It might be worth noting that the same problem has now appeared on Win10Īfter the April 2018 update. Number of lost packets, stability seems a bit better. It is hard to tell for sure, but even though there still is a considerable (ce397d215ccd07 b8ae3f71db689ae db85d56ab40) and the problem seems to persist:ħ399 packets transmitted, 5704 received, 22% packet loss, time 7446041ms I have tried the latest firmware on v4.18-rc1 M.:ct3: cvrToBeFilledBy O.E.M.:ĭmi.product.family: To Be Filled By O.E.M.ĭmi.product.

It seems that restarting the NetworkManager service helps for a bit, but after a while the problem resurfaces. I have disabled the WiFi power saving (changed from 2 to 3) but that didn't fix the problem. Under the very same conditions, the packet loss on Windows is exactly 0 (and the RTT never gets above 500ms). a phone), the packet loss can get up to 90%. But when some objects are placed near the antenna (e.g. With the antenna placed in an obstacle-free area, some ping packets are occasionally lost. On Ubuntu 18.04, the card's behaviour seems very correlated to the signal strength and exhibits a threshold phenomenon. 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). 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 WiFi adapter Gigabyte GC-WB867D-I is quite unstable on Ubuntu 18.04.
