  Realtek r8822be kernel module does not negotiate 802.11ac connection

Status in linux package in Ubuntu:

Bug description:
  I have an HP Omen laptop with dual boot installed.  It has the Realtek
  8822BE wireless chip set installed, which when running Windows 10
  works as intended, i.e., it establishes an 802.11ac connection with my
  wireless router with speeds up to 866 mbps. However when running my
  Linux environment, Ubuntu Studio, the connection speed is established
  as 802.11n, and is limited to 300 mbps.

  I also see the following message in my logs which might be related to
  this issue:

  wlo1: capabilities/regulatory prevented using AP HT/VHT configuration,

  Please advise if additional information is needed. Per the bug
  reporting guidelines also see below.
