It definitely sounds like some sort of failure, that's for sure. Maybe some kind of heat related one. Unfortunately, the reps are off for the weekend, so the earliest you'll hear from one is Monday.
You can call customer service at 866-347-3292 if you'd rather not wait. They may need to schedule a tech visit, as I don't know if they can send a replacement modem for an older system.
Thank you for contacting us. I apologize for the delay in response. After running diagnostics, it does appear there was a malfunction with your modem. What I would like to do is send you a modem replacement, free of charge. It appears you have been a customer with us for quite some time so we would like to take care of this for you. I will private message you the tracking number once it has been processed. If you would like the modem shipped to a different address, other than the one on file, please send me the updated information in a private message. We are, however, unable to send anything to a PO box.

If you haven't yet talked to Damian via Private Message about the address, you can do so here ("here" is a link).
Hmmm we just got upgraded to the gen 5 yesterday and this morning we have the same problem. Called tech support and they blame the weather. When I asked them to ping my modem they had no idea what I was asking for. Equip is HT2000W . I just wish there was someone that understands tech support in that role.

Are you saying your modem reboots constantly?
I don't think so. It sounds like there's a problem with the modem or the setup. Another subscriber may reply with more info, or the HN staff may run diagnostics on your modem when they're back on Monday.
