    Performance is excellent. I did have difficulty with setup and had to phone the cable company twice to complete. I expected auto connect and that did not happen. But once set up it works great.

    I upgraded from a CM1000, and I'm using Gigabit service from Spectrum. Utilizing the 2.5GB port on the CM3000 I'm getting all of the 1GB the over-provisioning data I was losing with the previous modem. When Spectrum adds 2GB service in the future I'll be ready. Easy install.
