[Bug 1772154] Re: Unstable WiFi adapter Gigabyte GC-WB867D-I
Most people don't have the hardware you have, so usually it's on your own. There are a few ways to try: 1. latest kernel from https://kernel.ubuntu.com/~kernel-ppa/mainline/ 2. latest firmware from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/ 3. backport-iwlwifi dkms from https://launchpad.net/~vicamo/+archive/ubuntu/backport-iwlwifi-dkms -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772154 Title: Unstable WiFi adapter Gigabyte GC-WB867D-I To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1772154/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 1772154] Re: Unstable WiFi adapter Gigabyte GC-WB867D-I
I have tried the latest firmware on v4.18-rc1 (ce397d215ccd07b8ae3f71db689aedb85d56ab40) and the problem seems to persist: 7399 packets transmitted, 5704 received, 22% packet loss, time 7446041ms rtt min/avg/max/mdev = 1.431/5.948/1057.709/36.507 ms, pipe 2 It is hard to tell for sure, but even though there still is a considerable number of lost packets, stability seems a bit better. It might be worth noting that the same problem has now appeared on Win10 after the April 2018 update. The latest Intel 8265 from the 14th of June doesn't seem to do any good (microcode update?). Please advise on how to proceed. Thanks. Best regards, Gabriele On Fri, 8 Jun 2018 at 20:01, Kai-Heng Feng wrote: > There are lots of new commits in iwlwifi since v4.17-rc6.

apport information ** Tags added: apport-collected ** Description changed: The WiFi adapter Gigabyte GC-WB867D-I is quite unstable on Ubuntu 18.04. I do not have data relative to previous versions of Ubuntu since this PCIe card is part of a new build that has had 18.04 as the first installed version. The reason why I can point the finger at the Linux kernel is that the card seems to work reliably well on Windows 10 (no packet loss when pinging the local router). On Ubuntu 18.04, the card's behaviour seems very correlated to the signal strength and exhibits a threshold phenomenon. With the antenna placed in an obstacle-free area, some ping packets are occasionally lost. But when some objects are placed near the antenna (e.g. a phone), the packet loss can get up to 90%. Under the very same conditions, the packet loss on Windows is exactly 0 (and the RTT never gets above 500ms). I have disabled the WiFi power saving (changed from 2 to 3) but that didn't fix the problem. It seems that restarting the NetworkManager service helps for a bit, but after a while the problem resurfaces. The card in question has onboard USB Bluetooth and is pretty much an M.2 to PCIe x1 adapter for an Intel Wifi adapter.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 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.
