Alright so here's my conundrum. I have Metrocast cable on a spur line for my ISP. Service is sketchy and there is no alternative options (not even dial-up any more). I am no networking guru so speak as much English as possible.
this is what I get from magical speedtest.net
we run 2-3 computers playing ET/World of tanks/World of warcraft generally simultaneously. generally not problematic. however whenever I run Bittorrent every computer on the network will be max ping 999 death. not just the machine with Bittorrent on it. now I hear the port forwarding, I hear the cap the upload rate what I don't know is how to go about doing that.
we are currently running a Dlink (I believe DIR-825 by what I find on the router setup page) and the Modem supplied by Metrocast. (where I have no info.) I wish to avoid getting new hardware as I currently am broke, but suggestions for upgrades will be appreciated for future reference.
