Hi,

If it's possible I will suggest that you can use the new driver "rtw88" being
reviewed now. rtw88 is better supported by Realtek and has significant
improvement in contrast to r8822be. And also it is aim to better support
802.11ac series ICs, so it may help resolve your problem about 802.11ac
connection speeds.
Thanks!
