Running a clean install of Windows 10 on a 2013 Retina Macbook Pro via Bootcamp.
Wireless network card: Broadcom 802.11ac Network Adapter


As the day wears on my internet connection (ONLY via my win 10 laptop) gets slower and slower until I simply have to restart the win 10 OS to restore "normal" internet speeds.
Own Troubleshooting

It is NOT my local network because all the (many) other devices are fine. It seems to occur irrespective of which browser I use (Edge or Chrome) Problem relates to wireless network and not ethernet - if I plug in an ethernet cable (without restart) speed is fine again. My wireless card driver says it is up to date
What should I do?
