    Question: Is my old Motorola Surfboard SB5100 Modem the problem?
    The problem: When browsing, if I choose to view a video clip on some sites, my PCACTIVITY led starts to flash rapidly and then persists. I understand this means that data is being exchanged. The problem is that after I have stopped viewing the clip, the rapid flashing continues for a long while - even if I do no further browsing. If I do a speedtest during the continuing flashing, I get poor results compared with a test when the led flashes only occasionally. Is my modem unable to restore itself to the relatively quiescent state? Should I replace it?

    The ISP tested my cable line, connections, and signal strength. All are OK.

    No one has replied; so maybe I don't have a problem with my modem, computer, or iSP.

    Maybe the problem is website dependent. I am towards that answer, because some websites from which I watch flash video clips, youtube.com, for example, seem to end the data exchanges when the clip has ended. The PCACTIVITY led stops the rapid flashing. Other sites seem to continue the data "handshaking" even after I leave the website. That is my conclusion. The answer, then, is to avoid the websites that don't let go. I don't know if this makes any technical sense, but lacking any suggestions from TSG I'll be content with my own answer.

    I hope this helps someone else who has observed the same condition. I am marking this "Solved."
