Slow wifi on Bootcamp after latest Windows update

WiFi used to be 300-400mb on bootcamp till last week when Windows applied it's usual round of updates. Now I'm back to sluggish 30Mb speed (either that or fast.com is lying to me).

It's got to be a windows driver issue since I get the 400mb+ speed when I'm using the iMAC. Windows doesn't help since it doesn't give me the broadcom model number and the broadcom site itself is atrocious trying to find the right drivers.

Is there an updated broadcom driver available (my driver is April 2020) via bootcamp update or another fix I can apply to get back to the old speed ?.
