 How To Set Up Public Wi-Fi Hotspot/WISP with MikroTik Router and 3G/4G Modem


In these Tutorials, we will discuss:
1. Introduction to MikroTik Wi-Fi Hotspot
2. MikroTik Hotspot Gateway features
3. What is 3G Modem and its Usefulness?
4. What is User-Manager and its Usefulness in MikroTik Hotspot?



MikroTik Wi-Fi Hotspot can only be defined as HotSpot Gateway, which provides authentication for clients before accessing public networks. Hotspot can only work reliably when IPv4 is used. Hotspot relies on Firewall NAT rules, which are currently not supported by IPv6.

MikroTik HotSpot Gateway features:

MikroTik Hotspot has unique features, but I will mention a few here in this tutorial

  1. Different authentication methods for clients using local client databases on the router or remote RADIUS server;
  2. user account in a local database on the router or on a remote RADIUS server
  3. walled-garden system, access to some web pages without authorization
  4. login page, status page and log out page modification, where you can put information about the company
  5. automatic and transparent change of any IP address of the client to a valid address
  6. HotSpot can inform DHCP clients that they are behind a captive portal (RFC7710)
  7. SSL support for landing page/splash page 
  8. e.t.c

What is 3G/4G Modem?

A modulator-demodulator, or simply a modem, is a hardware device that converts data from a digital format, intended for communication directly between devices with specialized wiring, into one suitable for a transmission medium, such as telephone lines or radio. It's used for internet connection, and it can also be used as a multi-purpose device to send SMS/MMS and used to make phone calls on a computer.

What is a User-Manager?

User manager (UM) is a management system that can be used in various setups. UM can be used for HotSpot, PPP, DHCP, wireless and RouterOS users. User Manager is a RADIUS server application. The first UM test package was introduced in RouterOS version 4. The User Manager package is supported on all RouterOS architectures, including x86 and Cloud Hosted Routers.
