Lost my bluetooth..

Br0eTcHeN · 01-24-2012, 07:08 AM

Hi there,
i was trying around which distribution works best for me, so i installed fedora after i got everything to work i disabled bluetooth with the KDE tray tool. Then i installed Arch Linux got everything to work(didnt check for bluetooth then) but found fedora to be more comfortable so i wanted to go back.
after installing fedora the second time i found my bluetooth device was not working, system-settings said "device not found".
so i tried:
hwitool dev -> no device was displayed
lsusb -> there was no bluetooth device
rfkill list all -> shows an ideapad_bluetooth no blocked but no hci0
rfkill unblock all -> didnt enable anyhting (didnt really expect it to since nothing was found)
so i entered the bios and checked for it there, my wireless card and bluetooth share a hardware switch it is on, the option "wireless" is "enabled" in bios too.
after that i decided to run ubuntu from livecd to check if it would find the device, but it didnt.
i definitly think there should be a device hci0, it was working just 2 days ago, i dont think the hardware is failing the laptop is just a month old.
thx for reading and your suggestions.

Hi Br0eTcHeN,

I have the same issue here with wireless internet connection running FC16. For my Fedora 15 the wireless internet was working fine. But with FC16 it is just not the case for laptop.

Here is what I have done so far - maybe it can be useful:

Checked what is the maker of wifi driver:

Code:

    # lspci -v

    03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1030 (rev 34)
	Subsystem: Intel Corporation Centrino Wireless-N 1030 BGN
	Flags: bus master, fast devsel, latency 0, IRQ 51
	Memory at d7400000 (64-bit, non-prefetchable) [size=8K]
	Capabilities: [c8] Power Management version 3
	Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
	Capabilities: [e0] Express Endpoint, MSI 00
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [140] Device Serial Number 4c-80-93-ff-ff-0d-c6-b8
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

Downloaded the driver, then...

Code:

mv /opt/wifi/iwlwifi-6000g2b-ucode-18.168.6.1.tgz

tar zxf iwlwifi*.tgz
cd *.1

mv iwlwifi-6000g2b-6.ucode /lib/firmware

yum update -y
yum distro-sync
yum install akmod-wl
yum install kmod-wl -y

Reboot, login again... and the Bluetooth still shows the message: hardware disable. If I look on Network Settings >> Wireless, it shows: Wireless Unavailable.

I spent hours on it and still it does not work.

Any ideas? All comments and suggestions are highly appreciated.

Check to see if bluetoothd is running.

root@duelie:/home/cliff# ps aux | grep blue

root 3021 0.0 0.0 6848 968 pts/0 S+ 09:33 0:00 grep blue

Also check to see what modules you have loaded for bluetooth.

My system shows:

Quote:

lsmod | grep usb
btusb 11529 2
bluetooth 53100 9 rfcomm,sco,bnep,l2cap,btusb
usblp 11456 0

Hi Camorri,

Thanks for the suggestion..

here is the output:

Code:

# ps aux | grep blue
root       975  0.0  0.0  25236  1864 ?        Ss   16:42   0:00 /usr/sbin/bluetoothd -n
root      2567  0.0  0.0 109244   920 pts/0    S+   16:51   0:00 grep --color=auto blue

For "lsmod | grep usb" it shows no output. I also run:

Code:

yum install wicd

After reboot and login, it gives the message:

Code:

Could not connect to wicd's D-Bus interface.  Check the wicd log for error messages.

I tried to find what and where is the log error message from wicd, with no success so far.

Some other ideas?

threaderslash · 01-24-2012, 09:47 AM

Ok.. here is also what I found in the file /var/log/messages:

Code:

dbus[937]: [system] Activation via systemd failed for unit 'dbus-org.wicd.daemon.service': Unit dbus-org.wicd.daemon.service failed to load: No such file or directory. See system logs and 'systemctl status dbus-org.wicd.daemon.service' for details.

Then I run:

Code:

# systemctl status dbus-org.wicd.daemon.service
dbus-org.wicd.daemon.service
	  Loaded: error (Reason: No such file or directory)
	  Active: inactive (dead)

i dont have problems with wireless lan just bluetooth, wlan worked fine after i did blacklist the module acer_wmi in /etc/modprobe.d/blacklist.conf, seems to be an issue with atheros driver ath9k. i could see the wlan0 adapter but not enable it.

threaderslash · 01-24-2012, 04:12 PM

Thanks for the suggestion. Here is what I did:

Code:

# lsmod
wmi                     9737  1 dell_wmi

In /etc/modprobe.d, I added

Code:

blacklist dell_wmi

Here is what I can see on firmware with ls:

Code:

# ls /lib/firmware/iwlwifi-*
/lib/firmware/iwlwifi-1000-3.ucode  /lib/firmware/iwlwifi-5000-2.ucode
/lib/firmware/iwlwifi-1000-5.ucode  /lib/firmware/iwlwifi-5000-5.ucode
/lib/firmware/iwlwifi-100-5.ucode   /lib/firmware/iwlwifi-5150-2.ucode

/lib/firmware/iwlwifi-3945-2.ucode  /lib/firmware/iwlwifi-6000g2a-5.ucode

/lib/firmware/iwlwifi-5000-1.ucode  /lib/firmware/iwlwifi-6050-5.ucode

But the internet wireless still doesn't work.

Hi Br0eTcHeN,

Try to run...

Code:

yum -y install bluez*

Then tell how your bluetooth reacts.

Br0eTcHeN · 01-26-2012, 01:17 PM

thank you two, i just did a bios update and my bluetooth device returned.
