First and formost.. I have Gigablast. I only have a Router with a ONT and not a modem.
Your own forums cause conflicting information concerning firmware updates. one post says you don't do firmware others say you test and will push updates. I have yet to see a single firmware update since i have had the modem. this is going on over 2 years now. what is the deal?
Routers have never been updated by Cox, only modems, and you said you have a ONT instead of a modem. If you want to upgrade your router's firmware, then it is up to you. See here.
::edit:: I should have said never been AUTOMATICALLY updated through the CMTS, because there is no CMTS when you have fiber. I forgot about remote support.
So even thought the router was provided by Cox, with a special version of the firmware on it.V220.127.116.11_10.0.85COX i'm able to upgrade my firmware anyways and not lose any of my speeds?
No i'm not experiencing issues of that nature. I'm more concerned with KRACK and other features of the Router which aren't working properly. DDNS throws a error so fast on the screen I can't capture it.
Becky, I have heard that this was being worked on in the past.. Dec 2016 to be exact.
Sorry I took the thread a bit off track.
Back on track, how about disabling the wifi on the R6300 all together and then buy your own wireless access point(AP). Not only would you be able to negate the R6300's wireless vulnerabilities, but it would also assure your wired speeds go untouched. I recently made that switch myself with a Unifi AP, so if interested, I can give lots of advice.
