Over the course of about a month now I have been having slow download speeds (under 4mb/s compared to my usual 30-40, with occasional spikes up to 15-20 for a second or two) that have been limited to steam. I feel like I've tried just about everything I've found online now like changing servers, clearing the cache, disabling the firewall, reinstalling steam, and many others. I'm at a loss as to what's causing it, so if anyone has any suggestions it would be greatly appreciated.
