I can't log into my MODEM. I was able to set it up once using the default gateway IP address about a week ago. Then my kids unplugged it and something changed when plugged back in. When I try to log into my modem using the IP address it just gives me a web page saying its unable to connect. My internet works fine, I am able to ping the address and it replies with no data loss, I can trace route to it, I can release and renew the IP address DHCP server. I am just unable to bring up the webpage to login. I have turned off my firewall (windows firewall). I am just at a loss on what to try next. I want to turn on my Wi-Fi and such, essentially administer my router for my computer. I have did a hard reset, held the button for the recommended 15 seconds with both power on and power off but no change. The modem is a Technicolor TC8717T.

Edit: I ran the Microsoft Internet troubleshooter and I used the IP address instead of the domain name and it said "The remote device or resource won't accept the connection". So it seems something within the router is refusing to let me connect, but still acting in the MODEM role.

Click on Start menu
Type in cmd
Right click on cmd in list and select run as administrator
Once you are at command promt type the following exactly as typed
ipconfig /all > network_info.txt
This creates the file, network_info.txt, in the current folder
Upload the file to your next reply

The TC8717T is a modem/router combination unit. According to your ipconfig /all shown in the recent post it is operating as a modem only, completely bypassing the router part. Whether you did something to put it into that mode or whether the device is defective I do not know.

If it's yours I advise trying to reset it to factory defaults.

If it's your ISP's I advise contacting them for help.

I own it, I bought one because I was tired of paying the 17 dollars a month for rental. Is it possible my ISP was able to disable the router portion? Just for my knowledge, how can you tell its operating as a Modem only? I suspected this when I tried to connect my laptop to the other ports and it wouldn't let me have internet access.

First clue was your IPv4 address is Public. It would be, or should be, Private if assigned by a router.

Second clue was your IPv6 address is Public. And, being a Moderator here, I can see that it is the one you were using to post.

Perhaps. I've used my own modem and router (separate units) for all but the first couple months of the 15 years I've had Mediacom cable. However, my neighbor has been renting a modem from them and using her own router. A year or two ago Mediacom sent her a Technicolor modem/router saying that their imminent upgrade would make the older modem obsolete, and started charging her for "Wi-Fi" in addition to the modem charge. She's not exactly a tech guru, so I was acting as her tech support. She called them to say she did not want the Wi-Fi, but wanted to use her own router. They claimed to do something over the internet and told her the Wi-Fi was disabled. It wasn't (it was using the same channel as her router), so I logged into it and disabled the wireless.

The point of that rambling barely relevant paragraph is that Mediacom has the ability to access the modem/router and make changes. If you recently made the cost saving change somebody there could have misunderstood and thought that you were rejecting the rental of the router part but still renting the modem. Painful as it is you probably need to call them to see if they can re-enable the modem part. Also check your bill for the next couple months to make sure you've not still paying part of that $17.

I have Mediacomm as well. I was thinking at this point I should probably call them and see if they did something to my configuration. I know I told them I wanted the MoCa disabled and I'm not sure if this may have been a side effect. My technician that took it I believe said that it was only the Moca that would be affected but the lady I spoke to at Mediacomm may have misunderstood. The tech also said this is the same exact router they use for some installations, so it might be possible.

Thank you both for helping, I'm just glad to have the help, for three days I've been bashing my head against a wall on whats going on. I "piddle" in networking as a system administrator for aircraft control and I work with Unix. I have taken courses in NET+ and have never come across this before. But the NET+ was back in 2006, before MoCa and other items, and the STARS (Standard Terminal Automation Replacement System), is based on some old Sun Solaris networking, nothing like my home computer lol.

MoCa - Mutimedia over Coax, but it is basically Ethernet over Cable. I use it on all my Tivos and it works great

I believe, and don't hold me to this, but my technician said you can have MoCa wireless, so it will broadcast and if you don't have these little connectors(such as the one attached to my router/modem) they can interfere with your MoCa devices, especially if another house isn't terminated properly. So I also have this little item, looks like an attenuator that is plugged into my Modem/router for filtering.

Yes, that is correct the frequency can be intercepted if not filtered correctly
