The relevant posts on this subject seem to be outdated. I'm trying to set up my laptop so I can select from a list of available wireless networks. Presently my method of connecting is
Code:
#iwconfig eth1 essid
#dhcpcd eth1

I'm now attempting to use a program I know little about, kismet. I'm trying to use the appropriate drivers so my latest attempt was to emerge orinoco. This failed with the following error message:
Code:
 * Found sources for kernel version:
 *     2.6.17-gentoo-r8
 * Checking for suitable kernel configuration options...
 *   orinoco-0.15_rc4 requires Hermes chipset 802.11b support (Orinoco/Prism2/Symbol) (CONFIG_HERMES) to be DISABLED.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.
 * Once you have satisfied these options, please try merging
 * this package again.

I see that it says CONFIG_HERMES should be disabled but by doing this the optional airport support goes away in the kernel configuration menu.

If you are using KDE, try KWifiManager.

Thanks for the reply but I don't use KDE.

kismet is serious overkill for connecting to wifi networks. You could try network manager, kwifimanager, waveselect, wifi-radar or wlassistant.

If you don't want to install anything else, the following will give you a list of available networks that you can connect to with your existing method:
Code:

# iwlist ethX scanning

If that's related to Airport 1 the latest kernel that can switch airport (hermes) modules to monitor mode was 2.6.12. Therefore I keep that kernel. And even at these times there was a patch needed for monitor mode but due to design changes they won't offer the patch for later kernels.

Add: I consulted again HOWTO-orinoco-drivers.txt and there is now spoken about 2.6.17+ . Did I miss something meanwhile?

Well, that's true about monitor mode on Orinoco, but to just scan for networks to connect with, you do not need this patch or monitor mode.

As for monitor mode, paoleela, it looks like you want this driver: http://www.kismetwireless.net/code/orinoco-0.13-dragorn-2.6.17.tar.gz

Compile it instead of the in kernel orinoco driver and it might work a little better for you.

So the thingy needed for running kismet and exploring networks isn't that called monitor mode?
And can I get this with a recent (2.6.17+) kernel and the patch?

At the moment I have to switch down to good old 2.6.12 everytime for kismet.

Yes, monitor mode allows the wireless device to capture all packets, even those not intended for your node. This driver should allow monitor mode on orinoco with modern kernels, but I haven't tested it personally.
