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.
