Thread: Connecting to bluetooth speaker stops wifi from working

    Default Connecting to bluetooth speaker stops wifi from working

    Hi,

    I'm running opensuse 13.1, upgraded from 12.3 on a Dell XPS. Wifi works smoothly and bluetooth also works smoothly. But when I connect a bluetooth speaker, my wifi data rate drops drastically to almost zero. The moment I disconnect the bluetooth speaker, the wifi data rate goes back to normal. I assumed the bluetooth was interfering with the wifi channel, so I tried all wifi channels from 1 to 11. I still faced the same issue.

    I didn't face this issue in 12.3. In 12.3 both wifi and bluetooth worked together without any problems.

    I am not sure how much help we can provide. Perhaps the BT problem has been
    fixed in a later kernel. Add the "Stable Kernel" repo at
    http://download.opensuse.org/reposit...able/standard/ and install
    kernel version 3.13 instead of the standard 3.11.

    If this does not help, then you need to post this where the Intel developers can
    see it - there are none here. The best place is the mailing list at
    linux-wireless@vger.kernel.org. When you post there, you will need to giver
    kernel versions, not openSUSE versions. I think you were probably using kernel
    version 3.7 with 12.3.
