3Com OfficeConnect 3CRSHPW696 Wireless PCMCIA LAN

Paulten

Hello.

I just got a 3Com Office Connect Wireless PCMCIA card here at work.
I'm having problems getting it work.
I've never tried to set up a Wlan card or a PCMCIA card before.
This card is not supported in the current kernel. But after some googling I found out that it was based on the Atmel chipset.

My configuration :
Kernel 2.4.21 -With Wireless PCMCIA support
pcmcia-cs package is installed
Downloaded and Compiled all drivers from http://atmelwlandriver.sourceforge.net/
However it does not load any modules. lsmod shows none. Should it?
This is my atmel config :
Build all [y/N] :
Set extra module version information [y/N] : y
Build Debug version [y/N] : y
Build USB Drivers [y/N] : n
Build PCMCIA Drivers [y/N] : y
Build PCMCIA rfmd Driver [y/N] : n
Build PCMCIA 3COM Driver [y/N] : y
Build PCMCIA rfmd revision d Driver [y/N] : n
Build PCMCIA rfmd revision e Driver [y/N] : n
Build PCMCIA 504 Driver [y/N] : n
Build miniPCI Driver [y/N] : y
Build applications [y/N] : y
Build command line application [y/N] : y
Build Winter wxWindows application [y/N] : n

Then make clean , all , install
I tried to load the modules in /lib/modules/2.4.21/pcmia, but that made no changes.

When plugging it in, I see in /var/log/messages :
Jul 14 10:32:08 laptop kernel: cs: unable to map card memory!

/sbin/cardctl ident :
Socket 0:
no product info available

Inithially looking at what you described one thing I would do is not compile pcmcia support into the kernel, rather just let pcmcia-cs take care of it.

There have been several posts relating to how to get the atmel based cards setup.

Here is one page devoted to this topic. That page looks a little dated but it may contain useful information for you. Two more desciptions for getting these cards to work can be found here and here which come from the gentoo community.

If you continue to have problems please post the errors that you are getting.

Hope this helps,
arand

Hello.

My problem. I compiled out PCMCIA support from the kernel to instead use pcmcia-cs.
How do I start the PCMCIA-CS service? /etc/init.d/pcmcia start causes my computer to totally crash.

Thanks

Yes that would be bad. Quick question did you recompile pcmcia-cs? Not sure if this is required but this might help.

One thing you can to is run /etc/init.d/pcmicia restart. For me pcmcia is started when net.eth0 is brought up put putting this in the beginning of /etc/init.d/net.eth0

Paulten · Posted: Tue Jul 15, 2003 9:25 am Post subject:

Okay, thanks for the tip.

Yes I recompiled pcmcia-cs. Do I need support for Wireless LAN in the kernel? What about Wan? And no support what so ever for PCMCIA. Sorry about all the questions, pcmcia and wlan is greek for me :oops:

My computer crashes when I run restart pcmcia to. I tried that too. How can I check for sertain that pcmcia service is running?

Paste from my net.eth0.

depend() {
use hotplug pcmcia
}

Yes you do need to have wirless options compiled into the kernel. Just don't mark any specific card. Do not build pcmicia support into the kernel. Do not compile wan support. Do compile network support in also.

When you setup your laptop at anytime did you run an rc-update and added pcmcia anywere. If so then that would be starting up your pcmcia at boot. To check for this run a

my notebook crashes when insmodding the atmel driver _if_ the kernel is compiled --march=pentium4. p3 works fine. you didnt mention p4, but i assume you got a similar problem.

I have p4 yes. Should I try to compile as p3 ? How about the preformance then?

Thank you for the tip. I will try it in the morning.

1. Make sure your kernel is clean. Do a depmod -a and make sure there are no "unresoled symbols" for anything other then the atmel drivers. (they all start with pcmf...) do a make uninstall to remove the atmel drivers if you need to.

2. Say NO to "Set Extra Module Version Information." I have no idea what it is supposed to do, but for me, it caused all my problems. (this may be enabled with "build all" so don't say yes to it either.

3. Make sure you know what radio your card uses. Atmelwlandriver dropped support for Intersil radios back in December. If your card has one, you need to use the Dec 9 '02 snapshot. (more details on the website.)

4. Like the other poster said, turn off pcmcia in the kernel entirely. Use pcmcia-cs instead. Enable wireless lan in the kernel (first option) but don't select any cards.

5. Check /etc/pcmcia/atmel.opts and make sure your card is listed there. If not, add it using the info from "cardctl info" and "cardctl ident".

6. If that doesn't work, Radio Shack has the Linksys WPC11 for $50. It's on closeout in the stores and not available online. It has an Intersil radio and is already supported by pcmcia-cs, wlan-ng, and hostap. (I recommend using the last one. It has the most features with the least problems.)

