Downloads Interruted with Cable Modem

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?

MTU testing, and continuous keep alive.

Also try using a different download program.

If nothting helps, then it is probably your provider, although you might try resetting your modem also.

try it on a different computer, and see if it still happens.

also see for info on utilities to check out your issue.

I hope this helps !

I've already tired that - the same problem occurs no matter which computer I use.  I'm familiar with; do you have a suggestion for a particular tool that I should use?
Can you supply what solved your problem, or identified the issue ?

Thanks !

I called the Cable company and I'm not getting a full signal - they're working on it.  So it appears to be a provider issue.  Thanks for the assist.
