"AC1900" is a speed, not a model number. Look for "Model" on the
product label. Current firmware version?
> What does it mean when your firmware is out of date on your device?
Normally, it means that newer firmware is available for it. Who said
what, exactly?
Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation. Get the User Manual (at least). Read.
Look for "firmware"?
