The broadband light on the Arris NVG510 is blinking red on an

WiFi working and connected to the expected SSID. Why doesn't the
broadband issue affect the wireless connections?


You seem to be certain that the red light means that communication are
absolutely and totally lost but what happens is it merely means that
the connection is intermittent or sub-optimal? What if the "red light
flashy circuit" is reacting badly?

Manuals don't always say what they mean -- sometimes the manual writer
really has no clue of what is actually going on beyond some vague
notions and notes from the designers (and designers don't always pay
much attention to correcting the drafts of the manuals even if they
are actually included in the loop). If you are sure that you have
connection and can perform tests to prove it then you _have_
connection no matter what the light is telling you. Think of it as a
defective "check engine" light -- put some black tape over it. When
the communications are truly lost then you will have _no_ question
about it and you can gaze at the LED then.

That said, I'd certainly be badgering my ISP for an immediate (free)
replacement of the old one and the flashing LED is as good an excuse
as any.

Agreed, it looks like the h/w is failing.

The reviews for the product are Not Good.

It could easily be the Firmware Elves at fault.
