Hi Mital Kanabar or Palak Parikh (is there two of you?),

I probably misunderstood you.

The last posting specifically asked how to configure IP address and 
subnet mask: "How to configure IP and subnet mask". I tried to provide 
the pointers to help with that.

It wasn't clear to me, maybe I misunderstood you, that the device didn't 
show up in ifconfig. It seemed the most likely that you meant to say 
that it now shows up, because I thought it unnecessary to ask how to 
configure IP address when it doesn't show up, that's all...

Regards,
/P

 network driver is that it is attached but I can't see that interface in "ifconfig". How would I know, whether driver is
 working properly over the communication stack or not, as QNX doesn't show wireless network adapter (ral0) in network 
interface lists. This way I can't configure this card.

this way is to make sure this driver works first. It is not quite normal, normal is just to put it under /lib/dll/ but 
you said it crashed:(

are you using tcpdump or pcap? should work too with "SOCK=/ral".

Hi Yao,

Yes, you are right, first we should make sure that this driver works. I need to use PCAP with this adapter along with 
wired Ethernet adapter. 

Now, I have tried the latest "devnp-ral.so" normal way (just to put it under /lib/dll/) and typed "io-pkt-v4-hc -d /lib/
dll/devnp-ral.so". This time stack didn't crashed (with latest file) :), I could see all interfaces including 'ral0' 
wireless LAN interface, so I tried to configure IP to ral0 interface, but  I couldn't apply IP address, as  it showed 
network manager error (Snapshot of this sequence is attached herewith), and then it showed error like "Could not open 
Socket" so I took snapshot of io-pkt-v4-hc.core.  

Actually, I need to use capture packet for wired and wireless network adapter in one go using PCAP, therefore, I 
requested you to mount it normal way. 

If it is okay with you (please write me your contact number), I can give you a call, and follow your instructions for 
different trials (if it is more comfortable to you).

Please advise. 
Palak

fix a bug.
it will be good I can remote debug or have a card.

Hi Yao,

Thanks for your prompt action. I guess we are going close to the solution, however, this time io-pkt-v4-hc crashes, this
 was not happening with last "devnp-ral.so" file. I have attached snaps for sloginfo after attaching driver (by using 
command "io-pkt-v4-hc -d /lib/dll/devnp-ral.so"). After attaching driver, I have restarted QNX, and netmanager showed 
error "could not open socket" and I was not able to see any network devices. I have also attached io-pkt-v4-hc.core snap
 herewith. 

Please let me know what kind of details you will need in order to work on my system remotely or may be I will keep 
providing you snaps of all information you need for debugging this as quickly as possible on this forum, as this is my 
first priority/requirement for our projects.

Thanks a lot again for your consistent efforts. We appreciate it.

didn't understand why it crashed this time, I only enabled the debug code.
and it even didn't print out the mac address and last time it did.

just let me know how can I telnet or ssh your testing machine(put it in DMZ with a public ip or VPN) or wait until I can
 get a card.

Hi Yao,

I have consulted our IT dept. to allow this QNX system on the web. I am just wondering when are you planning to buy this
 card and fix the problem? Just for your information I have Linksys WMP 600N wireless adapter. 

Please reply so that  I can plan my project work accordingly.

thank you very much for your support.

Hi Yao,

This is the IP address of my QNX system which has wireless adapter: 129.100.228.130. Please advise me further steps as 
soon as possible.

Thanks,

Palak

I can't telnet to it, is it online?

Hello Yao,

Eureka..!! it seems to be working :). This driver is able to attach wireless network pci card properly without crashing 
io-pkt stack.....!!!!

I am just wondering , will I be able to configure IEEE 802.11e (WMM) for QoS. I know this card supports it, but 
wondering how to set it up?

Thanks a lot for all your support and effort in this regard. Our whole team appreciate your time and help.

Palak

I got the card and now it is working under infrastructure mode with WPA-EAP, NONE. PSK should work too.

fix a problem in bpf related code.
I can see the 802.11 layer packet in monitor mode with tpcdump.

Hi Yao,

Thanks for all your help. Sorry for delay in reply, I was out for some other project work. Now, I have copied this 
latest driver for RT 2860. QNX can detect it as well as configured it. However, while testing, I have noticed that it 
has limitation of number of packets received per second. I am receiving only around 300 packets per second, however, in 
my application I need to transfer 5000 packets per second. Each packet size is 125 bytes only. I do understand that 
wireless has bandwidth limitations, but I am getting only 300 kbps bandwidth on 54 Mbps wifi connection. 

Please advise.

Thanks.
