan0 or temporarily remove it from the default runlevel, delete '/var/run/wpa_supplicant' - then start it with wpa_supplicant -iwlan0 -d -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf

It seems that your problem is either with wpa_supplicant.conf or maybe a missing dependency :wink:

Thanks a lot for your reply!

Yes you are right, there are a lot of iwlwifiXXXXX.ucode files there!

Actually it turned out that there is not file '/var/run/wpa_supplicant' so there was nothing the delete (maybe because I had rebooted since my last post). Now when I run wpa_supplicant -iwlan0 -d -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf I get this:

And than it gets into an infinite loop with the following output:

I guess the error is "Could not configure driver to use managed mode" but how do I fix that?

Here's my wpa_supplicant.conf file:

Code:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
network={
ssid="wifimrezha"
psk="myconnectwifi"
# The higher the priority the sooner we are matched
priority=5
}

Any ideas?

jopeto,

I don't know your router's configuration and if I'm not mistaken you have to match it's method of connection e.g. wpa, wpa2 etc.

Here's my section:

Code:

proto=WPA2
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP

In addition these messages Driver did not support SIOCSIWENCODEEXT and ioctl[SIOCSIWENCODEEXT]: Invalid argument seem to be a different problem.

EAPOL: Supplicant port status: Unauthorized seems to be related to key management.

iwlwifi depends on mac80211, cfg80211 and rfkill

Check your depends with

Code:

for m in $(lsmod|grep ^iwl|awk '{print $1}');do echo -n "$m :";modinfo "$m"|grep depends:;done

The output for my adapter is:

Code:

rt2800usb :depends: rt2x00lib,rt2800lib,rt2x00usb
rt2x00usb :depends: rt2x00lib,mac80211
rt2800lib :depends: mac80211,crc-ccitt,rt2x00lib
rt2x00lib :depends: mac80211,cfg80211

Good luck

Thanks for your reply. When I run

Code:

for m in $(lsmod|grep ^iwl|awk '{print $1}');do echo -n "$m :";modinfo "$m"|grep depends:;done

I get nothing as an output. I guess the reason is that I have everything built into the kernel and not as modules.

I also emerged rfkill and added

Code:

proto=WPA2
key_mgmt=WPA-PSK
pairwise=TKIP

to my wpa_supplicant.conf. But I'm still getting the same error.

Code:

# iwconfig
lo no wireless extensions.

wlan0 no wireless extensions.

eth0 no wireless extensions.

Code:

# ifconfig -a

I'm getting closer! I just found this link:
http://www.linuxquestions.org/questions/linux-wireless-networking-41/wlan0-no-wireless-extension-907830/
It suggests enabling Networking Support->Wireless->cfg80211 wireless extensions compatibility in the kernel configuration and recompiling the kernel. I just did it and now after running

Code:

wpa_supplicant -iwlan0 -d -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf

I get

Code:

# iwconfig
lo no wireless extensions.

wlan0 IEEE 802.11bgn ESSID:"wifimrezha"

eth0 no wireless extensions.

Wireless is still now working, but I thought I'd post this update in case someone is working on a solution. I guess from now it should be a question of tweaking things...

You should be using -Dnl80211 because iwlwifi is a netlink driver. That way you don't need the wireless extensions compatibility, which will go away at some point in the future.

jopeto,

That looks a lot better

Quote:

That's what I was trying to point out to you with

Quote:

iwlwifi depends on mac80211, cfg80211 and rfkill

with my previous post.

wpa_supplicant.conf is sometimes a little trial and error with all the possible settings, but it looks like you're well on your way to wireless

Good luck

Thanks to both of you. I finally got my wireless running, but I still have one small problem.

When I boot up, dhcpcd says that it looks for a carrier and it times out, so when I log on I have no internet access. Then if I run

Code:

# /etc/init.d/net.wlan0 start

the wireless connects and I can get on the internet. So how do I make this process automated so I don't have to wait an additional ~30sec at boot time for the time out and don't have to run the above command manually?

If it would be of any help, here's my

Code:

dns_domain_lo="homenetwork"

config_eth0="dhcp"

modules="wpa_supplicant"
config_wlan0="dhcp"
wpa_cli_wlan0="-G3600"
wpa_supplicant_wlan0="-D nl80211"

Gusar, I assume this is the -Dnl80211 you were referring to? I got the rest from this website:
http://en.gentoo-wiki.com/wiki/Iwlwifi

Thanks once again!

It looks like I'm all set!
