how to connect to my modem through browser

Question

--AC3200 WiFi Cable Modem Router, model C7800
&nbsp; &nbsp; &nbsp; above taken directly from the manual title
It is ethernet wired to my computer. In a browser, I enter the URL, 192.168.0.1 (as per the manual) with id of admin and password, password, again as per the manual for the default, and I get an error message, so I cannot get into the software on the modem. Why is this happening?

&nbsp;&nbsp; Were you not even _slightly_ tempted to reveal what this "an errormessage" actually said?

&nbsp;&nbsp; It might be easier for the non-psychics in your audience to determinethat, if the text of that "an error message" were accessible to them.

&nbsp;
&nbsp;&nbsp; Look for "Factory Settings" (or "reset") in that "the manual"?

I'm sorry. I really didn't mean to be cryptic. There really was no message. The signin just kept repeating and I know it was connecting since it said "NETGEAR C7800". I did check the section of factory settings and it suggested using the paper clip in the reset hole. I did that and it did seem to reset and after the bootup, I tried the signin and got the same result. So I am stumped.

OK, this time after several attempts, I got a screen asking for the modem serial number. I entered it and then it asks me 2 security questions.....my first school and best friend's name. Where did it get these questions and how would a brand new machine know the answers? I answered as best I could (not having previously saved this information) and then got a message, "The information you entered does not match what is saved on the router. Please enter it again."
&nbsp;
How could the router have any information saved about me? I just bought and installed the thing!!

OK, here is another bit of information I found. The MAC address shown on the bottom of the modem ends in 'C8'. When I notified my provider that I had a new modem/router, that was the MAC address I gave them. I've been doing a little searching and found the command 'arp -a' which yields all the items on my network and their IP and MAC addresses. The modem (at 192.168.0.1) shows the same MAC except for the last 2 digits are 'CA'. Could this be the problem? I will call Cox and see what they have in their system

&nbsp;&nbsp; If "admin" and "password" fail, then you might try another reset,perhaps with all the data/signal cables disconnected.&nbsp; A proper resetreally should restore those default credentials.

&nbsp;
&nbsp;&nbsp; That's the password recovery scheme.&nbsp; From what I've read, this wasvery poorly implemented, including asking questions for which no correctanswers were ever supplied.

&nbsp;&nbsp; It couldn't.&nbsp; Welcome to Netgear modem/router firmware quality.
&nbsp;
&nbsp;&nbsp; If you get desperate, you might ask your ISP if then can flush itsbrain and reload firmware afresh,

&nbsp;&nbsp; You wish.&nbsp; Every interface on the C7800 has its own MAC address. That includes the cable/WAN interface, which is what interests your ISP(and should be what's obvious on the label), and also the LAN Ethernetinterface, which is what a wired client device will see.&nbsp; Similarly, thewireless interface may have its own MAC address.&nbsp; But if your ISP wasdemanding the wrong one, then your connection to the ISP would be yoursymptom.&nbsp; You should be able to get logged into C7800 using your browsereven if you're completely disconnected from your ISP.
&nbsp;
&nbsp;&nbsp; Which browser are you using (on which type or computer/device)?&nbsp; Haveyou tried a different browser?&nbsp; (After an effective settings reset, ofcourse.)
