I have MaxxWave hardware (X86)running what it says is “Version 5.5”. I’m looking
for the NTP package that will work with this platform. I’m a little confused as to
how my system is 5.5 when the latest release from MikroTik is 5.19. Will NTP
from 5.19, X86 work?
RouterOS versions are numbered sequentially, when a period is used to separate sequences, it does not represent a decimal point, and the sequences do not have positional significance. An identifier of 2.5, for instance, is not “two and a half” or “half way to version three”, it is the fifth second-level revision of the second first-level revision. Therefore v5.2 is older than v5.18, which is newer.
No, NTP package from a new version will not work. Simply upload the latest version packages (all of them) and upgrade the whole system: http://www.mikrotik.com/download
