While using Ubuntu 16.04(Kernel version updated to 4.14 where we started to have support to this chipset) or both 18.04 beta 1 and final version i found a problem: 1º when i boot all this versions with the kernel version >= 4.14, i found out that the driver is instaled and she is detected in the network manager.Anyway, when i used she won´t work and in few secconds later will shutdown. When i go to the wifi settings i can´t find networks! 2º I use modprobe so that i can manipulate my drivers/modules and i can start to work with my wifi card: -> modprobe -rv r8822be -> modprobe -v r8822be aspm=0 The problem is that when i connect to a 5ghz frequency router, i have very slow download speed 8 mbps max (Usually my speed is approximately 200/210 mbps in wifi mode).In the outher hand when i connect to a 2.4ghz frequency router it works fine!
