When ath9k is the only wireless driver included in the build

driver becomes essentially unusable as you can't actually connect to
any WiFi network. By including WIRELESS_EXT into Kconfig we ensure
that build with ath9k and without other drivers (having WIRELESS_EXT
selected in their Kconfig) is actually usable.

Ubuntu installs NetworkManager by default, so if you want to manually
control the wifi card you'll have to tell NM to ignore the wifi device,
or turn NM off temporarily.

Because poking and configuring hardware is a privileged operation; tools
like NetworkManager selectively poke holes through that wall and often
require administrator passwords to do it, but at the end of the day its
an operation that can affect security and stability, and that means it
needs to be privileged.
In the end, you probably want to be using wpa_supplicant instead of
trying to configure stuff with iw directly.

Well, I guess I should say sorry. After all this discussion I've tried
to compile and boot kernel without WIRELESS_EXT once more. And now it
worked.
Last time I tried it was 3.0. Driver from vanilla sources didn't work,
so I compiled compat-wireless-3.0-2 and it did warn me during
compilation, something like "WIRELESS_EXT is not set, something won't
work". Then after boot syslog had somewhat the same message and
wireless didn't work. That's why I started this thread. Now with
3.1-rc2 everything works as is, no warnings in syslog and
NetworkManager connects to my network without any problems. I don't
know what has changed but I feel very sorry for all this mess.

NetworkManager is installed by default, and NM sends configuration to
wpa_supplicant using a different control interface, not the config file.
If you want to take the wifi interface out from NM's control, I think
you can add the interface to /etc/network/interfaces and NM will then
ignore it, and you can run wpa_supplicant manually with the '-i wlan0'
option to point it to the right interface, and when you've got a config
file, use '-c /path/to/config/file' to give it your configuration.
Or, since I'm a NetworkManager developer, is there something that you're
not sure how to make NM do, or are you just looking to experiment?

I've just tried to use iw and it didn't quite work for me. Maybe it's
interfering with something installed in Ubuntu by default but
connect/disconnect commands didn't seem to do anything. And why these
commands can be executed only as root?
Well, maybe in Ubuntu 11.10 it will work better.

Somebody better tell Fedora Rawhide - as of the version released on July 27,
their 'initscripts' RPM was still using iwconfig in /etc/sysconfig/network-scripts/ifup-wireless
So don't be quite so fast to be declaring WIRELESS_EXT dead just yet.

*sigh*
Please quote properly and delete stuff you're not replying to.
Also, have you discovered CONFIG_CFG80211_WEXT yet? It's even "default
y", so how did you manage to mess it up?

Well, any distro is free to include any package they want. They can even devote
resources to maintaining it after it is abandoned. Given the feelings among
developers about the WEXT methods, I doubt that will happen.
The distro is also including one of the drivers that need WEXT, which is what
the OP refused to do. If and when all such drivers are converted or removed, the
distro is still free to patch in the WEXT code, but again I doubt that will happen.
Anyone using deprecated methods has been warned.

Distributions? Using deprecated APIs?
That's unpossible! :-)

Since what version it's deprecated? Do user-space tools know about this new API?
Neither iwconfig nor iwlist worked for me without WIRELESS_EXT.

Given that nobody has stepped up to write patches to convert them to use
iw (or wpa_supplicant in the *correct* manner), and that for the most
part wifi on Fedora goes through NetworkManager and/or wpa_supplicant,
it's not surprising. I don't have any particular interest in keeping
the existing ifup-wireless iwconfig hackery around, instead if it's
converted at all, it should be converted to use wpa_supplicant instead,
in the manner in which I've described in the various bug reports that
keep coming up. That means not just pointing wpa_supplicant at a config
file, but instead keeping the options in the ifcfg file and writing out
a temporary wpa_supplicant config on-the-fly so that it integrates with
existing administrator expectations and workflow.

WIRELESS_EXT is not required for configuring wireless on recent
kernels - in fact, the WEXT API is deprecated in favor of nl80211 now.

I see Ubuntu already have wpa_supplicant installed and running.
Although its command line is not what suggested in documentation and I
don't see configuration file /etc/wpa_supplicant.conf. Does that mean
it works somehow differently than stated in documentation? And also
does all this mean that even if I'll be able to make wpa_supplicant
work as I need I won't be able to control wireless connection using
the standard Ubuntu's icon and it won't show me its state correctly?

I want to make the wireless work when kernel is compiled without

to do that?
