Cannot Connect to default gateway with C6300 after factory reset
Ive done a lot of searching around on this forum and online, but I cannot find a solution. I was port forwarding on my modem+router c6300, connecting through the address 192.168.0.1. I saved my r...
tftp won't work on that device.
I don't want to sound stupid since you've already tried a lot but 3 things to try.
1. more than 1 users I've seen factory reset incorrectly. Make sure to push and hold while powered on for up to 15 seconds. The lights should change.
2. You can always try a 30-30-30 reset. Push and hold reset while powered on for 30 seconds, unplug it while still holding reset for 30 seconds, plug it back in while still holding reset for 30 seconds
3. Try the reset option from #1 but disconnect the coax from the modem.
Again, you might have tried these but always worth a shot.
Also, the C6300 is on spectrums minimally approved list. Not sure what speeds you're paying for but it might be getting close to start checking into an upgrade to a docsis 3.1 device if the speeds you pay for are higher than that 300mbps. An idea is that spectrum might still be giving users modems without charging a fee. If they are, they tend to be the multi-gig modems. Then you'd only need a router. Might be a pretty solid performance upgrade
Alright, I walked through the steps recommended, and nothing has really changed. I almost had a moment after checking the network request through fiddler, as tells me the request returns a 401 Unauthorized, and realized the normal alert/input box for the username and password would usually appear.
I've compiled a beautiful collage into one picture in paint, since only one attachment is allowed.
First i showed the request as it shows in the Firefox dev network tab, giving the INVALID_HEADER_VALUE error, and beside it is the headers tab for the request, along with the request and response for it (which show as blank).
Then going into Fiddler, i requested and show the Request/Response Headers there, showing a 401 response.
At the bottom, I did the same thing as your previous screenshot, as I installed Chrome completely fresh, went to about:blank, and then went to 192.168.0.1, showing the network tab with the same settings as suggested. Response headers is empty, request headers the same as shown in Firefox, with nothing in the console, other than that it navigated to the error page for Chrome.
If there is any way to get the firmware, I'm open to trying TFTP, but I currently dont have a firmware backup myself. Everything I've found online, including the model's download page, say that firmware updates come directly from the ISP, but Spectrum basically told me they couldnt do anything cause its a third party modem, and not theirs. Im skeptical of this, so maybe I should just yell at them a little bit, and tell them to reactivate my modem, and hopefully the firmware will update?
(The picture is being attached as a file as well, since the image on the post itself is pretty awful)
