NVG510 Diagnostic Test Fail IP


NVG510 Diagnostic Test Fail IP

Why does the IP test fail on diagnostic full test and all others pass?

Is this a CO card issue in the CO that needs changed?

In a "check for open port check" it says modem can't be pinged. Is this due to the IP fail test meaning the modems IP can't be seen from the WAN inbound?

This IP fail test happens on 2 of the NVG510 Uverse modem/router combo.


Basically asking why this test fails, and what to do to make it pass.

Re: NVG510 Diagnostic Test Fail IP

I am having the same issue. I am setting up a Wordpress server on my NVG510 and I can not get the outside world to connext to the server if the default gateway is not working?!!?!?!? Am I wrong in this. What do I have to do to make this work. I have tried to reset the router and no go. I have to assume it is an error on ATT's end?


Need help!


Here is a screenshot from the IP Diagnostics test.

This does look like an issue between your modem and the AT&T IP network.
