If you're getting error messages shown below when you log into your XR500 Nighthawk Pro Gaming Router:

Uncaught ReferenceError: Chart is not defined
Uncaught TypeError: c.draggable is not a function  
Uncaught ReferenceError: d3 is not defined
Uncaught TypeError: tree.invalidateData is not a function
Uncaught ReferenceError: topojson is not defined
Uncaught TypeError: Cannot read property 'addWidget' of undefined

Then it is highly likely you have the Bitdefender Anti-Virus/Firewall or another Anti-Virus/Firewall. This guide is specific to Bitdefender at the moment. You need to whitelist the router interface in order to prevent these errors from occurring. This will allow you to continue to use Bitdefender and access the router interface. Please follow the instructions below:

To add http://routerlogin.net and http://192.168.1.1 websites to the Bitdefender Whitelist:

  1. Click the B icon on the left sidebar of the Bitdefender interface.
  2. Click the VIEW FEATURES link.
  3. In the WEB PROTECTION pane, click Whitelist.
  4. Provide the address of the blocked website or online application in the corresponding field and click Add.
  5. Click Save to save the changes and close the window.
  6. Follow the same process for http://192.168.1.1

Only websites and applications that you fully trust should be added to this list. These will be excluded from scanning by the following engines: malware, phishing and fraud.

Once you have done the above you will need to reboot your PC, then access the interface and do a refresh without caching. For directions on bypassing cache, see Bypass your cache instructions.
