ACX100/ACX111 PCMCIA Wifi Card not find Access Point


I'm 99% there, i can feel it in my water...
HAving spent ages trying to install the wrong drivers for my planex PCMCIA WiFi card (MadWifI) i found the Homepage of the ACX100/ACX111 wireless network driver project.
acx100.sourceforge.net/ which pointed me in the direction of www.houseofcraig.net/acx100_howto.php which is oneof the best howto's i have ever read (i'm new to linux and over the last 3 weeks i have read a lot.)

I digress..

I followed the instructions, and am at a point where if i run iwlist wlan0 scan i get the results

wlan0 Scan completed :
Cell 01 - Address: 00:0F:34:CD:270
ESSID:"SBS-Guest"
Mode:Master
Frequency:2.417 GHz (Channel 2)
Quality=38/100 Signal level=13/100 Noise level=0/100
Encryption keyff
Cell 02 - Address: 00:0F:34:A0:45:60
ESSID:"SBS-Guest"
Mode:Master
Frequency:2.462 GHz (Channel 11)
Quality=33/100 Signal level=6/100 Noise level=0/100
Encryption keyff


So i can see our schools WiFi network...
We have NO WEP, no security at all, its an "OpenCampus"

However i can't pickup a DHCP Address using this network (and yes, i can on XP)

So i run an iwconfig and i get

lo no wireless extensions.

eth0 no wireless extensions.

wlan0 IEEE 802.11b+/g+ ESSID:"" Nickname:"acx100 v0.2.0pre8"
Mode:Managed Frequency:2.417 GHz Access Point: 00:00:00:00:00:00
Bit Rate:1 Mb/s Tx-Power=15 dBm Sensitivity=1/3

Link Quality:36/100 Signal level:11/100 Noise level:0/100
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

and i can see what the problem is

Access Point: 00:00:00:00:00:00

Its not associating with the Accesspoint

So i have a look at the logs

tail -100 /var/log/messages

and i can see

The line which is of interest to me is

Jul 11 08:19:32 localhost kernel: Association FAILED: peer station sent response status code 18: "Association denied due to requesting station not supporting all of the data rates in the BSSBasicRateSet parameter. TRANSLATION: peer station has an incompatible set of data rates configured, FIX IT!"!


Incompatible set of data rates...

So i look at the net_start config and the configurable portion looks like this

#!/bin/bash

GATEWAY=192.168.1.254 # set this if you did not set USE_DHCP=1

LED_OFF=0 # set to 1 to turn off the power LED to save power

MTU_576=0 # set to 1 if you have buffer management problems




Question, anyone have any idea how to associate this nic with the AP?

H/W Config

WIFI Nic = Planex GWNS54GM
Access Point = Cisco
No WEP or Security on network
Works With XP SP2

I'll post ANY info required...

It looks like your wlan card doesnt have an ESSID set. Do iwconfig wlan0 essid "put essid here without quotes"

I think to use DHCP you need to execute a command at the terminal. For me, I do dhcpcd wlan0. That sends a DHCP broadcast out from my wlan card. It depends on your distro though. Some you have to do netcardconfig, select your wlan0 device, and say yes to use DHCP broadcast.

Yeah these wireless networks are funny(on any OS really). Theres every hint to it working but you still dont get internet.

I added the ESSID no joy...
and dhcpcd doesn't work...

try..

Hi, i have that driver for my Texas Instuments card. I had the error before. It's todo with not having the essid set correctly and dhclient (dhcp request program) not being given a lease (ie. your wireless network isn't sending you an ip address.). Ensure that autorate is on, channel is correct (norm 11), your essid is set, and if dhcp isn't working still, try running dhclient wlan0. I think that should work.

Just for the record, I had this exact issue with my USR2210 card trying to connect to my new D-Link G604T wireless router; problem was that while talking to the USR 2249 AP I had before, I _had_ to explicitly set rate=11M as using anything else (22M, auto, you name it) would severely cripple performance.
Turns out that the new D-Link spits on my explicit rate, and wants rate=auto.
The USR 2210 then negotiates a 1Mbit rate with the G604T (eek), but it actually manages a respectable 550KB/s as it renegotiates up to 22Mbit (though I could get 660KB/s talking to the USR 2249 AP - but that's fine, my main laptop is now another which has an Intel 2200BG Wireless card and that one gets 1.2MB/s).

Thanks for tipping in the obvious but subtly not so rate=auto thingy
