This is really strange. How is this possible?
A few days ago I updated to Comcast Blast, and picked up a Motorola SB6120 Doc SIS 3.0 modem. The upload speeds are sometimes 2, or 2.2Mbps. No complaints, it's better than the 130Kb/s cap I had before. Anyway, I started testing CrashPlan backup site, which has no speed restrictions. When the blast kicks in, I'm getting upload speeds as high as 400+ Mbps. In this case, 411.6Mbps Wow. that's 51.4MB/s upload. Then after a few mins, my connection throttles back down to it's normal sustained rate of 2 or 2.1Mbps.
See attached Screenshot
What I don't understand is, My Netgear router is rated at 100Mbps, so how can I be getting these speeds? This is the router.
I've sent this screenshot to Crashplan support to see if there is something wrong with the readout of their software. There is no way these numbers are correct. I think even the most expensive Comcast business plan is only 10Mbps for Uploads.
