CM600 - Admin Page Not Responding

[vailAZ]

The administrative page at 192.168.100.1 of my CM600 cable modem has mysteriously stopped responding.  I've tried several browsers and there's simply no response anymore -- no login request, nothing.  I can see that 192.168.100.1 is alive by pinging it, however.  Tried powering the modem off and back on again -- same results.  Any suggestions?

As a follow-up -- a hard reset solved the problem.  Thanks to all for the advice.

Possibly try a hard reset - pushing the reset button in for about 7 seconds.

What ISP?  I'd heard of some disabling access to administrative interface on other modems.

My ISP is Cox. I've had them for years, and have never known them to disable the status interface.  Going to try a hard reset when I get back home in a couple of days.

I have Cox as well, got a CM600 two weeks ago.    Have you tried accessing http://192.168.100.1 from a cell phone or tablet?   Just to make sure its not a firewall or A/V software on the computer blocking it.

Yep -- tried it from multiple computers in the house, as well as a tablet and phone.  192.168.100.1 is active and pingable, but refuses to respond otherwise.  It worked fine a few days ago, and then just suddenly quit working.

What about plugging ethernet cable from a computer right into the modem?  Maybe something with router is preventing access.

Good suggestion -- it's been tried, no effect.  I'm hoping a hard reset on the modem will fix the issue, but it will be a couple of days before I'm back home from a business trip to give it a try. 

The modem was bought new in early November, so if this is some sort of failure I suppose Netgear would step up to the plate and exchange it.

Hello VailAZ

If you believe that the modem is defective then you will need to contact support as they can help with a exchange if it is needed.
