RT-AC66U Reset/Clear NVRAM

[bbunge]

Can I get an idiot-proof answer for myself?

Reset with WPS held clears NVRAM: Yes/No

and/or

192.168.1.1 > Administration > Restore/Save/Upload Setting > Factory default (Restore button) clears NVRAM: Yes/No

I can't figure out how to log into SSH. It keeps tellin me to put in the password, which I do, and it won't let me in and then eventually locks me out for several minutes.

Yes to both... sort of. And the best recommendation is to do a hard factory reset which is different based on router model/