Thanks for howto, really appreciate it! :!:

hi there,

i don't get my 3com card to work, because i don't know what to enable or disble while the 'make config'

here's my config:

arand · Apprentice Joined: 22 Apr 2003 Posts: 215

Just for the fun of life try saying to no to the command line applications.

xdamnx · n00b Joined: 29 Oct 2002 Posts: 61 Location: Germany

hmm didn't make any change, even ifi "no-out" to build applications.
it seems that the kernel directory isn't correct, because at
/lib/modules/2.4.21/
are only the modules the source is located at /usr/src/linux/
maybe it searches in my modules folder for the pcmcia stuff...

xdamnx · n00b Joined: 29 Oct 2002 Posts: 61 Location: Germany

i tricked a bit around and finally got them compiled, but needed to install them manually...

now the driver gives me following error:

arand · Apprentice Joined: 22 Apr 2003 Posts: 215

I am not sure why it is asking this question. I ran make config on the current version of the driver (2.1.2.2) and it gave me the same thing. It seems however that just put in anything almost and then run make clean, make all. It completed the make all with no errors.

I checked in the previous version (2.1.2.1) and there was no such question and I checked the .config file and there was no entry for pcmcia_src.

I would say give it a shot and see what happens.

xdamnx · n00b Joined: 29 Oct 2002 Posts: 61 Location: Germany

hmm seemed "somehow" to work...but now i got another problem...
if i put my card in it peeps 2 times, the led is on but nothing to find in
"ifconfig -a"
maybe i'm doing something wrong because i don't know very much about w-lan in linux...

what is the output of /sbin/lsmod?

lsmod gives me:

I guess what I would like to know is the pcmf502rd module being loaded by pcmcia-cs when you put your card in or is it something that was in your modules.autoload file. Also have you used iwconfig yet?

xdamnx · n00b Joined: 29 Oct 2002 Posts: 61 Location: Germany

hmm iwconfig cannot be found on my system...is it a special wireless pack which i need to emerge ??

<edit>
found a wireless-tools package, output of iwconfig after plugging in:

Hi guys.

Update. Found out that the PCMCIA card I have been struggling to get working, was not working at all.
I recived a new USB 3com OfficeConnect USB-Adapter 3CRSHEW696.
What do I need in my kernel now ?

I need a reboot to test

Okey, I just recompiled my kernel with USB support :
I got this output :

cd /lib/modules/2.4.21; \
mkdir -p pcmcia; \
find kernel -path '*/pcmcia/*' -name '*.o' | xargs -i -r ln -sf ../{} pcmcia
if [ -r System.map ]; then /sbin/depmod -ae -F System.map 2.4.21; fi
depmod: *** Unresolved symbols in /lib/modules/2.4.21/pcmcia/pcmf502r. o

depmod: register_pccard_driver_R1c442d6c
depmod: CardServices_Re4eef0a4
depmod: unregister_pccard_driver_Rdb348cd2

a depmod -a gives this :
depmod -a
depmod: *** Unresolved symbols in /lib/modules/2.4.21/pcmcia/pcmf502r3.o

What now? :/

I had a problem with pcmcia-cs not finding anything. You need to add the following to /etc/pcmcia/config.opts:

include memory 0xbc004000-0xbcffffff

Then download the pcmcia-cs 3.2.4 source and point the .config to it.

My .config is as follows:

CONFIG_PCI=n

#PCMCIA Drivers
CONFIG_PCMCIA=y
CONFIG_PCMCIA_502A=n
CONFIG_PCMCIA_3COM=y
CONFIG_PCMCIA_502AD=n

CONFIG_PCMCIA_504=n
CONFIG_PCI_506=n

CONFIG_USB_503A_RFMD=n
CONFIG_USB_505=n

Thanks.

This is my status..
I found a list over USB devices that worked :
http://www.wireless.org.au/~jhecker/atmeldrv/usbtable.html
My USB device is the first on the list.

The MAC isn't listed in my atmel.conf file.
To find out I typed cardctl ident :
cardctl ident
Socket 0:
no product info available
Socket 1:
no product info available

Is this only for pcmcia cards?
On the list I saw that it uses RFMD RADIO, I compiled that in the atmeldriver. But what is the name of the module ?
So far I tried to modprobe the USB modules :
[laptop!!#] ls /lib/modules/2.4.21/kernel/drivers/usb
acm.o bluetooth.o emi26.o pegasus.o usbnet.o usbvnet5_2958.o
audio.o catc.o kaweth.o printer.o usbvnet5.o usbvnetr.o

The pcmcia dir contains this :
ls /lib/modules/2.4.21/pcmcia
pcmf502r.o pcmf502r3.o pcmf502rd.o pcmf502re.o pcmf504.o

When I unplug and plug in the USB device I get this in /var/log/messages ::
Jul 21 16:48:10 laptop kernel: hub.c: new USB device 00:1d.0-1, assigned address 2
Jul 21 16:48:10 laptop kernel: usb.c: USB device 2 (vend/prod 0x506/0xa01) is not claimed by any active driver.

Thanks!
