I have a Webstar Cable Modem with RoadRunner, and I'm having issues with downloads being interrupted mid-stream. If I use my Download Accelerator program, it shows a sudden decrease in transfer rate (right down to zero) and than after a brief delay, it starts resuming the download (if resume is supported.) If I don't use the download accelerator or resume is not supported, the download just time outs and I have to start over again. At first I thought it might have been the router but the problem occurs even if I bypass the router and use the Ethernet connection directly. Perhaps the cable company is doing some kind of throttling or maybe it's just a problem with the modem. Any suggestions besides calling the cable company?
