How to reset NanoStation M5

In my last post about NanoStation 2, I added 2 ways to reset M2 to default settings. This procedure is similar to M5 Station. But what to do if you can’t reset both methods? This answer will be on a 3rd way.

First way:

  • Connect your device to pc or notebook and enter this  IP address: or the other one you set.
  • Enter login and pass (by default ubnt)
  • Choose “SYSTEM” at the menu
  • Press “Reset to Default“.
  • Then just wait.

Second way:

We recommend doing it when you forgot your password or can’t connect to Nanostation via WEB.

  • Connect it to pc or notebook and turn on.
  • Press and Hold “Reset” near the main LAN port and wait 8-15 seconds.
  • On some device the reset button on POE
  • When done you will see all indication lamps will blink a few times.

If after resetting you can’t connect to Nanostation m5 you need to do this:

  1. check cable connector (anyway)
  2. Set the LAN IP (ipv4) to subnet mask
    default gateway  (where to do it? > connection setting > TCP/IPv4 )

Third Way:

There are cases when Ubiquiti hardware needs to be restored after unsuccessful flashing, or the device is constantly rebooted after an incorrect WatchDog setup.

Some installers may disable the Reset button in Ubiquiti’s settings so that you cannot reset the device to factory settings and enter its settings. This article will help you in such situations.

Usually, in Linux operating systems, the TFTP program is already present. If there is no TFTP then you have to install it. In Ubuntu, this is done with the command Sudo apt-get install TFTP.

To firmware the Ubiquiti device run the following commands in the terminal:

root@ubuntu: tftp
tftp> bin
