I installed a new router (airport 4th gen to new netgear 6300) and all went well. I also installed a new seagate central NAS. My challenge - copying data from old USB drive which used to be connected to airport extreme.. It is looking for credentials and I'm not sure what those would be? Any ideas? I'm currently thinking I'll need to reinstall old router temporarily and move things around that way.. thanks in advance for any better ideas.
