Confirm your modem is up-to-date

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.

Starter Speed Tier
Vendor Model Product Name
SMC Networks SMC8013WG-ADC SMC EZ Connect Wireless Cable Modem Gateway
SMC Networks SMC8013WG-ADR SMC EZ Connect Wireless Cable Modem Gateway
SMC Networks SMC8013WG-CCR SMC EZ Connect Wireless Cable Modem Gateway
SMC Networks SMC8014WG-CCR SMC EZ Connect Cable Modem Gateway

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.
