I keep having to reconfigure time machine because the hostname of the router is changing. For instance I modified my router to say "AC86U-DEN" in the hostname tab of LAN - LAN IP, & when I go to time machine i'm seeing "AC86U-DEN-27.local". If I reboot the router it changes to something else. I am running the latest Merlin 386.4. I honestly never ran into this problem before IDK?
