I try to upgrade my Mikrotik Router 450G to the current version. I upload the .npk file and restart the router. On restart it does not boot properly, I couldnot find the device ip in winbox search neighbour and it continuously give a starting beep sound every 20 seconds. What might be the solution for this problem, please help me.
If I install using netinstall, does the old liscence will be valid? Shall I have to buy new license?
