  • Install OpenWRT 21.02 on Ubiquiti UniFi AC Lite

    Install OpenWRT 21.02 on Ubiquiti UniFi AC Lite

    In this video, we will install OpenWRT on the Ubiquiti UniFi AC Lite. This tutorial can be applied on other Unfi AC models, such as the UniFi AC Pro or the UniFi AC LR. After that, we will check out the WiFi throughput & CPU usage of the UniFi AC Lite running OpenWRT with speedtest, OpenSpeedTest & iperf3.

    For this installation, I will use the non-invasive method using mtd from UniFi (via ssh). If you are looking for tftp installation method with serial console, you can check out the installation tutorial for UniFi AP LR – https://youtu.be/9Z1F8CAweHs

  • Install OpenWRT on Mikrotik RB750Gr3

    Install OpenWRT on Mikrotik RB750Gr3

    In this video, we are going to install OpenWRT 21.02 on the Mikrotik RouterBoard 750Gr3 (Hex).

    Most of the routers from Mikrotik use netboot via tftp to install/recovery the firmware and we will do the same for OpenWRT. This video will also show you how to downgrade your RouterOS version to 6.49.2 and backup your RouterOS license key, before proceeding with the OpenWRT installation with TinyPXE. Besides that, we will do a quick speedtest to see the CPU usage. At the end, we will also enable hardware & software flow offloading to see if there is any improvement in the performance.

  • WiFi Fast Roaming on OpenWRT (Fast Transition)

    WiFi Fast Roaming on OpenWRT (Fast Transition)

    Fast roaming, also known as IEEE 802.11r or Fast BSS Transition (FT), allows a client device to roam quickly in environments implementing WPA2 Enterprise security, by ensuring that the client device does not need to re-authenticate to the RADIUS server every time it roams from one access point to another.

    We can easily configure Wifi fast roaming with LuCi. The required package is wpad (the full package, not wpad-mini nor wpad-basic).

    ESSID, encryption, key (password) and the Mobility Domain should be the same between each of the AP (node) while the operating frequency is advised to be different.
