Change Default Access Code NVG589

The default access code on our NVG589 has been compromised.  Is there a way to change it or block access using this password that's on the box itself?

Are you asking about the Device Access Code or the Default Wifi Key? Both can be changed. If you need to change the wifi key do this:

 

Enter the Default Gateway (192.168.1.254) into your Browser, go into something along the lines of "Home Network" then "Wireless". Enter the Device Access Code when prompted. Change "Security" drop down from the "WPA-Default" to "WPA-PSK". Once this is done, you'll be able to erase the existing key from its text field and type in your own. Save. If you're doing this via wifi, you will lose your connection. You may need to "Forget" the network the reconnect with the new password.

 

If you need to change the Device Access Code:

Log into the Default Gateway (192.168.1.254). On the "Device" tab, click "Access Code". Enter the old one and make a new one.

I'm taking about the Default Access Code and I know it can be changed, however anyone that knows that code can log into the router even after it's been changed.  This is what I want to avoid.

Only someone who is already connected to your network can access the RG and they can only be connected to your network if you gave them either the wireless password or are connected directly to the RG. Once connected, they can see the RG but cannot make any changes without the device access code.

Once it has been changed, one cannot log in to the router with the original (on the side of the RG) code without resetting the RG back to factory settings.

I understand that.  They got the device access code from the sticker on the box itself and now I need to restrict access to the box and I can't get an answer on whether the DAC can be restricted or changed permanently, eliminating access to the old DAC.

Permanently, no.  A return to factory settings takes it back to, well, factory settings.  So it would always return to the original if the device were reset to factory settings.  But if you prevent it getting reset to factory settings, the original access does not matter.

I don't think it's the case that you need to reset the box to factory settings.  After changing the access code, basically the password to the programming interface of the box, you can still input the old one and get in.  I'll need to test this but from what I recall that was the case.

The problem is that device access key. If they remember it or have it written down then you're pretty much screwed. BUT if you can keep them off any devices with internet they wont be able to change it back. FYI you can change this without ethernet connected devices such as phones.
