C6300 firmware update
I discovered that my R6300 Modem/Router is in need of a firmware update. By all accounts I can not do this myself in the usual fashion and everything I am reading says that my ISP must do the update....
@Belcantor Looks like the issue you have is a minor bug that has been fixed and will be available in next FW release once Comcast has approved it and pushes it out. In the meantime there is a work around you can use to address. So in order to avoid issues with DNS you need to make sure all 3 DNS fields are filled out.
Workaround for C6300 Minor DNS Bug:
1. Log into your C6300
2. Go to Advanced > Setup > Internet Setup
3. On Internet Setup page select Use these DNS Servers.
4. Fill in Primary, Secondary and Tertiary DNS server boxes.
5. For Primary and Secondary DNS use Comcast DNS and for Tertiary either copy the 2nd DNS server to it or use 8.8.8.8 or 8.8.4.4 or 1.1.1.1 or 1.0.0.1. For best performance and security you probably want to use the Cloud Flare DNS 1.1.1.1 or 1.0.0.1
6. Once all the DNS settings have been specified click apply and you should be good to go.
PS: If you need more info on 1.1.1.1 and 1.0.0.1 DNSs you can see it here https://1.1.1.1/
I have a top of the line,

I really wish to re-flash my firmware as a result of concerns about vpnfilter attack. I do not wish to be sending out beacon that I have been compromised. I am not sure that I have been, but as a precaution. This should be allowed. Please make it possible to reinstall current version of firmware, as it is my equipment and I should not have to depend on a third party to support/protect my equipment in such a manner. I fully understand that allowing consumers to upgrade to unstable firmware/ISPprovider combinations would be a bad place to be as a technology company; but please allow us to access as conscientious purchasers of your products to at least have the option of keeping our fine products un molested by male-ware. Leaving us without options will force us to look for companies that will.
I am regretting purchasing the combined box, modem with router, because of only a single firmware that is so controlled. Please find a way to give us some access. Sincerely, formerly ecstatic customer, that is a CTO and Network administrator.
theselfthinker Netgear's hands are tied in this matter the DOCSIS standard mandates that cable modem firmware is not to be allowed to be updated by end users/customers. In order to protect Cable companies and ISP's from issues and problems resulting in service theft, CableLabs and their DOCSIS specification require all firmware updates to go through ISP. You should be able to find more info on this on the CableLabs website https://www.cablelabs.com. If you are really worried about VPNfilter malware I would suggest contacting your service provider and ask them to push the current fw to your device again.
Have you even read this thread!? That is the problem most of us have. The service provider won't provide the update and claim they have never even heard of doing such a thing. Maybe you should send that link to all the service providers instead of your frustrated customers.
