Sorry for the necro, but this is one of the first threads that shows up when trying to do any research on firmware decryption for these models.
I have a small writeup on decrypting the firmwares here: https://github.com/ozwaldorf/FIOS-G1100/...5826807328
And the TL;DR "please give me the actual decryption part" is here: https://github.com/khang06/ubi_reader/co...b4fe461f76
Anyway, it looks like the SSID and password are baked into U-Boot environment variables and don't seem to actually be initialized in the firmware as far as I can tell, which is probably a bit disappointing for you guys, but hey, at least this router's firmware is decryptable now!
