Netgear R6300 V2 firmware update?

Hi Kptaylor,

You should be able to update your firmware on your own if your Netgear is a stand alone router and your Netgear R6300V2 is showing that it's a stand alone router.  We don't provide firmware updates to stand alone routers. Do you have a Netgear modem or a Netgear WiFi modem? If so, we can check if your modem has the latest firmware.  Please send us an email to cox.help@cox.com with the full name and address.  Please include a link to this post so that we have a history of what's going on. Thanks.

Well, the router (not modem) is stand alone, but the firmware is locked to Cox updates since it's a Cox-supplied router for my Gigablast service. I cannot update it on my own. When I either click the "Check for new firmware" button or try to use the update I downloaded to my computer from the Netgear website it won't allow me to process the update. It's looking for a Cox-approved update. 

That is not true for me Chris.  I've had Gigablast for about a year and a half with the R6300 V2.  I check about once a month on the Administration tab of the router interface and it shows "checking for updates" and every few months it downloads one from Netgear and asks if I want to install it.  I have manually updated about 5 times this way.
