 Posted: Sun Jan 25, 2009 3:24 am Post subject: [SOLVED] Wireless Card Intel 3945abg SIOCSIFFLAGS: No |
 |
|
I followed this article (http://www.johnlewis.ie/2008/07/09/intel-wireless-3945abg-on-gentoo/) on setting up my wireless card with wpa_supplicant. I made a few modifications for a WEP 128bit Hex key. Then when I ran
| Code: | | /etc/init.d/net.wlan0 start |
I got this error
| Code: | | SIOCSIFFLAGS: No such device |
Searching for a bit I found that I needed to install iwl3945-ucode. I installed these and ran the same code above again. I didn't get the SIOCSIFFLAGS error but got something different (not sure what it was but it was an error with wpa_supplicant). I modified a line in .wpa_supplicant.conf and started getting the error above again and continued to get it when I removed the changes I made.
Here is the output from dmesg | tail
| Code: | [ 669.525800] iwl3945: Radio disabled by SW RF kill (module parameter)

Thanks in advance for any help as this is the last major issue before I can run Gentoo all the time

Hi, can you post this :
| Code: |
# cd /etc/init.d && ls -la

Also double check that your switch is enable :
| Code: |
Radio disabled by SW RF kill (module parameter)

I'm assuming you mean the switch on the front of the laptop, then yes it is enabled.

Can you post this :
| Code: |
# lsmod
# equery list iwl
# equery list ipw

By the way, you cannot use wicd and start manually net.wlan0.
So, do you want to try to make this thing works manually and then use the easy way with wicd ?
If so :
| Code: |
# rc-update del wicd
# cd /etc/init.d
# rm net.wlan0
# ln -s net.lo net.wlan0
|
Can you post this :
| Code: |
# cat /etc/conf.d/net
|

Some good news, I'm not sure exactly what happened but the wireless seems to be working. When I was at home (before) the first time wlan0 was trying to run (at bootup) it wasn't having the error I posted about but was having problems with the wpa_supplicant.conf. I came back to school last night, however, and I am able to connect wirelessly here.
I'm not sure what the exact fix was, but at some point I installed
│ │ <*> Intel Wireless Wifi Core │ │
│ │ [*] Iwlwifi RF kill support
In the kernel which might have been what fixed it. As for the wpa_supplicant.conf which I think was wrong, now I'm using PEAP-WPA key instead of the 128 bit hex WEP key for my home network.
I appreciate all of the help and I'll be sure to post back here if I start having problems again, unless you think there still might be something amiss with the configuration. |

Well I guess something is still wrong. I came home this weekend again and the same network I was having trouble with before is giving me the same problems. Like I mentioned, when I went back to school I was using a network with a WPA key and it was running fine on my laptop but the WEP key network at my house is still giving me trouble. Here is the output you asked for before
lsmod
| Code: | Module Size Used by
snd_hda_intel 335276 1
snd_hwdep 6532 1 snd_hda_intel
iwl3945 150388 0 |
equery list iwl
| Code: | * installed packages
net-wireless/iwl3945-ucode-15.28.1.6 |
equery list ipw
| Code: | | * installed packages |
cat /etc/conf.d/net
| Code: | # This network configuration was written by net-setup
config_wlan0="dhcp"
wpa_supplicant_wlan0="-Dwext"
essid_wlan0="any" |

| Hi, are you using WPA_supplicant because if you have 2 networks, then you should use wpa_supplicant or knetworkmanger to make your Wifi. |

| Thanks for your help, I think I got it working by compiling the wifi drivers as modules rather than part of the kernel. How can I mark this thread as solved? |
