For the last week or so, my cable modem has been restarting constantly. The only thing that has changed is Comcast took over from Insight. What can I do to fix this?

providing of course that you lease the modem from your provider.

If you own the modem, call Comcast and speak with Tech Support in order to get some help and advice determining whether or not settings need to be changed, and/or Comcast supports your modem, and/or a host of other things that probably only Comcast can advise you.

Also, do you periodically 'reboot' your modem and router (if you use one). If not, shut things down, unplug and this does mean unplug the modem and router for a minute or two before plugging back in. These devices build up a minor electrical charge that interferes with their proper functioning at some point. I reboot my modem and router monthly.

I have never heard of rebooting the modem/router monthly.

Got a site that talks about that?

Thanks,

These devices do not build up a minor electrical charge.

The issue has to do with memory corruption. Internal dns tables, arp cache tables, forwarding databases and so forth get errors over time.

Most soho routers do not contain code which has been tested very well, so issues like memory leaks, memory heap corruption, stuck or crashed processes are not out of the question.
