Re: Gigablast Upload is Terrible Rated - I am having the same issues. My upload on my desktop plugged straight into the modem with gigablast internet is actually at 0.6mbps. 0.6!? Even download speeds are **, 50mbps. With my other plan of 150mbps I was getting 175 down with 10 upload but it was not reliable. Now I pay more and get 50 down and 0.1 up...can never win.
