I have bought a RB450G (I’ll get it in 2 days I hope) and trying to download RouterOS 4.17 but ir doesn’t work in any on the links posted at download section: http://www.mikrotik.com/download.html
*) fixed occasional print command stalling when lots of items;
*) fixed RB1100 ether11,12,13 and RB800 ether3 resetting problem;
*) implemented usb power-reset command on RB SXT 5HnD;
*) wireless-nv2 package now includes the same fixes as RouterOS v5rc11;
