Thanks guys,
My ISP is Hood Canal Communications on the Olympic peninsula. we were an unserved area until last year so a nice fiber optic was installed last year, very nice. my modem is an Adtran SN ADTN225050CD
not sure what you mean by downgrade the system? Understand the factory reset maybe. I do not follow to upgrade to v.21 FW. my current FW is v7.2.7.15 and shows it as being current where would I download the older FW from.

IPv6 is broke on v.15 FW, last known working FW was v.21. IF you want to try v.21 then you'll need to downgrade FW to v.21 and then factory reset and setup from scratch. Be sure to disable the auto update on v.21 so the system doesn't re-load v.15. Or just keep IPv6 disbled for now until NG and ISPs get this all figured out for IPv6. All up to you.
