Enjoying the full internet speed for your subscription depends on using equipment that is compatible with your internet service.

Reference these tables to ensure your device is compatible with your Comcast Business speed tier:

Every device listed below is DOCSIS 3.0 and IPv6 compatible.
Note: For retail purchases, only devices with a check mark in the corresponding Retail column are currently approved for use.
As new technology emerges, older devices become obsolete and will not work with new features or deliver subscribed Internet speeds. These older devices are deemed to be at the end of their useful life which means we no longer install the device and recommend that customers do not purchase these devices, whether new or used.
Reference this table to see if your modem is an end-of-life device and not recommended for use.
End-of-life devices are eligible for a free equipment upgrade. Please contact Business Customer Support at 1-800-391-3000 to schedule a technician to replace your equipment.
