    ISP sees modem offline, but connection works

    Might anyone have an idea as to why my cable ISP tells me they see my modem as being offline even though my connection works? They've told me this twice now when I've called in for tech support since getting this modem (which is on the ISP's approved modem list) back in January. I recall that even when I was getting it provisioned, the tech said they couldn't see it online even though the connection was live.

    We've been having low downstream speeds for months now (can't get higher than ~35 Mbps on an "up to" 200 Mbps plan, both on speed tests and in real-world downloads), so I was thinking perhaps this "offline modem" issue might be the culprit? They assure me we are not being throttled, but connecting through a VPN gets us 100 Mbps+ down, and I'm told that's a sign that throttling IS happening.
