said by madbear:So all seems well... for the time being. Does anyone know how often those certificates are updated? I really like having a spare modem around in case of emergency, but am I going to have to pull it out of storage every few months and connect it to keep its firmware/certificates current?
Here are the expiration dates for the certificates I extracted from the NVG510. I assume r27 contains the same ones:
SBC Services , Inc Root CA - August 22, 2012
SBC Services, Inc. Enhanced Services CA - August 22, 2012
ATT Services Inc Root CA - February 24, 2031
ATT Services Inc Enhanced Services CA - February 24, 2021
Motorola 802.1x Root CA - June 19, 2019
Motorola 802.1x AAA server CA - June 19, 2019
So it looks like you're safe until June 19, 2019, unless AT&T decides to change something else. If the Motorola CA isn't used, then you have even longer (2021)!
