NetworkManager without wlan

SUSE Product Topics SLED Networking

Problem: wlan can’t be activated in the NetworkManager icon of the task bar, the wlan checkbox is grey and untouchable. LAN is working fine.

Maybe there is a hint to a configuration issue in /etc/NetworkManager/NetworkManager.conf, because manually changing the content to “enabled=true” in the section for wireless doesn’t have any effect and has disappeared after reboot, whether or not I fire SuSEconfig. Hardware information doesn’t show any extraordinary content.

OS SLED11 SP4
Some output of some commands and some content of some files:

Hi
It maybe softblocked, have you checked the BIOS to ensure it’s enabled? Or does the system have a wireless hardware switch/Fn key combo?

The SLE 11 version should work;
http://download.opensuse.org/repositories/hardware/SLE_11_SP3/x86_64/rfkill-0.5-13.1.x86_64.rpm

Then as root user run to verify;

rfkill list
3

Hi, you’re right, it’s softblocked

I successfully installed rfkill from the i586 repository and got this reply

0: hp-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: yes
1: hp-bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: yes
2: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
3: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no

The led (function key) indicates that wlan should be working. Perhaps I made a configuration fault?

Hi
So what model HP, do you see any output from the following command?

lsmod |grep wmi

Hardblock means the Fn (Function key) + a key with the wireless icon on
it needs to be pressed a few times to cycle through bluetooth and
wireless enable/disable. Press the key combination and the run the
rfkill list command to see if any output changes.

Also try unblocking with;

rfkill unblock 0
rfkill unblock 1
rfkill unblock 2
rfkill unblock 3

The output doesn’t change. By the way, the led colour never changes, it always shows white. An extract from the hp manual

A contradiction?

After unblocking the response to “rfkill list” is

0: hp-wifi: Wireless LAN
	Soft blocked: yes
	Hard blocked: yes
1: hp-bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: yes
2: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
3: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

Right-clicking on the NetworkManager icon shows that wireless still is unavailable and may not be activated.

Hi
So did the system originally come with SLED, or was it running windows?

HP have some special drivers for both wireless and bluetooth, not sure
if available for that model and SLE 12, you would need to contact HP
Support.

If you reboot and press F10 to go to the BIOS and disable both the
bluetooth and wireless save/exit and restart the system and let it boot
to SLED, is the light now amber, and what is the output from rfkill?

Then restart the computer, press F10 again and re-enable the wireless
and bluetooth and save/exit and let the computer start up, does it all
change?

The BIOS main menue doesn’t allow to select the items for WLAN or Bluetooth and change their set-up. HP diagnostic log contains no errors.

I’m working with SLE11 SP4.

Today I tried to manually start wlan0, because I hoped to get more information what is going wrong. Therefore in YaST I changed network configuration from NetworkManager method to ifup, then rebooted.

hpc:~ # iwconfig wlan0 wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off

After reboot the reply was the same. I tried “ifstatus” and “ifup”:

[CODE]hpc:~ # ifstatus wlan0
wlan0 device: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
DHCP4 client NOT running
DHCP6 client (dhclient6) is running
. . . but is still waiting for data
wlan0 is down

hpc:~ # ifup wlan0

wlan0 starting wpa_supplicant

RTNETLINK answers: Unknown error 132

To check if there might be a driver problem I ran “wpa_supplicant -h”

Here are some lines of the reply

wpa_supplicant v0.7.1 Copyright (c) 2003-2010, Jouni Malinen <j@w1.fi> and contributors ... drivers: wext = Linux wireless extensions (generic) nl80211 = Linux nl80211/cfg80211 hostap = Host AP driver (Intersil Prism2/2.5/3) atmel = ATMEL AT76C5XXx (USB, PCMCIA) ndiswrapper = Linux ndiswrapper (deprecated; use wext) wired = Wired Ethernet driver ralink = Ralink Wireless Client driver options:

Shouldn’t there be a driver “ath9k” or should “wext” do the job? By the way, a configuration file “/etc/wpa_supplicant.conf” does not exist.

Thanks!

Hi
You should have some HP repositories then?

zypper lr -d

So your on a ipv6 network then?

No, none. Some time ago I had to install SLE from scratch and remove all repository connections.

No. Boot messages show that DHCP4+DHCP6 client is started.

Hi
I meant your using ipv6 not ipv4 :wink:

So if you use the HP code, it should add those repositories onto your
system for bluetooth and wireless…

AFAIK these are needed to get it out from being softblocked as rfkill
showed.

You might want to post over in the HP support forum and someone there
may be able to provide a link to the HP drivers.

So the output of “modinfo ath9k” doesn’t mean that the driver is maintained by SuSE?

The status of the module looks like this

Hi
AFAIK can tell kernel modules are working fine, until you can remove
the softblock neither wireless or bluetooth will work (rfkill).

You still didn’t confirm whether your connection is ipv6 or ipv4?

[/QUOTE]

Oops, didn’t I? It is ipv4.
In YaST → Network Configuration → global options the option ipv6 is activated and, I suppose, does no harm. Deactivating it and rebooting led to a problem with the text console (strg-alt-f1), which started very slowly because of waiting for DHCP4 client. Now ipv6 is activated and NetworkManager is responsible.

Hi
So you have the network cable in, if you unplug and run the same
commands?

I do suggest you pop over to the HP forums, there maybe some info on
unblocking those softblocks…

Let’s have a last try before switching to HP forums.
Some (edited) lines from /var/log/NetworkManager. Line 23 might be interesting. I still don’t understand why wireless is disabled by radio killswitch. Is there any configuration file which might be responsible?

Hi
No problems, we are here to help :slight_smile:

AFAIK it’s a windows thing, as in you need to boot into windows and
enable, since you have Linux, hard to do. HP provide a driver to
complete this in Linux for the HP systems, which again AFAIK is
provided by there repositories that get added when you active the
system for updates.

You could try an acpi option, but not sure… Fire up YaST
System-> Bootloader, on the Kernel tab add this in on the Optional
Kernel Commands part before the last entry showopts;

acpi_osi=\"!Windows 2012\"

Reboot and see if the Fn+wireless keys starts to work, verify with
rfkill to see if key presses change it.

Yes, now the wireless key starts to work. “rfkill list” now shows

0: hp-wifi: Wireless LAN Soft blocked: yes Hard blocked: no 1: hp-bluetooth: Bluetooth Soft blocked: yes Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no 3: hci0: Bluetooth Soft blocked: no Hard blocked: no
Pressing the key toggles hard blocking for hp-wifi and hp-bluetooth from ‘no’ to ‘yes’ and vice versa. Unfortunately both remain soft blocked.

Thank you!

Hi
Good news :slight_smile:

Now you should be able to clear the other softblocks;

rfkill unblock 0
rfkill unblock 1
rfkill list

I had the same issue with my HP ProBook 455 G1 but with SLED 12 during
beta testing but had it fixed.

If you upgrade to SLED 12 SP1 it should be all good. Remember SLED 11
will go out of general support soon, so no more updates.
