I have a 2019 mbp 16" 5600m i9 9980hk, I am having an issue where my Wi-Fi is running in 802.11a, it doesn't even say 802.11ac is supported/available Radio types supported : 802.11a 802.11n 802.11g 802.11b
I reverted the Broadband driver to 101.10.152.10 as people recommended to online saying the newer versions stuffed it up.
It runs in 802.11AC on macOS
MacBook Pro 16″, macOS 15.1

Where are you seeing this informatIon?

This is Not an issue that has ever been reported here.
Don't randomly-posted advice from strangers or AI recommendations unless you are certain they are based on reliable sources, or from an environment (like this one) where BAD ADVICE is quickly challenged by others who know better.
Restore your MacOS to what was running before.
If your Wi-Fi only runs as 802.11a, this is a ROUTER issue and not a Mac issue. The Router sets the operating rules. MacBook Pro 16-in intel is perfectly capable of 802.11 ac rules, but your ROUTER must transmit using those rules.
if you can, I suggest you connect using Ethernet. It is simple and straightforward.
The software to support Wi-Fi inside a virtual machine (likely including bootcamp) is unbelievably complex, and results tends to not provide very good results.
Sorry my mistake I didn’t seem to mention the error was in boot camp.
I am getting the supported radio channel info by running this in the command prompt.
netsh wlan show drivers
I have tried updating boot camp services to the latest version via boot camp app on macOS download boot camp support software option, it still doesn’t show 802.11ac, It DOES on macOS though so I can’t see it being a router issue.
here is an extract of a system report
Option-Apple Menu System informations > Network > Wi-Fi
from a really OLD 2009 Mac Pro with its original wifi card. it supports up to 802.11n, provided the Router can transmit in that mode.
your Mac supports MUCH more.
