This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

** Description changed: + SRU Justification + = + + [Impact] + wifi throughput numbers are good when device is running in WLAN only mode. + In STA+BT+BLE mode, we get expected wifi throughput numbers when BT - device is not connected. It drops to 5-6 Mbps from 30+Mbps as soon as BT - keyboard is connected. + device is not connected. However downlink throughput drops to 5-6 Mbps + from 35+Mbps as soon as bluetooth keyboard is connected. + + [Fix] + Enable UAPSD mode with some optimized parameters, so that wifi station can get Rx packets buffered by AP efficiently even if radio is shared with bluetooth + + [Test Case] + Conducted throughput tests and confirmed throughput gets dropped by 60% to 65% as expected(not more than that) when bluetooth keyboard connected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1706991 Title: ubuntu/rsi driver downlink wifi throughput drops to 5-6 Mbps when BT keyboard is connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1706991/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.13 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
