Saucy 13.10 Bluetooth Kills Wifi Centrino 1030

Asked by Ray Strilec on 2013-11-17

I am having multiple bluetooth problems since upgrading to 13.10. When trying to connect to my Jawbone Jambox : 1) I cannot get a2dp (high fidelity audio) to connect, which worked under 13.04. 2) I can connect the headset service, but when I do my wifi network connection stops working. I don't get an indication that the network connection dropped, it just stops. I cannot load webpages or ping the router IP address. Once I disconnect the bluetooth connection the wifi connection will resume working.

I have an ASUS U56E laptop with an Intel Centrino Wireless-N 1030 [Rainbow Peak] integrated wireless and bluetooth adapter.

So when you enable the bluetooth, the wifi turns off. Is that right?

Ray Strilec (rstrilec) said : #4

No. Wifi works with bluetooth enabled but stops once I connect to a device. I've only tried an audio devices thus far.

Do you have the latest BIOS (If your PC uses one)?

Ray Strilec (rstrilec) said : #6

Yes. I installed the latest BIOS last week while working on this problem.


echo "options iwlwifi 11n_disable=1 bt_coex_active=0 power_save=0 auto_agg=0 swcrypto=1" | sudo tee /etc/modprobe.d/iwlwifi.conf > /dev/null

As one big command. Reboot to test.

Ray Strilec (rstrilec) said : #8

Thank you. That fixed part 2 of the problem. I can now connect headset service to the Jambox and wifi works reliably. I've tested it several times.

However, Part 1 of the problem, connect a2dp is a little tricky. I am using blueman to manage my bluetooth connections. I have found that I can connect to the headset service of the Jambox but cannot connect to the audio sink. If I connect and then restart pulseaudio by issuing a pulseaudio -k command, I can then go back to blueman, right click on Jambox, and I will then see an "audio profile" option in the menu. I can select a2dp and it will work. This is less than completely reliable and once I disconnect, I have not found a way to reconnect. This could be a pulseaudio issue.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Luke Hudson (lukeletters) said : #10

I had this same problem.
Pinging my router gives an average of 2.3ms.
Connecting via bluetooth to the headset didn't change this significantly, but as soon as I used A2DP playback the pings go up to 11000ms or even get dropped completely.
This doesn't occur if using a different sound device, or if using HSP/HFP mode.

The workaround suggested by actionparsnip worked for me.

This is on Linux Mint 16 (based on Ubuntu Saucy).

Vladimir Ivanov (ivanov-bg) said : #11

I had same problem on my Ubuntu 14.04LTS laptop - when play music on my bluetooth speakers, the wi-fi connection stops (I remain connected to the router, but with no Internet connection).
I fixed my problem using the actionparsnip's suggestion, but skipped disabling 11n. Everything is OK now, but can somebody explain the remaining options from the command?
Thanks in advance

Hello everyone,

I had (HAD) the exact same problem. If this still affects you, the answer for me was here : which consist in the following command :

echo "options iwlwifi 11n_disable=1 bt_coex_active=0 power_save=0 auto_agg=0 swcrypto=1" | sudo tee /etc/modprobe.d/iwlwifi.conf > /dev/null


Buck Evan (bukzor) said : #13

This workaround fixed this issue for me:

    echo "options iwlwifi bt_coex_active=0" | sudo tee -a /etc/modprobe.d/iwlwifi.conf

The other workaround sets a bunch of unrelated options, and also blanks any pre-existing config.
