MikroTik

When I upgrade via ftp I usually upload the system package, reboot and then upload all of the utility packages.

I think with this method I lose the settings, like the wireless configuration etc, right?

Can I just upload the system and all of the utility packages at once and expect it to upgrade everything on reboot and keep the settings?

Thanks for your help!

We did it several times, and it works.

just upgraded three of our MT's this way (upload everything and reboot) no problems no configuration losses. Should work fine.

Suggest ftp **all** the packages you want, then reboot.
Remember to include only ONE of the wireless packages (standard or legacy).
Worked fine for 6 different upgrades of RouterOS with wireless

I think upgrading just "system" then the others later is creating the problems you describe, the packages will be out of step with the system portion.
