 |
|
Hi All,
I'm having some problems getting my Netgear MA111 USB WLAN adaptor to work. Let's get the basics out of the way first:
Apple Powerbook 12" (Powerbook 6,1)
Kernel 2.6.1-benh1
linux-wlan-ng 0.2.1-pre20
I've entered the following into /etc/modules.d/aliases: | Code: | | alias wlan0 prism2_usb |
I've configured /etc/conf.d/wlan.conf as such: | Code: | WLAN_DEVICES="wlan0"
ChannelMinTime=200
ChannelMaxTime=250
WLAN_SCAN=n
SSID_wlan0="RLH"
ENABLE_wlan0=y |
and /etc/conf.d/wlancfg-RLH like this: | Code: | lnxreq_hostWEPEncrypt=true
lnxreq_hostWEPDecrypt=true
dot11PrivacyInvoked=true
dot11WEPDefaultKeyID=0
dot11ExcludeUnencrypted=true
PRIV_GENERATOR=/sbin/keygen
PRIV_KEY128=false
PRIV_GENSTR=""
dot11WEPDefaultKey0=<wep key here>
IS_ADHOC=n
AuthType=sharedkey
BCNINT=100
CHANNEL=6
BASICRATES="2 4"
OPRATES="2 4 11 22" |
Both these files look okay to me. After this, I found the linux-wlan-ng documentation to be a bit sketchy, so I tried a number of things.
First, I copied the wlan.agent file supplied with linux-wlan-ng to my /etc/hotplug directory and made sure hotplug is in the default runlevel.
When I executed /etc/init.d/wlan start, I get some strange output: | Code: | * Starting WLAN devices...
FATAL: Module prism2_usb already in kernel.
message=lnxreq_ifstate
ifstate=fwload
resultcode=success
Reading S-record file /etc/wlan//prism2_ru.hex...
prism2dl: No such file or directory
prism2dl: Failed to read /etc/wlan//prism2_ru.hex, exiting. |
The output from iwconfig wlan0 shows that the interface is up: | Code: | wlan0 IEEE 802.11-DS ESSID:"RLH" Nickname:"RLH"
Mode:Auto Frequency:2.467Ghz Access Point: 00:00:00:00:00:00
Bit Rate:2Mb/s Tx-Power:2346 dBm
Retry min limit:8 RTS thr:off Fragment thr:off
Encryption key:off
Link Quality:0/92 Signal level:32/154 Noise level:11/154
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0 |
2346 dBm !!?? I think that might exceed 802.11 specifications ;-)
But /var/log/messages looks rather more ill: | Code: | Apr 28 20:22:54 snapper ident: nic h/w: id=0x8026 1.0.0
Apr 28 20:22:54 snapper ident: pri f/w: id=0x15 1.1.3
Apr 28 20:22:54 snapper ident: sta f/w: id=0x1f 1.7.0
Apr 28 20:22:54 snapper MFI:SUP:role=0x00:id=0x01:var=0x01:b/t=1/1
Apr 28 20:22:54 snapper CFI:SUP:role=0x00:id=0x02:var=0x02:b/t=1/1
Apr 28 20:22:54 snapper PRI:SUP:role=0x00:id=0x03:var=0x01:b/t=1/4
Apr 28 20:22:54 snapper STA:SUP:role=0x00:id=0x04:var=0x01:b/t=1/12
Apr 28 20:22:54 snapper PRI-CFI:ACT:role=0x01:id=0x02:var=0x02:b/t=1/1
Apr 28 20:22:54 snapper STA-CFI:ACT:role=0x01:id=0x02:var=0x02:b/t=1/1
Apr 28 20:22:54 snapper STA-MFI:ACT:role=0x01:id=0x01:var=0x01:b/t=1/1
Apr 28 20:22:54 snapper Prism2 card SN: \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 |
And any requests made by iwconfig resultin failure. For example, iwconfig wlan0 mode monitor gives: | Code: | Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Operation not supported. |
The problem looks to me to be firmware based, although whether reading or writing, I'm not sure. Can anyone point me in the right direction?
Apologies, I am in 'verbose mode' tonight... ;-)

NOTE: linux-wlan-ng does not fully implement the wireless extensions
interface. This means that you can't use iwconfig and its kin to
set things up. Instead, read on! |
You have to use wlanctl-ng to configure that chipset, not iwconfig. For example:
| Code: | wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
wlanctl-ng wlan0 lnxreq_autojoin ssid=home authtype=opensystem |
To bring up the interface and join ssid "home"
Or:
| Code: | | wlanctl-ng wlan0 lnxreq_wlansniff enable=true channel=4 |
To enable packet sniffing on channel 4.

That's what i use for my wlan:
| Code: | wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
wlanctl-ng wlan0 lnxreq_hostwep decrypt=true encrypt=true
wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKeyID=0
wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11ExcludeUnencrypted=true
wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11PrivacyInvoked=true
wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKey0=we:pk:ey:he:re
wlanctl-ng wlan0 lnxreq_autojoin ssid=home authtype=opensystem

Awesome, it worked. Now, how about 128 bit encryption?
Or even better yet, somewhere that they list all of the mib attributes. |

| Code: | wlanctl-ng: - control utility for 802.11 devices
usage: wlanctl-ng interface|version|commands|mibs cmd cmdarg [cmdarg...]
where "interface" is the name of a wireless
network interface. Running 'ifconfig' will list
all network interfaces.
---> For a list of available commands, run 'wlanctl-ng commands'
---> For a list of available mib items, run 'wlanctl-ng mibs' |
