 Posted: Fri Dec 05, 2003 9:29 pm Post subject: wlan-ng drivers and WEP |
 |
|
I have read alot of the wep related posts but have not found any with the same break that I have here, this is the steps I have taken to setup my wireless:
First of all I am using a Microsoft (I know, but lets not go there) USB Wireless adapter (MN-510).
| Code: | USE="usb" emerge linux-wlan-ng
emerge wireless-tools
modprobe prism2_usb prism2_doreset=1
|
added iface_wlan0="dhcp" to /etc/conf.d/net
At this point I can connect to a Non-WEP access point by doing the following:
| Code: | /etc/init.d/wlan start
dhcpcd wlan0
|
However I need WEP so I continue....
created /etc/conf.d/wlancfg-<WEP enabled ssid> and edit to be the following:
| Code: | lnxreq_hostWEPEncrypt=true
lnxreq_hostWEPDecrypt=true
dot11PricacyInvoked=true
dot11WEPDefaultKeyID=0
dot11ExcludeUnencrypted=true
PRIV_GENERATOR=/sbin/keygen
PRIV_KEY128=false
PRIV_GENSTR=""
dot11WEPDefaultKey0=XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX
dot11WEPDefaultKey1=
dot11WEPDefaultKey2=
dot11WEPDefaultKey3=
IS_ADHOC=n
AuthType="sharedkey"
BCNINT=100
CHANNEL=6
BASICRATES="2 4"
OPRATES="2 4 11 22"
|
Just to make sure I also have tried commenting out all the PRIV_ lines as I am using a shared key.
Now my WEP should be setup so I start the interface and try to get an IP address, which times out. dmesg gives me the following info:
| Code: | linkstatus=CONNECTED
wlan0: no IPv6 routers present
dhcpcd[3551]: timed out waiting for a valid DHCP server response |
So it appears it is not using the key, I have also tried putting the key in Key1= because the access point lists them 1 - 4 and I am using 1, still no luck.
Running iwconfig wlan0 gives me the following info:
| Code: | wlan0 IEEE 802.11-b ESSID:""
Mode:Managed Frequency:2.437GHz Access Point: XX:correct MAC:XX
Bit Rate:11Mb/s Tx-Power:2346 dBm
Retry min limit:8 TRS thr:off Fragment thr:off
Encryption key:off
Link Quality:92/92 Signal Level:-40 dBm Noise level:-99 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
|
I then try to set the encryption manually using iwconfig but no matter what command I try to give it all I get is the following error:
| Code: | iwconfig wlan0 key xxxxxxxxxxxxxxxxx
Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Function not implemented.
|
Any one dealt with this or am I missing something obvious? Please shed some light.
Thanks.

I could never get the wlan drivers to play nicely with my WEP.
Using the standard 2.6 kernel drivers and pcmcia-cs and wirelesstools I've got it to work nicely  |

I should have mentioned, I am using the 2.4 gentoo-sources kernel with USB.

The key to getting the wlan-ng drivers to work is to update the firmware on your card. Most of the drivers features are based on the firware. I was having lots of problems till I updated mine.

I checked the intersil firmware on this thing, and its 0.83.
Is there a newer one available? do you know where I can find it?
Thanks.

Here is a link to an upgrade site. Upgrading the firmware is a little risky because most manufactures don't support it.

Good luck. From what I read, its best to use a windows util to update the firmware.

One thing I missed in your previous post is that wireless tools do not work with the wlan-ng drivers, i.e. iwconfig. You need to do the configuration via the wlan-ng config files. Since most gui programs use wireless tools you may want to consider going with the hostap drivers. If you stay with wlan-ng the config file is in /etc/conf.d/wlan.conf.

Thanks! I risked the update and it went smoothly, so I am going to see what I can do now.

do not upgrade your firmware, it's just bullshit !!!
you just need to do this before using dhcpcd eth1
| Code: | | iwconfig eth1 essid ... key open XXXXXXXXXXXXX. |
it's just the open who was missing ... |

I don't think either of the above solutions is right (upgrading the firmware, or using iwconfig). I'm running into the same problem with wlan-ng and WEP, and here's what I know for sure:
- This same card (PCI PLX card + Belkin PCMCIA card) worked fine, WEP enabled, in an older version of wlan-ng on Red Hat 8
- I have not changed the firmware since, so this has nothing to with firmware revisions
- iwconfig (i.e. wireless extensions) is supported by newer releases of wlan-ng, but wlanctl-ng should be the right way of doing this. In particular, "iwconfig eth1 essid ... key open XXXXXXXXXXXXX" does not work.
- The Gentoo /etc/init.d/wlan script uses wlanctl-ng to enable WEP on the card, and the reported return codes indicate success, but iwconfig on wlan0 still shows that encryption is not enabled on the card.
- But iwconfig on another machine (my home-built access point running Red Hat 8 and the hostap driver) shows encryption enabled, and displays the right WEP key.
Therefore: there is something wrong with either this release of wlan-ng (0.2.1-pre11), or with the way the Gentoo scripts are initialising the card.
Here are the wlanctl-ng commands that are being issued by the startup script (I've omitted the actual WEP keys), and all are being reported successful:
| Code: |
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKeyID=0
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11ExcludeUnencrypted=true
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11PrivacyInvoked=true
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKey0=xxx
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKey1=xxx
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKey2=xxx
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKey3=xxx

Hi,
Sorry for bringing this topic back, and going off topic, but Valkur mentioned he used a MN-510, I also have one and was trying to set it up. I emerge both linux-wlan-ng, and wireless-tools, but when I do the modprobe it says prism2_usb is unknown, or something like that. Can you tell me what I am doing wrong? Please help, thanks
EDIT: I wasn't setting USE="usb" and emerge linux-wlan-ng on the sme line, or exporting. Doh. |

| I found that if I used the genstr settings in the wlancfg-ssid file and made sure NOT to put in a specific key code - it worked! |

| I am still having problems with this. I can't for the life of me get Encryption turned on. I have the settings mentioned for the wlancfg file but it still show nothing. Anyone ever solve this? |

| Thanks to desh for the commands I've managed to manualy set up a D-Link DWL-122 usb with encryption doing it manually via a shell script. |

I have all that info in my config file already? Should I still type it in the shell? |

Worth a try!
I need to do it via a shell script as I've installed the drivers, default install with usb, on a remastered Knoppix boot cdrom.
Just wish I could work out how to get the device configured for Ad-Hoc. |
