If you already tried resetting your Ubiquiti ISP Wireless device (ex. airMAX, airFiber, LTU) to factory default values with the reset button and you can't access the unit, we recommend that you perform a TFTP recovery. Then I did some speed tests. Sitting about 10 meters away from both Ubiquiti Unifi UAC-Pro (one of the enterprise access points) and AirCube, I got the following results.

Aircube can be configured as either AP or repeater. Every major configuration change results in having to restart the device. For this customer, AP is what I need as it will be connected to a wireless P2P link. Repeater is useful for situations where you want to connect to a router further away and place your own access point in the middle. Optional) If you would like to restrict access to the port forward, you can also add a Source IP/CIDR subnet mask. For example, adding 192.0.2.1/32 to Source IP/Mask would allow only 192.0.2.1/32 to access the Port Forward. For airCubes (ISP and AC): Push reset button and hold while powering unit.LED panel should blink fast several times, continue holding the reset button and the LED should turn off. Now you can release the reset button and the LED will flash slowly three times. Generic Linux distributions have an integrated command line TFTP client. From a PC running Linux, you can upload via TFTP by typing into Terminal the following commands: root@ubuntu: tftp 192.168.1.20

This article describes how to enable & configure port forwarding on ISP Wireless devices, as well as steps to test & troubleshoot that port forwarding was successfully set up. The instructions in this guide assume that your device is already configured with an active Internet connection.

The version. Initially you must use the same airOS firmware the device was running. Once the device is recovered, perform a regular upgrade via the WebUI to the latest airOS firmware. If no DHCP server is present or an IP cannot be obtained via DHCP, the radio will revert to 192.168.1.20By reloading fresh firmware to restore the device, this process can also be useful to recover devices that have appeared to fail when no other solution is working. The UISP range meanwhile enables service providers to build and manage wireless networks for their customers. UISP products include the popular airMAX, airFiber, LTU, and Ufiber devices, delivering high-speed wireless and fibre connectivity for point-to-point and point-to-multipoint applications. The supplied power adapter is 24V and it can power another Ubiquiti 24V device through the PoE out port without having to connect a PoE adapter into PoE In port. Doesn’t seem like a big deal but PoE adapters cost money so this feature will save a little bit. Go into the same directory structure as the firmware (e.g., assuming that you have stored the image files in c:\firmwaredirectory, type the command: cd c:\firmware) and enter the following (for help type TFTP -h) , e.g.:
