Recently after re-installing windows 10 onto a computer, the Internet became extremely slow. Using a speed test on other computers, the down would be 100+ mbps with 10+ mbps upload. On the slow computer, the down would be ~4 mbps with ~1 mbps up. I've tried updating the wireless card drivers and even replaced it, but the issue still remains. Any help would be appreciated.
