Re: [leaf-wisp] Using Senao card (former using several...)

Actually these errors are ok. It tries to assign IP addresses and so on to the interfaces, but they are not discovered yet by the PCMCIA daemon. Since PCMCIA daemon calls the script wireless-start script itself, these errors usually can be ignored.

Please send me contents of your /etc/network/wireless.config and /etc/network/if.config so that I can investigate what is going on with netcs3.

Or at least it seems to (I didn't measure what's on the air yet).
This is output after restartif:

Just two problems seem to persist:

1.- Why restartif complains about netcs1 and netcs2 (not such device)?

2.- Why I setup ESSID and txpower to 'amb3' and 100mW through the WISP-Dist Configuration panel but iwconfig shows different settings for netcs2? These settings can be changed by hand but are restored by rebooting or after restartif.

Well, it was a long way to reach this point and some steps must be done yet but thank you very much for your incredible help.

You have also to set "PCIC" if you want to set your own PCIC_OPTS.

Try using the following PCIC_OPTS:
irq_mode=0 pci_csc=0 poll_interval=100

where no interrupt is catched by hostap_cs which suggests an interrupt

problem 

with the PCI-PCMCIA bridge.
I tried at /etc/default/pcmcia the following entries:

PCIC_OPTS='irq_mode=0'

PCIC_OPTS='irq_mode=1'

PCIC_OPTS='irq_mode=1 irq_list=0'

PCIC_OPTS='irq_mode=1 irq_list=0 extra_sockets=1'

but I get the same output from iwconfig after restarting pcmcia subsystem.
So it seems the problem is interurpt related but I don't know how to isolate

the 

problem and solve it.
What do you suggest I can do?
Thanks a lot.

Looks like an IRQ problem. Check /proc/interrupts
