[Kernel-packages] [Bug 2058752] Re: ath11k high jitter and packet loss when operating in 802.11ax mode
unfortunately the problem is not actually gone in noble. I have upgraded to the beta and are having significant but intermittent problems. On 6.8.0-31-generic I get periods of normal traffic mixed with 100% packet loss for some seconds. This looks as follows: 64 bytes from 192.168.16.77: icmp_seq=2622 ttl=64 time=2.47 ms 64 bytes from 192.168.16.77: icmp_seq=2623 ttl=64 time=2.80 ms 64 bytes from 192.168.16.77: icmp_seq=2624 ttl=64 time=2.77 ms >From 192.168.16.231 icmp_seq=2637 Destination Host Unreachable >From 192.168.16.231 icmp_seq=2638 Destination Host Unreachable >From 192.168.16.231 icmp_seq=2639 Destination Host Unreachable >From 192.168.16.231 icmp_seq=2640 Destination Host Unreachable >From 192.168.16.231 icmp_seq=2644 Destination Host Unreachable >From 192.168.16.231 icmp_seq=2645 Destination Host Unreachable 64 bytes from 192.168.16.77: icmp_seq=2646 ttl=64 time=162 ms 64 bytes from 192.168.16.77: icmp_seq=2647 ttl=64 time=1.95 ms 64 bytes from 192.168.16.77: icmp_seq=2648 ttl=64 time=44.3 ms 64 bytes from 192.168.16.77: icmp_seq=2649 ttl=64 time=143 ms 64 bytes from 192.168.16.77: icmp_seq=2650 ttl=64 time=2.37 ms 64 bytes from 192.168.16.77: icmp_seq=2651 ttl=64 time=151 ms 64 bytes from 192.168.16.77: icmp_seq=2652 ttl=64 time=2.69 ms 64 bytes from 192.168.16.77: icmp_seq=2653 ttl=64 time=6.66 ms 64 bytes from 192.168.16.77: icmp_seq=2654 ttl=64 time=47.2 ms 64 bytes from 192.168.16.77: icmp_seq=2655 ttl=64 time=40.1 ms 64 bytes from 192.168.16.77: icmp_seq=2656 ttl=64 time=44.9 ms 64 bytes from 192.168.16.77: icmp_seq=2657 ttl=64 time=1583 ms 64 bytes from 192.168.16.77: icmp_seq=2658 ttl=64 time=560 ms 64 bytes from 192.168.16.77: icmp_seq=2659 ttl=64 time=1506 ms 64 bytes from 192.168.16.77: icmp_seq=2660 ttl=64 time=457 ms 64 bytes from 192.168.16.77: icmp_seq=2661 ttl=64 time=809 ms 64 bytes from 192.168.16.77: icmp_seq=2662 ttl=64 time=3014 ms 64 bytes from 192.168.16.77: icmp_seq=2663 ttl=64 time=2005 ms 64 bytes from 192.168.16.77: icmp_seq=2664 ttl=64 time=982 ms 64 bytes from 192.168.16.77: icmp_seq=2665 ttl=64 time=2.47 ms 64 bytes from 192.168.16.77: icmp_seq=2666 ttl=64 time=2471 ms 64 bytes from 192.168.16.77: icmp_seq=2667 ttl=64 time=1464 ms 64 bytes from 192.168.16.77: icmp_seq=2668 ttl=64 time=440 ms 64 bytes from 192.168.16.77: icmp_seq=2669 ttl=64 time=54.2 ms 64 bytes from 192.168.16.77: icmp_seq=2670 ttl=64 time=2.35 ms If I find some time I'll try rerunning the same test from windows. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2058752 Title: ath11k high jitter and packet loss when operating in 802.11ax mode Status in linux package in Ubuntu: New Bug description: On 6.5.0-26-generic, my QCNFA765 cannot really operate in 802.11ax mode.

Well, that was a pleasant surprise! On 6.8.0-11 the problem seems to be
