Same problem here. I online-chatted with a techy and they said that I am provisioned for 150Mbps. They sent the "codes" again to make sure my modem was configured correctly, but no dice, unfortunately, still "only" 100Mbps speeds.
A while back, when Cox upgraded us 50Mbps users to higher speeds, I went through a bunch of calls with the techies and ultimately just gave up. About a week later, I was magically up to the higher speeds, so I have to assume it was something on their end.
Also, I had Cox hardware techies out at my place last year and they replaced all my cables, so for this "free upgrade", that shouldn't be the problem.
I know this post isn't helpful to anyone in the same predicament, but hey, I'll wait a few weeks and see if anything changes like last time :)

I suspect your computer has a 100 Mbps NIC. Is 100 Mpbs your actual speed or is that an approximation, i.e. actual speed is high 90s maybe? If you do have a 100 Mbps NIC, your download speed can never reach or exceed 100 Mbps unless you upgrade your NIC, even if Cox is pushing speeds in excess of 100 Mbps to your modem. The speed to your computer should max out somewhere just below 100 Mbps due to network overhead.
