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. 1.The WiFi adapter Gigabyte GC-WB867D-I is quite unstable on Ubuntu 18.04. 1.0) Bluetooth Driver Gigabyte GC-WB867D (rev. 1.0) Broadcom Bluetooth Driver GC-WB867D (rev.
