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...
I just finished checking for new updates for the router, it is current. I tried several soft resets and let the router try to fix the wifi on its own. I also tried the hard reset button once, with no success, then finally unplugged the DC power supply and that did the trick. This is a rather frequent series of events, and it comes in bunches. I can rock along just fine for a month or two, then whammo - I have lots of trouble for a week or two. This is probably the third or fourth spat of problems since I purchased the modem last May. I am using more devices - just added a Nest, a Google Home, a Pixel phone and a 4th Chromecast device. However, I expected this router to be up to the task.
Sadly I have been waiting 2 + years for an update to fix the problem with connections dropping but the problem still exists.
Hello Ssamarron
Have you ran speed test and packet loss tests to see if you can find why the lag is happening you may also want to check the logs of the modem.

Another disgruntled C6300 user!
I read so much about the wireless problems I bought a separate, very expensive access point. Tunrs out the problem is not the WiFi!
I can leave my computer pinging the C6300 from my Mac and it is going via teh new Asus AP, does not miss a beat. After hours of pinging, not a single packet dropped.
At the same time I am pinging various reliable external IPs and regardless of which ones I ping I get around 15% packet loss. So it seems resonable to assume that the connection between my Mac and the C6300 are bulletproof, and the frequent dropouts are between it and the rest of the network.
Given how many others are reporting similar issues, when will Netgear finally acknowledge that this device is inherently faulty and then do something to correct it?
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.
