AAA, NAC, Guest Access & BYOD

I have ran a few times into an issue with onboarding Android using the native Web browser. After downloading the network profile it prompts the below error message: 

Requested Range Not Satisfiable 
None of the range-specifier values in the Range request-header field overlap the current extent of the selected resource.

Requested Range Not Satisfiable
None of the range-specifier values in the Range request-header field overlap the current extent of the selected resource.

The above is HTTP Error 416.

Introduction

The Web server (running the Web site) thinks that the HTTP data stream sent by the client (e.g. your Web browser ) contains a 'Range' request which specifies a range of bytes which can not be satisfied - because the resource being accessed does not cover this byte range. For example if the resource - an image file for example - has 1000 bytes and the Range requested is 500-1500, then it can not be satisfied.

This error seldom occurs in most Web traffic, particularly when the client system is a Web browser. The URLs in this case are typically standard hyperlinks found on Web pages, which very seldom use the 'Range' specification.

If you run into this issue, just clear the browser cache or use a different browser and it will start working again.
