 Posted: Mon Jan 22, 2007 5:58 pm Post subject: madwifi-ng doesn't create any interfaces |
 |
|
I've emerged madwifi-ng 0.9.2.1 without problem (and madwifi-tools 0.9.2 and wireless-tools 28). I'm running gentoo kernel 2.6.18-r6 with wireless extensions compiled in. I can modprobe ath_pci just fine, but no interface gets created, not ath0 nor wifi0. My WLAN-card is:
| Code: | | 00:05.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01) |
dmesg shows:
| Code: | ath_hal: module license 'Proprietary' taints kernel.
ath_hal: 0.9.17.2 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413)
wlan: 0.8.4.2 (0.9.2.1)
ath_rate_sample: 1.2 (0.9.2.1)
ath_pci: 0.9.4.5 (0.9.2.1)
|
Does anyone have a clue what might be wrong?

Wireless can be a bit flakey. Have you tried using the init script after you modprobed?
| Code: | | /etc/init.d/net.ath0 start |
If you can do a all of the following and post the results, might give a little more info on your problem.

net.ath0 doesn't exist. If I make a link to net and then run net.ath0 start nothing happens.
ifconfig -a:

eth0 and eth1 are NICs integrated on the motherboard.

iwconfig:

eth1 no wireless extensions.
lo no wireless extensions.

I used to use this wlan card on a machine running Slackware without any troubles. I used a madwifi CVS snapshot and it was rock steady. This was a year ago though.

Have you done a Did it give any errors? That should create the interface. You might have to ifconfig -a to see it though. If it doesn't, then | Code: | | # wlanconfig ath0 create wlandev wifi0 wlanmode sta |
Come to think of it... All this stuff is in the Madwifi HowTo.

I have run 'modprobe ath_pci'. It loads a couple of other modules as well. I don't get any errors. I don't see any wlan interfaces with 'ifconfig -a'. I've tried running wlanconfig but it doesn't work since there's no wifi0 device.

Your interface will be called ath0 not wifi0,
Try or that | Code: | | /etc/init.d/net.ath0 start |
And give us the recult of that if it doesn't work... ;o) |

I don't have an ath0 interface so I can't do an ifconfig ath0. That's the problem.

I've followed those instructions, but since the madwifi module doesn't create any wlan interfaces I can't do anything.
I need to get an ath0 interface before I can even try to get the wireless network working.

I can't remember now, but I think you have to create it yourself...
# cd /etc/init.d
# ln -s net.lo net.ath0
# ./net.ath0 start |

ath_pci is supposed to created it automatically, but it don't. You can also create it yourself from the interface wifi0 using 'wlancreate'. But since I don't have a wifi0 interface either, it doesn't work.
I've had madwifi working under Slackware without any problems whatsoever. Tonight I'm going to unmerge madwifi and manually download a tar ball and compile it and see if that works.

When you "modprobe ath_pci" you can see your iface with iwconfig. Then you have to start the iface. As mentioned before you have to
cp /etc/init.d/net.eth0 /etc/init.d/net.ath0
and then
/etc/init.d/net.ath0 start
and see if you get any errors
when you are done and you have a manual ip or from a dhcp server then you will see your iface with ifconfig.
Also try to see what you get from dmesg and if your iface is recognized as ath0 or ath1 or whatever athX. |

If modprobing doesn't create the interface, this command does | Code: | | # wlanconfig ath0 create wlandev wifi0 wlanmode sta |
Also check the Madwifi HowTo for other troubleshooting hints.

This is very strange, now it's working. When I modprobe ath_pci it loads a modules it hasn't loaded before, wlan_scan_sta, and creates ath0.
Well, I don't know what I've done, but it's working. Thank you everyone who has tried to help me.

One more question: how do I make net.ath0 automatically load the modules? I have to load them manually now before I run '/etc/init.d/net.ath0 start'.

These are the modules that have I added to my /etc/modules.autoload.d/kernel-2.6 in order to get my madwifi working correctly. Just listing them so you'll have something to compare to, I saw a post fairly recently where they mentioned that wlan_tkip doesn't always load correctly as a dependency.
| Code: | ath_pci autocreate=ap
wlan_scan_ap
wlan_ccmp
wlan_xauth
wlan_tkip
wlan_scan_sta
ath_rate_sample
ath_hal |

But I don't want them to load automatically when the system boots. Only when I start the ath0 interface. Is that possible?

Yeah just make a script that modprobes them all and then start up the interface. Then just run the script instead of the /etc/init/net.ath0 dealio.
Create a file where you want the script.
| Code: | | touch /root/wlan_script_ath0 |
open it up with nano
| Code: | | nano /root/wlan_script_ath0 |
copy all of the following into the file.
| Code: | #!/bin/sh
modprobe ath_pci autocreate=ap
modprobe wlan_scan_ap
modprobe wlan_ccmp
modprobe wlan_xauth
modprobe wlan_tkip
modprobe wlan_scan_sta
modprobe ath_rate_sample
modprobe ath_hal
/etc/init.d/net.ath0 start |
Then just change the permissions.
| Code: | | chmod 750 /root/wlan_script_ath0 |
Now all you have to do is run the script to modprobe everything and then start up the interface
| Code: | | /root/wlan_script_ath0 |

I had the same problem as in Peter's first post (no wifi0 created therefore there could be no ath0). In my case, it was that I'd forgotten to compile in CardBus support for the kernel 
D'oh!
Phil.
PS - If anyone tries to find it, CardBus support is under the PCMCIA section in the menuconfig.

| I got 2.6.19-gentoo-r7 and madwifi-ng-0.9.3 doesn't create interfaces ( and I do know what is wlanconfig for). it works great with 0.9.2.1 though. hope that helps someone. |

| The interfaces are supposed to be created automatically on module load, wlanconfig is not necessary for the initial interface. Do you still have an old /etc/udev.d/rules.d/65-madwifi.rules hanging around? What kind of card is it (cardbus, pci, etc.)? Did you recompile madwifi-ng-0.9.3 and madwifi-ng-tools-0.9.3? Please post lsmod and dmesg output. |

Madwifi 0.9.3-r2 doesn't appear to play nicely with my kernel (2.6.19-r5).
I saw the same problems as other in this thread had reported, i.e. the system wouldn't create an "ath" or "wifi" interface, so net.ath0 wouldn't do anything. Looking in dmesg, I also saw an error about my kernel not supporting automatic module loading, which is not correct. This was making the 'ath_rate_sample' module unhappy.
I rolled back to madwifi 0.9.2.1 and my wireless interface fired right back up.
I guess I'll hold off on upgrading to madwifi 0.9.3 (or newer) until I upgrade to a 2.6.20 (or newer) kernel. |
