Description
After installing the free trial version of RouterOS on a PC, you will certainly want to keep using it.
To do this, you need to purchase a license key.
There are four types of RouterOS license keys available, indicated by a “level number”. The lowest level is 3, which has wireless client functionality and limited number of active users, and the highest is level 6 which doesn’t have any limitations.
all RouterOS installations allow you to use unlimited number of interfaces, include limited technical support over email and
never stop working. In fact, the RouterOS license allows you to install any upgrades that MikroTik might release, up until the last upgrade of the next major release since you purchased your key. If you want, you can keep using RouterOS on that final
release – RouterOS license never expire
