Xfinity AX6000 Gigabyte internet

I recently bought the AX6000 hooked it up update to latest firmware and ran a speed test. Was only getting 340-400 mbps out of the 1200 mbps. Also did the speed test on the Netgear app and only getting 450 mbps. Any suggestions?

Re: Xfinity AX6000 Gigabyte internet

Is this wired speed tests with a wired PC? 

You should see 1.2Gb with a wired PC on the MultiGig port in back with a multigig ethernet adatper supported PC.

 

What Firmware version is currently loaded?
Please post a copy and paste of the modems connection status and event log page.

Re: Xfinity AX6000 Gigabyte internet

Power levels and correctables and un-correctables are good.

 

However there are some criticals and warnings in the event logs that the ISP needs to resolve. 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.

 

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

Re: Xfinity AX6000 Gigabyte internet

Criticals may have cleared and those were at initial connection with the ISP services. However Warnings are still being seen currently.
