I'm having a strange wireless bandwidth throttling issue that I hope someone on here might be able to help me solve. For some reason, all my downloads (for the most part) are no longer getting higher than 300kbps. I have a wireless n router/cable modem combo along with a cable internet subscription that nets me 18Mbps down and 10Mbps up. I've tested my connection multiple times throughout the day across multiple devices to ensure that I am indeed receiving the throughput I'm paying for. So I know the problem is not on my cable company's end.
However, on my mac, whenever I download a file from a known high speed server (that should max out my connection) my maximum download speed hovers around 300kbps instead of something like 1.6Mbps where it should be. I know it's my computer that's the issue because if I attempt to download the same file off my roommates pc on the exact same wireless network connection, he gets the full 1.6Mbps download speed while mine just stalls at 300k max or just around that speed. The really weird thing is that when I do internet speedtests (e.g. http://www.speedtest.net) in the various browsers on my mac, those report my full available speed (18Mbps down). The issue only appears on downloads, and it happens in every single browser I have installed. More curiously, these speed cap issues don't appear in my torrent program or within the steam application when downloading games, but they do appear in my browsers or through jdownloader download manager standalone application.
It's as if my connection on my mac is capping itself out for some reason in browsers and download managers. I've disabled all proxies, any other programs that could be sucking up bandwidth (crashplan etc.), and all my browser extensions, but no matter what I still have these capped out download speeds in every browser. Any idea what I could do to troubleshoot this?
I'm a fairly savvy mac user (10+ years), but this is baffling me. The only thing I can think of that makes my connection different from my roommate's is that I have changed my dns servers. Other than that, I can't figure out why my speeds are capping out when his download of the exact same link connected to the same wireless network is maxed out. Please help.
