WRN - Network reset script

  • Updated

Applies to Models:  WRN

Summary:

If you have network interface issues on the WRN and need to reset the interfaces, you can use the attached script to correct the problem.  This script removes the interfaces created by the WRN setup wizard and reconfigures the interfaces on reboot.

Step By Step Guide:

You will need a monitor, mouse, keyboard and the attached script.  The script can be downloaded directly to the unit or copied to a USB drive.  If you don't have internet access from the WRN, it is recommended to follow the USB instructions.  Below are the two options to put the script onto your WRN.  

To download the script to the WRN unit using Chrome, follow these instructions:

On the WRN, open Chrome and navigate to this article:

  • Scroll to the bottom of this article and click on WRN-Reset.zip to download it (Figure 1)
  • You will need to extract the script from the .zip file by clicking on the download button in Chrome and selecting Extract: (Figure 1)

  • Alternatively, you can extract the script by opening a terminal window and executing the commands below: (Figure 2)
    • cd Downloads
    • unzip WRN-Reset.zip

  • To execute the script, in the same terminal window type:
    • sudo -s <enter>
    • Enter the password for the wave user and press enter 
    • Then type:  bash WRN-Reset.sh  exactly as shown in (Figure 3)
Note:  You will not see characters being typed when you enter the password.

  • The network configuration will be reset and the unit will reboot.  (Figure 4)

  • After the reboot is completed, you can run the WRN Configuration Tool or use the Ubuntu configuration tool to configure the network interface IP addresses.  It is recommended to use the WRN Configuration Tool when available as opposed to the initial "WRN Setup Wizard" to prevent issues in the future.

To move the script to the WRN unit using a USB disk, follow these instructions:

Put the WRN-Reset.zip file onto the USB disk and insert the disk to the USB port of the WRN.
