Hi all

I am a new (gentoo) user, and I am having trouble getting wireless to work

I have a

lspci -k:
Code:

03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 3e)
       Subsystem: Intel Corporation Centrino Ultimate-N 6300 3x3 AGN
       Kernel driver in use: iwlwifi


and I have CFG80211, MAC80211, IWLWIFI enabled in kernel

I have emerged sys-firmware/iwl6000-ucode;
I have emerged wpa_supplicant and have the following:

/etc/conf.d/net:
Code:

modules_wlp3s0="wpa_supplicant"
wpa_supplicant_wlp3s0="-Dnl80211"
config_wlp3s0="dhcp"
config_eth0="dhcp"


/etc/wpa_supplicant/wpa_supplicant.conf
Code:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1

network={
    ssid="XXX"
    psk="XXX"
    proto=RSN
    key_mgmt=WPA-PSK
}


"iw dev" shows my wlp3s0, ifconfig shows the wlp3s0, iw dev wlp3s0 scan shows my wireless point.


HOWEVER after making the net.lo - net.wlp3s0 link and starting, I get the following error:

/etc/init.d/net.wlp3s0 restart
Code:

* Bringing up interface wlp3s0
*   Starting wpa_supplicant on wlp3s0 ...
Successfully initialized wpa_supplicant                                                                                                                                                                             [ ok ]
*   Starting wpa_cli on wlp3s0 ...
Failed to connect to non-global ctrl_ifname: wlp3s0  error: No such file or directory
*   start-stop-daemon: failed to start `/usr/bin/wpa_cli'                                                                                                                                                          [ !! ]
* ERROR: net.wlp3s0 failed to start



Can anyone help, as I have read many forum posts and the hours have been very frustrating.

Thank you in advance!

polqwa ...

sorry, I did see this first time round but as I couldn't see anything obviously wrong wasn't sure what to ask.

The error seems staightforward, its not finding /run/wpa_supplicant/wlp3s0, but I can't see why as wpa_supplicant is started without error.

So, tmpfs is enabled in the kernel? Is there anything in dmesg? Can you add the following to conf.d/net and post/pastebin the log ...

Code:
wpa_supplicant_wlp3s0="-Dnl80211 -d -f /var/log/wpa_supplicant.log"

Maybe using "wext" as driver instead of "nl80211"?

swimmer ... iwlwifi uses mac80211, a 802.11 layer, cfg80211 communicates with this layer and so its not using wext. Of course if CFG80211_WEXT is enabled then '-D wext' would work ... but its using the compatibility layer rather than wext itself. Anyhow, 'nl80211' is the correct (wpa_supplicant) driver for this card.

If you have configure CFG80211, MAC80211 and IWLWIFI to be enabled in the kernel image in hard (*), try to put them in modules (m). I can change the Linux behavior.

Are you sure that net.wlp3s0 point to net.lo in the /etc/init.d directory?

Logicien ... but this issue is with wpa_supplicant, it starts but wpa_cli doesn't find the ctrl_interface, also the interface is shown in iw, and ifconfig, so I don't think this is an issue with the drivers being modules or not.

In the above, net.wlp3s0 starts wpa_supplicant so the symlink must point to net.lo
