Hello all,
I'd appreciate some help troubleshooting my wireless connection.
I have a Toshiba Satellite L305 series laptop running Debian
sid with a recent, stock Debian kernel version 2.6.29-2-486.
$ lspci | grep Atheros
05:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
I am seeking to connect to a D-Link 614+ wireless router.
For initial testing, the AP is unencrypted, unsecured.
My wife's G3 i-Book with AfterTheMac USB wireless adapter
connected just fine, on the first try.
I believe I have the modules I should have:
$ lsmod | grep 80211
mac80211 139680 1 ath5k
cfg80211 21576 2 ath5k,mac80211
My wireless network interface is present:
$ iwconfig wlan0
wlan0 IEEE 802.11 ESSID:""
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=0 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
$ ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:21:63:82:82:40
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
However, I don't find the D-Link 614+:
$ iwlist wlan0 scan
wlan0 No scan results
And of course, dhclient fails to find a server.
Am I missing something? What could I try next?
I'd appreciate any pointers.
Thanks.

Hi Luis,
I've tried this, with no obvious change.
I've not used the 'ip' command before in my networking
explorations, always relying on ifconfig to bring up
devices.
Ifconfig reports that wlan0 is UP. Is there any other
kind of UP that I need to understand?
Another question: From the point of view of setting up
wireless, if the wlan0 device is UP, should
'iwlist scan' return a list of access points?
Or are there any other conditions to be met?
Thanks.

Hello ;-)
Can you please sent the dmesg output when ath5k loads ?
Also do you see any messages on dmesg while scaning ?

My naive compile of madwifi failed; however, I was able
to boot up the factory Windows Vista.
Vista advised me to:
1) turn on the hardware wifi switch <blush>
2) use the hotkey combination to enable wifi
Then I was able to see the AP in Vista's Connect-To pane.
Rebooting under 2.6.30.1 for amd64, the driver
still doesn't find access points.
None of my hotkeys work under Linux (the toshiba_acpi
driver doesn't load), so I can't press the Fn-F8 key
combination to enable wifi.
It may be that the wireless driver is fine, but that
I simply can't (yet) enable the hardware.
Thanks for your suggestions.

It might be worth trying compat-wireless or 2.6.31-rcX. Support
for reading the card's internal rfkill state was added in the
post-2.6.30 time-frame.

should have worked, but I'm glad you're making good use of iw :)

And voila! I have an IP address on wlan0.
I can't think of anything more that I need. :-)
Oh, maybe a pointer for others.
Perhaps I was just missing the iw 'connect' incantation?
'iwlist' was a complete red herring; didn't help me
find my AP.
http://linuxwireless.org/en/users/Documentation was the only
site of several I visited mentioning 'iw' at all!
And at linuxwireless, I find no example of using 'iw' to set
up a connection. I'd be glad to contribute one.
Thanks Bob, Nick and others for your tips.

I installed compat-wireless against my 2.6.30.1 kernel,
and also the iw command.
I've read some docs, however I'm not sure what the next step should be.
My general idea is that I should be able to see a list of
access points, however iwlist doesn't tell me anything new.
# iwlist wlan0 ap
wlan0 Interface doesn't have a list of Peers/Access-Points
I'm appending some diagnostics.

I compiled the kernel with debugfs support for wireless. Can someone
point me to helpful docs in setting this up.
Also, is there a chance that another driver would serve me better?

Hmm. It does work _now_, provided the interface is UP.
That may be thanks to having a recent kernel with the latest
compat-wireless drivers.
I was also misled by assuming iwlist's 'ap' option would
provide useful information.
To summarize what I now know, the steps to follow for basic
wireless connectivity to an unencrypted network would be:
1. kernel and driver setup - use compat-wireless
2. set wireless interface to UP
ifconfig <interface> up
3. find available networks using
iw dev <interface> scan
or
iwlist <interface> scan
4. connect to a network using
iw dev <interface> connect <SSID>
5. acquire IP address, typically by
dhclient <interface>

Joel

Is there anything I can glean from these diagnostics?
I can certainly compile a more recent version of the
driver.
Anything else I might try to get this hardware working
for me?

O.K. can you try madwifi so that we can eliminate the possibility of a

It hasn't for many years, really. Oh well, not much we can do about it.

This isn't strictly necessary if you know the SSID already.

The old way of doing this would be
iwconfig wlan0 essid <SSID>
But as long as you don't need ancient hardware, you're probably better
off using iw. You can also use
iw dev <interface> connect -w <SSID>
if you run a current git snapshot, and it will wait for the connection
to be established or fail and print the status.
Oh and if you're just doing this on the command line you can do
iw <interface> connect <SSID>
(i.e. leave out the "dev"), but please don't script it that way :)
