Nighthawk Rax30 not showing correct speed after fiber installed
Old comcast name/login on Nighthawk rax30 does not allow full speed of new ATT fiber speed of 500. Instead, speed test shows 87. ATT technician connected my NH to the ATT Gateway with an ethernet cab...
Hello,
wo Networks Are Active:
Your old Comcast network name is still being broadcast by the Nighthawk RAX30.
The ATT Gateway is broadcasting its own WiFi network under a different name.
Speed Difference:
The ATT Gateway’s WiFi shows ~480 Mbps (expected on fiber 500).
The Nighthawk’s WiFi (old Comcast SSID) shows only ~87 Mbps.
Your NH RAX30 may not be correctly set up in bridge/AP mode, or it's:
Double NATing, or
Not getting full bandwidth due to a LAN-to-WAN bottleneck, or
Ethernet cable is plugged into the wrong port (e.g., LAN port instead of WAN/Internet).
