After I rebooted, all I get is "This site can’t be reached The connection was reset.".
The reset of the Internet works great, it's just the admin interface that is gone.
Looks like I need to do a master reset of the Smart/RG. Is there anything else I can try first, and do I need to worry about any SONIC specific settings. I did save my router settings to a file, and I can probably even find it.
Thanks for any help.
