This is the only thread with an error even associated to mine....so here goes....
I have an AmbiCom WL1100C-CF wifi card. Prism2.
"Thanks for the reply. using Ambicoim WL1100C-CF . It's supposed to be prism2. "
Been here, done that. So, anyways...I've got a belkin wifi AP here, and with my winxp computer + PCI wifi card it works just fine. Strong signal, DHCP works...it just works.
Not my handheld. I use the network app to configure the AP and try to connect, but the light just blinks forever then shuts off. So, I SSH in (via cradle USB, not wifi

) and try to bring it up manually.
CODE
# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:10:7A:58:57:FB
BROADCAST MULTICAST MTU:1500 Metric:1

# iwconfig
lo no wireless extensions.
usbd0 no wireless extensions.
eth0 no wireless extensions.
#
(Note that I have to do the 'ifconfig eth0' because otherwise it won't show, because the device is not up.)
Now, I know the wireless extensions don't appear until I bring the interface up, but...
CODE
# ifconfig eth0 up
SIOCSIFFLAGS: No such device
"No such device".
*tries to connect through the tray applet, and while the light is blinking, brings the interface up*
*gasp*
CODE
# ifconfig eth0 up
#
No error! But the stupid script dies a moment later, and bring the interface down. I try to kill the process while it's running, but as soon as I do, the interface goes down. Either that, or I manage to nab all of the processes that it runs in time, and it stays 'up'. However, it's still lacking wireless extensions. If I try it anyways...
CODE
# iwconfig eth0 essid "Brantley"
Error for wireless request "Set ESSID" (8B1A) :
SET failed on device eth0; Function not implemented.
I have run the format time and time again. It never connects. I can't bring it up, except by the GUI applet, which also brings it down by itself shortly without connecting. I can bring it down, but not up. I can only bring it down after the GUI brought it up and I killed reams of scripts, but even then it's completly dead.
I AM NOT A HAPPY PERSON.
To answer a few questions now....
A) All commands were executed as root

I'm running the latest version of the special kernel and ROM (SL-5600)
C) I know it's not a problem with the AP
D) PLEASE reply here, even if it's a "I have no clue", so at least I don't go wondering if anyone ever read this.
E) I'm 4 feet away from the AP. The only thing inbetween the zaurus/wifi card and the AP is air and probably several hundred dang-near invisible pieces of dust.
