Hi

I have a new Sony Vaio SZ2XP/C notebook, which contains an Intel 3945 Centrino wireless card. I've eventually managed to find a combination of kernel, ieee80211 stack and ipw3945 sources which start up the wireless, namely:

kernel 2.6.17
ipw3945 v 1.0.5
ieee80211 which comes with the kernel (1.1.14 I think?)

When I eventually get the whole caboodle up and running, I can associate with my access point (a Belkin Pre-N Mimo) and all the lights come on, but I get no traffic. The interface (eth2) handles ifup and ifdown just fine, but DHCP requests go un-answered, and static IP doesn't work. I think it's because I'm not *really* associated, so no packets are getting to the router. Nobody can ping me either.

Has anyone tried the ipw3945 against a pre-N A/P? Does it even work?

I also have another issue around auto-starting the ipw3945d daemon. The suggested method is to add a file under /etc/modprobe.d to start and stop the daemon but it only works once the daemon has already been running. At startup it has no effect. I believe others have had the same issue but google reveals no (practical) solutions.

Thanks for any help.

Your post is quite old so i don't know if you already got it, anway here is my experiences. I have the same kernel (2.6.17) as you, probably you also have the etch distribution.

For my Netgear WG511TA:
I downloaded the "linux-headers-2.6.17-2" and "linux-headers-2.6.17-2-686" and made sure my module-assistant was prepared (module-assistant prepare) and then simply made "module-assistant auto-install madwfi-source"

For my IntelProWireless3945
From ipw3945.sf.net I downloaded

"ipw3945-1.1.0.tgz" < Kernel Module
"ipw3945d-1.7.22.tgz" < Daemon
"ipw3945-ucode-1.13.tgz" < Firmware

And copied the
ipw3945d to /usr/local/sbin
ipw3945.ucode /lib/firmware

and build the module by making "make", afterwards copied the ipw3945.ko to /lib/modules/2.6.17-2

I assume you did it somehow similar but you still cannot connect... I had the same problem until i configured my interface properly with iwconfig... Sonehow i dont manage to configure it at boot time, therefore i "ifup eth2" it manually after making sure the daemon is running.
