It's possible but I still suspect either your cable feed or the modem
itself.

I use the same model cable modem and I get the same ping failure when my
cable modem signals go bad or if I disconnect my cable feed from the modem,
not the Ethernet cable, and the ping fails with the same message as yours.

I think you need to read the log file that your cable modem has in it to see
if you are getting Sync loss/recovery messages or FEC LOCK recovery
messages.

Check the log prior to having a problem and after you have had one and see
if the log entries are increasing. My log file can go quite a few days with
out new entries when the cable signal is stable.

For a while every time Comcast tested what used to be called the Emergency
broadcast system on all our TV channels my cable modem would go nuts until
they ended the test. I don't know what the did to fix it but it the last
few tests my internet feed stayed up.

Here is my log back to 12/04. Nothing since 12/06.

031206085246 5-Warning F506.1 Bridge Multicast Aging. Failed to get
mbuf to Send Igmp Request.
031204205014 7-Information F504.1 Bridge Ethernet Hook. Failed to
learn CPE MAC Address.
031204205014 4-Error F507.5 MAC Filters. Add MAC Address can't add
entry. Table is full.

The last one about MAC table full can be corrected by powering down the
modem for a few minutes. You know, maybe you should just buy a modem
and solve the entire modem question for $50?
