    A while back I installed a free CM8200 modem from Cox(no rental).  I have been trying since then, of and on, to access settings information from the modem.  I tried Reset and Refresh with no luck.  I have no information from COX as to how to see the settings. Google 192.168.100.1 results in TIMEOUT. No trouble getting to my TP-LINK router.

    Everything runs okay, I guess.  I just don’t like not being able to see information that should be available.

      1. Open any Web browser on the computer connected to the CM8200.
      2. Type the default LAN IP address, 192.168.100.1, in the Address bar and then press Enter.
      The CM8200 Status screen displays.

      That is EXACTLY what does nothing.

        Do you have active extensions in the browser that could potentially block the connection?
        noscript etc.. I suggest disabling any extensions like this to see if you can access the router settings page.

        Run ipconfig and check router’s default gateway address.

        Try unscrewing the modem coax cable, then directly connect to the modem with an Ethernet cable, and then attempt a connection the address 192.168.100.1

        Alternately sometimes browsers won’t render a site pages even without extensions.

      <i>192.168.0.1 access the TP-LINK router with no problem. </i>

      The modem I had previously gave me no trouble getting into its internals.

      I ran ipconfig /all and it shows the router address only.

      IPCONFIG does not show a “Default Gateway”?  That’s the address you would type into your browser.    Routers will differ, but mine is 192.168.1.1 .

        Mine shows default gateway within ipconfig…..for what thats worth. I use the ip to set passwords, wireless settings etc. If all else fails do a search for your router but it’s odd ipconfig doesn’t reveal the gateway and a bunch of other stuff too!

      This started happening to me after updating Firefox – recently.  Still works in Chrome current version in the same scenario, after accepting the security exception.

      For some reason Firefox is no longer even trying to connect through the gateway to the modem on the WAN side.

      Beware. Sometimes entering IP address of router does not work, because, browser tries to connect via HTTPS, which your modem does not have.
      Try to check, if there is https before IP. Alternatively try to correct it by deleting “s”.
      Use HTTP protocol when acessing your router please. Also try different browser like iexplorer.

      Where is the security exception referenced by NETDEF?  I can’t locate it in Privacy and Security?
      Chrome removes all but the URL. How can I be sure it is looking for HTTP and not HTTPS?

      Looking at Cox Arris CM8200 online, it is only a modem, not a modem/router.

      Have you tried bypassing your router?  Connect your PC Ethernet cable directly to Port 1 on the modem and try entering the IP address.

      You need to look for the ROUTERs gateway, which ordinarily would be the ‘Modem’ and visit that!

      You can always connect directly to the modem if you really want to poke around its settings. This should work even with the modem live, there is no need to unscrew the coax first.

      The modem is likely to have two things of interest: an event log and a count of packets sent/received and the errors in transmission.

      You are *not* looking for your default gateway IP address. That advice comes from sloppy use of terminology. You also do not want to look for the default gateway of the router. That is a computer run by your ISP.

      The security exception referenced by NETDEF assumes the modem supports HTTPS, this is unlikely.

      Best guess is to do
      http://192.168.100.1
      rather than just
      192.168.100.1

      because browsers may have switched from defaulting to HTTP to defaulting to HTTPS. I would bet this works.

      Maybe the router is blocking access to the modem. Unlikely but possible. Try a trace route to the modem IP address.

      The http://192.168.100.1/ does a timeout. I am assuming Chrome is allowing the HTTP.

      I did a tracert 192.168.100.1 and it showed 192.168.0.1 and 192.168.100.1.

      Doing it for the router only showed that as that is the first leg in the search.

      I’m using Firefox fully updated and on my Motorola Modem/Router if I enter http://192.168.0.1 it will truncate the http:// and leave just 192.168.0.1 in the address bar and connect directly to the router login page.  Edge reacts exactly the same way.

      When you are connecting to the modem from the LAN side it does not need nor use http.  Just put the numerical address in the address bar and hit Enter.

      My router and modem are separate. I just tried a reboot with no change.  The modem came from COX for free.  I assume it is to allow DOCSIS 3.1.

      I thought about a reset, but because it came from COX and IS NOT supported by ARRIS, I don’t know what COX may have done to the settings. This is why I am trying to look into the settings. CURIOSITY only at this time.

      I understand that some ISPs disable these modem pages on their modems. I don’t know if COX does this to the 8200. You may get some insight by inquiring at https://www.dslreports.com/forum/coxhsi .

      A direct connection to the modem is not required, since the modem and router have distinct addresses. I can look at my modem, router, and an AP with everything connected.

      Michael could you please explain that. The router IME looks to the modem for a gateway and that is the modem.

      Reset did nothing.  dslreports was unable to help. If Cox has turned off access to the firmware, I wonder if it is software.  If software, I wonder if anyone has worked around it?

      As I mentioned, the front panel only has the receive light on as blue(DOCSIS 3.1). Online is indicated by a flashing light where the router and modem are connected in the back.  Is it possible Windows 7 Pro 64bit needs a setting for the DOCSIS 3.1 modem setting(Yes I am reaching).

        1 – OK concerning DSLReports. I’ve done a thorough search there, and there is only one mention of non-access that I find: two posts starting at [2017-May-8 9:46 pm]; and that problem resolved itself. My suggestion on non-access is based from another DSLR forum, concerning different ISPs and modems.

        2 – I think that your modem is sick (but masking it won’t help [grin]).

        A while back I installed a free CM8200 modem from Cox(no rental).

        From reading others’ threads on DSLR, you’ll need to get a replacement. Contact Cox for instructions.

        3 – Thee is NO computer setting – OS or browser – that can affect the display of the modem info.

      If you have another power adapter of similar or higher specs give that a shot. I’ve had similar issues with many electronics with a poorly functioning power supply.
