C6300 Frequent disconnects
Seems to be a common topic here, but don't think I've seen a definitive answer so gonna try again. Purchased a C6300 because it was (seemingly) the best modem / router out there supported by Comc...
Sadly I have been waiting 2 + years for an update to fix the problem with connections dropping but the problem still exists.
Please make sure that when you get a new modem to contact your ISP remotely configure and provision it. This is the most common fix. Further troubleshooting is needed if the problems persist of course.
If you don't do this you will not be experiencing lag and disconnects, so if you are reading this and having this trouble.This is the first thing I would address. It could also be an issue with the line itself, or a splitter on the line causing interferrence. So if that is the case then your ISP is going to have to come out and inspect the lines and replace them if needed.
Check your diagnostic logs for T3 and T4 timeouts. If you find them then most likely the issue is what I mentioned above.
The C6300 is great, but I recommend getting the C7000 if you have Xfinity.
I appreciate that you're trying to help, but there are many people now who have had similar problems with the C6300, and doing the basic troubleshooting steps above has already been shown to not work, both in this thread and others.
I'm sorry to say this is a bad modem router. Netgear needs to pull it.
Agreed. C6300 is garbage. When I was using it, they came out to "fix" it multiple times. No success. I'm sure the tech reprovisioned during his many visits. When I switched to the Cisco modem, I have had zero problems with wifi dropping and random reboots.

So NETthisGEAR, what is the basis for your statement "The C6300 is great"? This thread is full of a very consistent message that it is unreliable. I have proved it beyond doubt by inserting a Gargoyle router into my network. Use the C6300 for routing and it constantantly fails, use the Gargoyle and it is perfect.
I fail to see any basis for saying the C6300 is great!
The majority of the time the issue with disconnects is the customer not contacting their ISP. You can go to and modem/router page and find people complaining of disconnects, it's by far the most common and easily fixable probem(in most cases). And if not all you have to do is contact netgear and have them help or send a replacement.
I understand your point on why I said it's great in a thread where it's disconnected, but you can go to any modem and it will have the same topic. People aren't going to post when things are going well, they only post when there are issues..That is what is going to happen. The C6300 is one of NETGEAR's highest performance/specced modem/routers, aside from the C7000. So my point was I'd get the C7000 first if possible.
NETthisGEAR, what is your basis for that ridiculous claim that "The majority of the time the issue with disconnects is the customer not contacting their ISP"? Exactly what is their ISP fixing? There are so few variables that the standard settings are going to work out of the box most times. And if tehy don't, the symptoms are likely to be a lot more obvious that dropouts.
How can I make my situation any clearer? It is a routing issue. I can put the C6300 into bridge mode and put a proper router behind it and it is perfect. No dropouts at all. I put the C6300 back into router mode and constant dropouts. Put it back into bridge mode and the Gargoyle router, perfect. There is no question whatsoever that the C6300 is having problems. And clearly this is not an ISP fixable issue, since it is fixed by using a router that actually works!
The device is a piece of junk and everybody know its. Have a look on the Telstra support website and see how many of their customers are contacting their ISP. And have a look at the responses of the Telstra support people. The only person who is going to be calling this a great modem/router has to be a Netgear shill!
