CM3000 on Xfinity with 1200Mbit, onlt getting around 940Mbit with link aggregation
I just purchased a CM3000 for use with my Xfinity 1200mbit plan. It's currently running firmware 6.01.04. It was set up in link aggregation mode and connected to my router via ethernet ports 1 and 2....
The Ookla speedtest, both app and in-browser is multi-connection, so shouldn't this be multiple data flows? I've seen other's Ookla results with link aggregation and it's well over 1000Mbit, so is there something wrong or is the Ookla speedtest not truly multi-connection?
As a test, Do you get 1200Mbps directly connected behind the CM modem with out the router being connected and LAG disabled on the CM modem?
If you have a 2.5Gb or higher capable ethernet PC or Ethernet adapters, you should see what your pay for from your ISP from the CM modem with out the switches in line.
This would be first thing to check and test.
