How To Reset a Lost or Forgotten Password

How To Reset a Lost or Forgotten Password

Local and/or remote access to Wheatstone audio processors can be password proetected. If the password is lost or forgotten access to the unit will be blocked until such time as the password
is found or the unit is manually unlocked using the following procedure.

Preparation

Before getting started, we will need the following:
  1. A Windows PC with an Ethernet port.
  2. A Telnet client and Windows command prompt. (PuTTY works well in Windows 10 and 11.)
  3. The Windows PC configured to use a static IP address in the same network address range as the processor.
  4. The processor’s network IP address.
  5. A straight through or crossover Ethernet cable.
Once the PC and processor are connected together with the Ethernet cable and both are powered up we’ll test connectivity between the two by using the common "ping" command.
ping command:
  1. Open a command prompt on the PC.
  2. Type the following where xxx.xxx.xxx.xxx is the processor
  1. ping xxx.xxx.xxx.xxx
The processor should reply to the ping command. Below we are pinging a local device on the IP address 192.168.1.160 to demonstrate what a successful ping looks like
C:\Users\Lab>ping 192.168.1.160
  1. Pinging 192.168.1.160 with 32 bytes of data:
  2. Reply from 192.168.1.160: bytes=32 time<1ms TTL=64
  3. Reply from 192.168.1.160: bytes=32 time<1ms TTL=64
  4. Reply from 192.168.1.160: bytes=32 time<1ms TTL=64
  5. Reply from 192.168.1.160: bytes=32 time<1ms TTL=64
  6. Ping statistics for 192.168.1.160:
  7. Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
  8. Approximate round trip times in milliseconds
  9. Minimum = 0ms, Maximum = 0ms, Average = 0ms
If the ping command was not successful the ping replies would appear as follows:
  1. C:\Users\Lab>ping 192.168.1.160
  2. Pinging 192.168.1.160 with 32 bytes of data:
  3. Reply from 192.168.1.15: Destination host unreachable.
  4. Reply from 192.168.1.15: Destination host unreachable.
  5. Reply from 192.168.1.15: Destination host unreachable.
  6. Reply from 192.168.1.15: Destination host unreachable.
  7. Ping statistics for 192.168.1.160:
  8. Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
  9. C:\Users\Lab>
Note: In the above example the 192.168.1.15 address is the PC originating the ping.

If the ping test to the audio processor is successful we may proceed to the password reset task.
If the ping test was not successful, the cause must be resolved before the password reset task can be performed. Please see Appendix A for troubleshooting suggestions.

Changing the IP

Using your Telnet client, connect to the Wheatstone audio processor on its current IP address. The port number is 23.

A prompt will appear asking for login credentials – use the following user name and password:

user: knockknock
password: whosthere (note there is no E in whose nor an apostrophe)

Once logged in, type the word help and hit enter.
A list of available commands will be shown; one of those commands will be clear_pw or some variant (different processor models may use a slightly different command).
Type that command and hit enter.
The unit should respond with a message that the password is cleared and that a reboot is required.
Power cycle the unit, after which security will be off (no password will be required.)

Appendix A - Troubleshooting Connection Issues

If you can't ping the processor, try these steps:
  1. Disable wireless. If you're on a laptop and the ping test fails, Windows could be assuming that the wireless card is the primary network interface. Disabling wireless will force the laptop to use the wired Ethernet card, which is what you will need to use to reset the password.
  2. Verify the PC's network configuration. Windows uses dynamic IP addressing by default (also known as DHCP). Are you sure your network card is set to a static IP in the same range as the audio processor? Are you sure you're not on the same IP as the processor? (A quick test: type in ipconfig at a command prompt. If the network connection returns a link local address instead of the static IP address that you set, Windows found another device on the network with the same IP address and changed your network interface to a link local address to avoid a conflict.)
  3. Use an Ethernet switch between the PC and audio processor. The network connection on the back of the audio processor is 10/100, and some older laptop network cards won't negotiate down from Gigabit to 10/100. If that's the case for you, putting a switch in the middle will do the speed conversion.
