devn-prism.so & Netgear MA401 (WLAN)

QNX USERS QNX6 - OS

Hello,

I have bought the Netgear MA401 PCMCIA card which is listed at the supported hardware, because the network card inside my laptop isn’t supported by QNX.

Now I try to get them running at QNX6.2.1B.
For the first tests I switched off the WEP encryption.

Here is the output of “pin”:

1 0 Network C—I-±–X----- 81933 0x300 64 7
1 Empty ----MF---------- None
2 Empty ----MF---------- None
2 Empty ----MF---------- None

Here is the output of “pin cis”:

Then I used the following commands:

slay io-net
io-net -d prism mode=bss,station=qnx,verbose -p tcpip -v
ifconfig en0 192.168.1.2 netmask 255.255.255.0
route flush
route add 0.0.0.0 192.168.1.200

From the prism driver I got the following output:

PRISM (prism)

Vendor … 0x0
Device … 0x0
Revision … 0x0
I/O port base … 0x300
Interrupt … 0x7
MAC address … 00095b 548ddb

Then I tried to ping my WLAN router:

PING 192.168.1.200 (192.168.1.200): 56 data bytes
ping: sendto: Host is down
ping: sendto: Host is down

ping: sendto: Host is down
----192.168.1.200 PING Statistics----
13 packets transmitted, 0 packets received, 100.0% packet loss

At the “nicinfo” command I see, that the card and driver founds my WLAN.
The SSID and channel is right !!!

Here is the the output of “ifconfig”:

Any idea’s whats wrong ?
The driver founds my WLAN SSID and channel.
Why does it not work ?

Thank you very much for your help !!!

Has nobody an idea ?

How can I ensure that it’s not an interrupt problem or similar ?

I forgot to say, that the WLAN card works fine under windows.

Try running this on startup:

slay io-net
/sbin/io-net -p tcpip -d /lib/dll/devn-prism.so channel=10, ssid=linksys, station=qnx,verbose
sleep 5
/sbin/ifconfig en0 192.168.1.146 netmask 255.255.255.0
/sbin/route flush
/sbin/route add 0.0.0.0 192.168.1.1

You will need to change linksys for the ssid of your wireless hub, and also change the 192.168.1.146 for your own IP address, and 192.168.1.1 for your gateway.

Hello thegman,

I have put your commands into the file “/etc/rc.d/rc.local” and removed the spaces from the options of the prism driver.

I got the same error and outputs as before.

Have you also an MA401 card ? Get you the same output at “pin cis” ?

Best regards

Hi,

Just a wild guess. Maybe it’s your IRQ (7). Try to slay your devc-par before kicking your nic to life. If it works, try to assign another IRQ to your nic.

I’m not sure if it helps. It solved my problem with a PCMCIA adapter once.

Hello fmartens,

devc-par is not running. I get the following error while booting:

Unable to open device /dev/par1. (No such file or directory)

I slayed all processes which are not needed, restarted devp-pccard and net io-net.
But I get the same error.

In the past as I installed SuSE Linux 8.1, I had problems with the interrupts.
I had to use the following boot switch to get the interrupts working:

pci=acpiirq

I am no ACPI/APM expert, but does QNX use it ?
How can I ensure that it’s not an interrupt problem ?

Best regards

Hello fmartens,

But if I remember right, Linux showed interrupt 0 for the built in network card before using the boot switch.

Under Win2k the MA401 PCMCIA card gets ISA interrupt 11.

Hello fmartens,

I can remove the error message about /dev/par1 when I set the I/O and interrupt configuration from the parallel port in the BIOS from auto to maunal.

That looks really like an interrupt problem.

What can I do ?

Best regards

Fiffi
