Paying for Gigabit, getting 90mbs

My internet is always capped at 90mbs.  I'm paying for gig speeds & unlimited data.  Why is this happening?  I even upgraded my modem to the Netgear Nighthawk CM2000.

Speeds limited to just under 100 Mbps when you subscribe to a higher speed tier are most often due to either:

  • network adapter set to or only capable of "Fast Ethernet" speeds
  • a defective Ethernet cable

If you can't find the problem or you'd rather have Comcast take care of it, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. If they can't fix the problem remotely, insist they send a tech out to identify the cause and correct it.

If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit unless you have their Service Protection Plan (https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.

Just want to add that make sure you are using a minimum of a cat5e ethernet cable. Cat6 would be even better.
