not getting expected download speeds

I recently upgraded from 100Mbs to 200Mbs speed, but I'm only getting 90Mbs max and frequently less than that.  I'm using a netgear CM600 modem and netgear R6900P router.  I'm using a wired connection to the router for my performance testing.  I don't see any recent errors in the modem error log.  Below are the modem stats.

Looks like I don't have permissions to upload an image with the stats.

Since you are a new poster, it needs to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting it at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to it here.

Re: not getting expected download speeds

The stats are o/k. What do you get with a computer connected directly to the cable modem (no router in the mix) ? And is that computer capable of doing over 100 Mbps speeds (has a 10/100/1000 Gigabit network adapter) ? And what are you getting on the upload speed ?

Re: not getting expected download speeds

I tried connecting the computer directly to the modem and got the same result.  70Mbs download 17.6Mbs upload.  12ms ping.  I checked the status of the ethernet connection and it shows speed: 1.0Gbps.
