For an Xfinity gateway, look for a standard range extender that supports the router WiFi and security settings. TP-Link RE715X and NETGEAR Nighthawk EAX15 are starting points; confirm model-specific mesh support separately.
Quick answer
TP-Link RE715X is the lead choice for a Gigabit Ethernet port and WiFi 6, while NETGEAR Nighthawk EAX15 is a WiFi 6 mesh extender option. TP-Link RE550 is a dual-band alternative with a Gigabit port. Confirm the extender works with your particular gateway; mesh roaming features are not guaranteed across brands.
