I today got stuck while trying to install/set up my USB-WLAN Adapter. It's a DWA-111 USB-Stick (Rev. A1) and my machine is currently running Ubuntu 12.04 LTS. (As far as I know it's got a RT73 chipset by ralink, but I am not completely sure.) So much for this.

The Adapter runs perfectly using a machine with Win7 installed but it does absolutely nothing when I plug it at my Ubuntu 12.04 machine. iwconfig and ifconfig show nothing, as well as the device is not listed when executing lsusb. So it seems it's entirely unknown to my computer.

Here's some output of lsusb, now showing the D-LINK device (as already described below in comments I just noticed the device is appearing and disappearing every now and then):

This error messages just keep repeating over and over.

Any ideas how do I get the device installed and running? And additionally any idea about the lsusb behaviour? Thank you!

lsusb has to list it anyway, try lsusb -v. Sometimes the vendor name differs from that is shown in windows. Check the IDs. – grimpitch May 5 '13 at 18:13
OK, just experienced a very weird behaviour of lsusb I just ran it several times and the 4th time I executed it, it showed the D-LINK device. But then, running lsusb a 5th time is disappeared again. (I'll add the output of lsusb above.) – ch.bailey May 5 '13 at 18:40
The disappearing device can be a power management thing, but still, it shouldn't disappear from the device list completely. Look for traces about that in the /var/log/syslog, /var/log/dmesg, and /var/log/pm-powersave.log. The kernel driver for this device is the rt73usb module, load it with sudo modprobe rt73usb. Also make sure that the linux-firmware package is installed. – grimpitch May 5 '13 at 19:49
Thank you @grimpitch . I found some information about the error in /var/log/syslog. I will soon add the output above as well. – ch.bailey May 5 '13 at 21:42
I suspect the device is failing. – chili555 May 5 '13 at 22:28

D-Link Systems DWA-111 802.11bg Wireless Adapter - [Ralink RT2571W]

Source: > Ralink RT2501USB/RT2571W (RT73) devices

Possible solutions:

(1.) How do I get a Ralink RT3060 wireless card working? (for 12.04)

Option 1. Try installing the latest compat-wireless backports package and see if it works ..

Option 2. Build and install Ralink's own drivers ..

(2.) Load the device-firmware drivers (to load firmware to device)

sudo apt-get install linux-firmware-nonfree

well, I tried all these steps but none works. Which also would lead to the conclusion that the device is broken - but as I tested it one more time on a Windows 7 machine and it worked I can say, that it's fully functional there. Just keeps disappearing again and again on my Ubuntu machine. – ch.bailey Jun 5 '13 at 18:48
Look at other RaLink issues on this forum. Click on that tag (below your question). – david6 Jun 6 '13 at 8:38
