[Bug 1813372] Re: Realtek r8822be kernel module does not negotiate 802.11ac connection

I have been in touch with several members of the Realtek module
development team. They have provided access to the code for a newer
module, called rtw88, which is currently under review. Based on
comments from Tony Chuang and local tests performed here confirms that
this new module better supports 802.11ac connection speeds than the
previous r8822be driver.

Title:
Realtek r8822be kernel module does not negotiate 802.11ac connection

Status in linux package in Ubuntu:
Confirmed

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,
downgraded

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