// ADDING THE NEXT ROW THE ADMIN INTERFACE WORKS ON CHROME
// Replace the readfile.js with this readfile.js. It can be done
// using the chrome extension Requestly. Add a redirect request rule
// where source equals http://<ROUTER_IP>/readfile.js to the url of this file
// generated using rawgit:
// 1. click on Raw button of this gist and copy the url
// 2. go to rawgit.com and past the url
// 3. copy the rawgit production url and use it in Requestly
// for example i get this: 
// https://cdn.rawgit.com/nikiink/0966d5bc50a1fec7e2b7062f1d0bbc6f/raw/369cb26eec26d5c2a98474814a6449359dd738b7/readfile.js

The admin interface of Sitecom WL-153 v1 002 opened with chrome generate the error netscape is not defined and the page is not displayed correctly. Defining on the top of the file readfile.js the global variable window.netscape to false resolves the issue.
