RouterOS has a multi-level license system, when you installed it 1st time you will get a demo license that will expire within 24 hours of its installation time, the important thing you need to know, the configuration you have done in the OS will be erased on the time of expiration of the license.

License Leveling:

There is a total of 6 Levels of License in RouterOS or in Mikrotik Switch and Router. Although those licenses are freemium.

  1. Level 0: A Demo license used for only test purposes will expire in 24 hours. You can use all Mikrotik Features only for 24 Hours Trial.
  2. Level 1: A Single User License, free for a single user. The features that you can’t use are wireless AP, Wireless Client, Bridge, RIP, OSPF, and BGP protocols. You can claim this license by just opening an account at > Account > Key/License > Get the Software Key from RouterOS > Submit it to Mikrotik. You will get a free Level 1 key.
  3. Level 3: This License is required by WISP(Wireless Internet Service Provider) and CPE(Customer Premise Equipment). This License doesn’t have support for Wireless AP, which means you can’t have a wireless access point creation option from the router. You need to use the external router from any company which has access point support on it. It can be any company. This license is not sellable and comes with a small-end router of Mikrotik.
  4. Level 4: This License is commonly used on budget friend routers/switches for homes or small offices. You will get all RouterOS features. In the feature, you have some limitations like you can only able to use 200 PPPoE tunnels, PPTP tunnels, L2TP tunnels, OVPN tunnels, and HotSpot active users and 20 Active User Sessions. However, it’s a good level license for small user. This will cost you around $45.

However, all licenses are created based on the user's needs. You can upgrade, downgrade, or transfer your license from one to another router or switch or PC Mikrotik. Transfer license will cost $10 every time. License costs are one-time.

Which Router I should pick?

Wow, it’s a high-level question when it comes to with/without any requirements. Don’t worry.

Let’s Say, You have a small office, where you have 15 Employees and some guest users. Of them, 10 of them have Desktop PCs and 5 of them have Laptop. Guests are limited to use with wifi but you have a low budget for that.

As per this requirement, Mikrotik has a router in the HAP Series.

HAP RB951Ui-2nD. Created for Home and Small offices. has support for wireless and switching.

It has 2.4GHz Wireless, Wireless AP, 650 MHz CPU,64MB RAM, and 5–10/100 Ethernet ports. Best for Office Router. You will need to buy a switch from Mikrotik or any company you want. Connect your router to the switch by LAN cable and connect your 10 pcs to the switch. Config your Mikrotik and done. It will start providing internet. In Wireless AP in Mikrotik Settings, you can make multiple SSIDs as per your requirement.

  1. 10 Pcs connected with switch. Switch Connected to Mikrotik.
  2. 5 Laptops are using wifi from Mikrotik.
