I found the post linked below really helpful when figuring out how to download logs efficiently.
TLDR:
Download the program WinSCP
Connect your computer and your rover the same wifi network
Open WinSCP and enter the correct info (host name = the IP address of your rover, username = reach, password = emlidreach (or whatever you changed it to) and login
Now you can navigate through the file structure on the rover unit and download the log files you want.
