Description: In this article, we will discuss a detailed stepwise method to block and/or unblock a wireless client on Ubiquiti Unifi Controller.

Introduction

If you are using Ubiquiti Unifi wireless network devices then it is quite possible that sometimes you will be in a situation when you would like to block a wireless connection connected to your network. Authentication methods are available for wireless clients for example authentication of clients through Radius or Voucher based login for a guest wireless client through Unifi guest portal. But still, sometimes the client is even not aware that his/her device is infected with malicious files or apps.
