hp elitebook 6930p: wireless switch not working


hi there,

i got a new hp6930p laptop. after installation of ubuntu 8.10 amd64 alternate most things work, except wireless.
console screenshot:

Code:
>sudo ifconfig wlan0 down
>sudo ifconfig wlan0 up
>sudo iwlist wlan0 scanning
wlan0 No scan results
>dmesg
...
[ 2924.348129] iwlagn 0000:02:00.0: PCI INT A disabled
[ 2933.320469] iwlagn 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
[ 2933.320714] iwlagn 0000:02:00.0: restoring config space at offset 0x1 (was 0x100002, writing 0x100006)
[ 2933.328139] iwlagn: Radio disabled by HW RF Kill switch
[ 2933.348308] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 2985.864068] CE: hpet increasing min_delta_ns to 15000 nsec
the wireless touchbutton/switch above the keyboard is always colored orange which, reading the manual, means "off". does not change when i touch it.


how can i activate the wireless-switch?
any ideas?

thank you in advance,
cf050

What wireless card does your laptop have? Probably the wireless light will turn to green (indicating on) once you have installed the correct driver or firmware file for it. Perhaps you are in the unfortunate position that your card is not supported out-of-the-box by Ubuntu.

hi rjwilmsi,
thank you for your response.
my wireless card is an Intel PRO/Wireless 5100 AGN Rev.0x54, at least this is what dmesg tells me:

Code:
[   12.409898] iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27ks
[   12.409901] iwlagn: Copyright(c) 2003-2008 Intel Corporation

[   12.417072] pcmcia: parent PCI bridge Memory window: 0xdc000000 - 0xdfffffff
[   12.417976] iwlagn 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
[   12.418006] iwlagn 0000:02:00.0: setting latency timer to 64
[   12.418086] iwlagn: Detected Intel Wireless WiFi Link 5100AGN REV=0x54
[   12.452890] iwlagn: Tunable channels: 13 802.11bg, 24 802.11a channels
[   12.453107] iwlagn 0000:02:00.0: PCI INT A disabled
[   12.453691] phy0: Selected rate control algorithm 'iwl-agn-rs'
...
from this, i also assume that the correct driver is found (iwlagn).
could it be that the wireless-button is not configured correctly and how could this be corrected?

thank you again,
cf050

What happens when you try to set up a wireless connection? The driver setup looks correct.

rjwilmsi,
for instance, the commands
Code:
#> ifconfig wlan0 up
#> iwconfig wlan0 essid <MySSID>
Error for wireless request "Set ESSID" (8B1A) :
        SET failed on device wlan0 ; Resource temporarily unavailable.
When I repeat
Code:
#> iwconfig wlan0 essid <MySSID>
the command is accepted (no error message), but

Code:
#> iwconfig wlan0

wlan0     IEEE 802.11abgn  ESSID:"MySSID"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=15 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
          Encryption key:off
          Power Management:off
          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
the device does not capture any signal and the AP is not found.

In dmesg I find after the first attempt to configure the device

Code:
#> dmesg
...
wlan0: Failed to config new SSID to the low-level driver
BTW, the AP (Buffalo WHR-HP-G54) uses protocol IEEE 802.11g.

If you do
Code:
iwlist wlan0 scan
can you see your network?

As I already noted in my first post, I cannot see my wireless network:

Code:
#> iwlist wlan0 scan
wlan0     No scan results

thanks for the link. i installed the latest drivers as suggested but that did not help either. i still believe it has to do with the wireless switch above the keyboard. it still does not change its color. do you know how to check its configuration?

Check in the BIOS for any options about the wireless but I would think the LED will go green once you get a wireless connection.

Hey there cf050.

I have had the same problem with two different HP laptops.
The sulotion I found working on both of them was to go to BIOS and do a BIOS reset.
I allready had the "default" settings in BIOS so this diden't affect anything really, but the wireless started working directly after a reboot.
Give it a try

Good luck.

fusco, your tip
Quote:

works also for me. one should be careful to re-enable/disable the same options as before, e.g. the ahci setting in the device section of the bios.

thanks
