Which "operation failed" You have no idea tht went wrong, but you think
that you can selectively report from the full thing and that your
selection will be an accurate indication of the problem.



The /etc/network/interaces looks somewhat like this

auto ra0
iface ra0 inet dhcp
wireless-essid MyESSID
wireless-key 12345678
wireless-channel 5


On which operating system? And why in the world would you specify the
channel?


First problem is that the interface ra0 doesn't come up automatically
during

Probably the module is not loaded.
Make sure that th emodule is getting loaded.
lsmod


boot. The script therefore doesn't work and I have to start it by hand:

ifconfig ra0 up

? ifconfig will do absolutely nothing of any worth. Your system has to load
the module to run your wireless card. That module then selects and
interface. Not you.



Does anyone know in what script I need to add a 'ifconfig ra0 up'
command?

None. That is not the problem.


Once it's up I can check it with the 'ifconfig' and 'iwconfig' commands.
That works fine but the interface isn't configured.

And if you do
iwlist s
do you get any reports of anything?



Now I do a :

ifup ra0

but I it returns (after 10 seconds or so):

operation failed.

That's it, no error indication. Is there a log file where I can view
what
the problem is?

/var/log/messages
dmesg

Does your rt2500 module get loaded? ("make install" should make sure it
does)

If you change the script in /etc/modprobe.d/wireless by adding the

There isn't a /etc/modprobe.d/wireless file on my system so I can't take
your advice.

And your system is what? Almost all distributions use slightly different
ways of setting up . modprobe.d is in Debian based systems. The Linux
kernel people use modprobe.conf



I think I've figured out that the 'Operation failed' message is actually
coming from the 'pump' DHCP client. Does that ring a bell with anyone?

If the previous line says
getting dhcp address: Operation failed
then yes, the problem is getting a dhcp address. It may have nothing to do
with your card at all.


lsmod
and look for your module driver for the card
iwlist s
and look for reports of wireless access points.
ifup <name of the interface reported by iwlist to have access points>
Then look at
iwconfig
to see if it is connected to the access point.

If all of the prvious work then it is dhcp. Perhaps you forgot to set up
your wireless router to run dhcp.

(I have found dhclient better than dhcpcd but I have not tried pump.)
