New Netgear C7800 Low download speed on GB Internet

Hello,

I just installed a Netgear C7800 and the download spees are maxing around 400mbps on both wifi and wired connections. I looked on the firmware page on Netgear and it does not match. Does anyone know how to make them match or otherwise improve the speed. My old X1 hit 950 mbs over wifi, but had weak coverage across the house. Thanks!

 

Comcast firmware: V3.01.38

Actual Firmware: V3.01.43

Firmware is not typically related to speed capability. The Configuration/boot file is. What do you get for the upload speed ?

I just seen in another post, where the gentleman had Norton security installed and he was getting half speed, he did some testing and he ended up uninstalling it and now gets full speed again, just a thought

O/k so that shows that the correct speed configuration / bootfile is being pushed to the modem. Start here;
