I have recently purchased a router with RB750G board which I would like to upgrade to the most recent firmware and OS.
It is currently running firmware version 2.39, with Router OS version is v5.14.
I have browsed to http://www.mikrotik.com/download. I am aware that there are three different software versions for download, i.e. 4.17, 5.23 and 6.0rc7 and I do not know which version is the one I should download and install.
Could you please advise.
Thanks
