Since a few days ago my laptop is suddenly slower and no longer connecting to my 5G wireless router band. It is instead choosing to connect to 2.4 G band, which is too slow for me. I don't know if after the Microsoft Windows 11 upgrade, there is a new driver I need to install or something but I do need help. I would sincerely appreciate your assistance.
Thank you in advance.

Your notebook is not capable of connecting to the 5 G Wi-Fi band.
It comes with a single band (2.4 GHz only) Realtek RTL8723DE Wi-Fi adapter.
Below is the link to the specs on that model Wi-Fi adapter.
If you are interested, you can replace the RTL8723DE Wi-Fi adapter with this dual band AC model:
Realtek RTL8821CE 802.11 ac 1x1 Wi-Fi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.
The card has a maximum throughput of 433 MBPS on the 5.0 GHz Wi-Fi band with an AC router and an excellent signal.
You can find this model on eBay, or Ali Express.
I see some Intel 3165 cards listed on the eBay listings, so don't buy those.
On the Ali Express listings, make sure the card has the HP Part # of 915620-001.
Below is the link to the service manual, where you can find the Wi-Fi card removal and replacement procedure.

Thanks for such prompt and detailed reply to my support inquiry. The card replacement seems like a bit of a complicated of process to me. Hence I was wondering if something this simple might work too?
