Browser speed test is faster than internal CAX30.
Hi,
I just connected the CAX30 and the browser speed test shows a D/L of 933Mbps. The internal D/L speed test is around 340Mbps. The upload speeds match. Everything is fine on spectrums end. Netgear just stated that power levels are an issue but spectrum says that they are fine on their end.
The latest FW was installed prior to setup.
Cable connection status shows as POOR.
After running the diagnostic:
| Cable Diagnostic | |||
| Status: Poor | |||
| Action: [Downstream Power Level] Try these actions (Click the Refresh button after each step): 1) Make sure the coaxial cable is tightly connected. 2) Remove any unnecessary splitters. 3) Replace any required splitters. 4) Contact your service provider for troubleshooting help. | |||

Thanks
Power levels are a bit too high:

The Warning seems to indicate something with the power that the ISP should take a look at. Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.
Also the internal speed test maybe picking a speed test server that is busier or not as accurate as other speed test services located near you. Ya I wish we could pick the servers with in the modem.
As long as your getting to spec speeds from a wired PC thru the modem, you'll be fine.
