I have a rb2011u on 6.10 and didn'T find /system ups so I upgraded to 6.13 and the package ups is not there!
Anybody can direct me on how to install the ups package?
I verified that that ups package is there on 6.10. You will need the "all-packages" download not the upgrade npk. If you don't have it, you may want to upgrade your router so you can download it from the website. Alternatively, you may want to talk to you vendor and see if they can provide it for you.
