I have a Netgear CG814WG v2 cable modem. The internet went out this
morning
and I checked the lights on the modem. The power light comes on, then the
connected ports light up, then all the lights on the modem go on, then
they
all go off. This cycle repeats continuously. I held down the reset button
for 10 seconds but that didn't clear up the problem. I thought it was
weird
that even though I was holding down the reset button, the lights continued
to cycle on and off just like before.

Kinda sounds like continuous reboot or a diagnostic display.

Unplug the coax cable to the CATV network, and try powering on again.
If the flashing lights symptoms are identical, it POSSIBLY means that
you've lost the connection to the CMTS (cable modem termination
system).

Shouldn't the lights remain steady even if there is nothing hooked up to
the
ethernet ports on the modem?

Dunno. Maybe it's in the manual:

or a bit of Googling:

I called the cable company and the tech agreed
with me and said he never heard of that happening before (all the lights
cycling through an on/off pattern). I left it powered off for a few hours
and powered it back on, same thing.

I've seen that, but on an Arris VoIP cable modem. One of the phone
ports had a cable installed that was chewed by a rat and shorted. To
indicate that something was wrong, the front panel lights produced a
light show of diagnostic flashing lights that were eventually decoded
by extensive Googling. I never did find any documentation on what the
flashing lights meant and had to rely on anecdotal guesswork. This
may be more of the same. Unplug everything except the coax cable and
try again.

You might also try asking in the support forum for your cable internet
service provider.

Hi Jeff and everyone else who posted before,

The first thing I tested was the power supply. It read a steady 5 volts dc.
I tried every type of reset. It didn't help. It is now more than 12 hours
since the problem happened. Then it dawned on me, what does the output
sticker on the power supply say? Really? *12* volts dc? I couldn't find
another 12V 1A wall adapter in my box of power adapters. But I do have a 12V
portable jump start car battery with a built in air compressor AND a dc
output jack. I rummaged through my stuff again and found a car cigarette
lighter (do we still call them cigarette lighters?) attachment with a
standard small plug on the other end. I hooked it all up and now it's
working again. My next question is until I find a suitable AC adapter
replacement, can I just keep this 3-in-1 jump starter plugged into the AC
all the time to keep it charged? This is what it looks like though I got it
from Costco many years ago

Thanks for your reply.
