I observed the same behaviour with an arale running rc-proposed (build 369 today but earlier builds too). With the phone connected to a BT speaker (JBL Charge 3) and streaming music from the internet, I get frequent disconnections from either the internet stream or the speaker. Listening to the same streams with a wired headset works perfectly.
I did the following speed tests measurement this morning: 1. Streaming + BT on, 5 runs (kbps) 390, 794, 767, 618 and 455 avg: 604kbps 2. Steaming + BT off (loud speaker of the phone), 5 runs: (Mbps) 8.26, 11.30, 11.33, 11.62 and 10.61 avg: 10.62Mbps It is 17.6 times slower with BT on than off, and the reliability of the internet and BT connections is really bad. ** Changed in: canonical-devices-system-image Status: New => Confirmed ** Summary changed: - M10 wifi slows to a crawl when bluetooth is enabled + wifi slows to a crawl when bluetooth is enabled ** Changed in: canonical-devices-system-image Importance: Undecided => Critical ** Changed in: canonical-devices-system-image Milestone: None => 13 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1598584 Title: wifi slows to a crawl when bluetooth is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1598584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
