Public bug reported:
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
