WR31 Password Recovery


I have a WR31 I’m trying to configure to be utilized and have defaulted it but the password combinations from the manual do not seem to be working. I know that they sometimes can be delivered with a unique password but it’s been lost. Is there anyway to recover it? Does defaulting it completely restore it to that unique password possibly or another combination?

Any help would be greatly appreciated,

Thank you,


If the device has a unique password, you should see it on the label of the device.
Factory resetting it should bring back the password in most situations. Firmware downgrades might change it, for instance.

Here is a link to a KBase article talking about the Digi Device Unique Passwords: Digi Device Unique Default Passwords | Digi International

Note that the WR31 is a SAROS device, so in regards to the exceptions, please look at that.

Also, something else to try, connect to the device via the serial. You may need to use a USB to serial converter if your PC or laptop does not have a serial port.
Look in Device Manager to know what your serial port is on your laptop.

  1. Use PuTTY, or similar, to connect to your WR31. It should be set with 115200, 8, 1, N, No Parity, No flow control. Note that your WR31 will not require the password via serial.
  2. Enter the following commands:
    user 1 name xxxxxx
    user 1 password yyyyyy
    config 0 save
    (where xxxxxx is the name you are assigning and yyyyyy is the password)
    Try logging in with your new credentials.
