It is likely that your orinoco driver doesn't support scanning. Maybe this will help:

Good Luck,

try ad-hoc mode before scanning

eg. iwconfig ra0 mode ad-hoc

just replace ra0 with your network device and you should be able to scan for other networks.......if that doesn't work try it in conjuction with assigning a static address, netmask, etc to the wireless device.

sometimes i found i had to do, iwlist ra0 scan and iwlist ra0 scanning before anything appeared.

what kernel version are you running? do:
uname -a
and post the output. The newest orinoco driver is in kernel 2.6.13-rc2, which is orinoco 0.15
My iwlist scan didn't work either until I upgraded to 2.6.13-rc2 kernel.

I have the same problem using Fedora Core FC4, the kernel is 2.6.11. My attempts to build a new version of the module have failed, because FC4 doesn't come with kernel sources, and I can't figure out how to get kernel sources installed.

Here, try this one out: You have to download orinoco-0.15rc2.tar.gz (I think that's the one), untar it, go to the directory it makes, run "make" (no quotes), then gzip the .ko files it makes, su to root, and copy and paste those .ko files (now .ko.gz files) in your /lib/modules subtree (usually /lib/modules/(kernel version)/kernel/drivers/net/wireless).
Then, when you reboot (the safest way to figure it out) you should be running the 0.15rc2 version, which DOES support scanning! AND you dont have to go through the hassle of messing with pcmcia_cs!
And yes, it does require that you have the kernel sources in place, but once you get that, try this method, it worked for me!

Hope that was a bit helpful
