"No Wireless Interface Present"


I’m trying to setup wireless for my Pi B+ using a D-Link DWA-124 dongle. When I plug it in I get a blue flashing light and when I go to the Network settings it says

Status: No Wireless Interface Present
IP address:
Signal Strenght: 0%
BitRate: Mb/s

What am I doing wrong? Also, how do I get version 1.51? It appears I am still on Version 1.5 and when I click the Check For Updates button I get a message saying

Retrieving Updates, if available

but then nothing else ever seems to happen…These are rather embarrassing questions.

V1.51 can be downloaded here

sourceforge.net/projects/volumio … p_redirect

The problem remains though.

you can manually edit the interface file: /etc/network/interfaces
