I was recently upgraded to a 16/2Mb line from comcast from my old 6/2Mb line. with my old connection, I had a sustained download speed of about 1000KB/s. I am connected directly to the modem, and when running a speedtest I see that i have a speed of about 16000kbs ~ or so. but when downloading a file I still see speeds of the same 1000kb/s. Wouldnt I expect a much higher download speed with my new 16/2Mb line?
