Spider! LinkSys WUSB600N Wireless


Abstract I describe how I setup my LinkSys WUSB600N Wireless USB stick to work on my GNU / Linux environment and, enabling the speed of wireless "N" (802.11n). Environment
The solution was tested with distributions Kubuntu 9.10, 10.04 and 10.10 64bit.

The PC is a Dell Inspiron 6400. kernel versions tested: the 2.6.31-15-generic

the (current)
2.6.35-22-generic

.

Hardware seems that the key used by the wireless chipset is Ralink rt2870.

kernel module The kernel seems to recognize the hardware, but load the incorrect driver for this usb wireless rt2800usb


# lsusb
...
Bus 001 Device 002: ID 1737:0071 Linksys WUSB600N Dual-Band Wireless-N USB Network Adapter
... Other useful commands for analysis

# # lshw-C network lsmod flies to the form from memory:

# rmmod-r rt2800usb
or to make the system reboots.
In a terminal window (eg Konsole
) with administrator rights, enter the following command:

# tail-f / var / log / messages
In this way you can check the flight

system messages.

Now enter the wireless key, wait a while and then see if the rt2870 module is in the list of kernel modules loaded in memory:

# lsmod
rt2870sta ... 552,712 ... a

But now the work is not yet finished, the stick still does not work and there are errors in the system messages relating to the improper loading of the module rt2870:
# less / var / log / messages
Note: Press "/" to start a search and type "rt2870" (all this without the quotes) to start a search of the text "rt2870".

Press "n" to advance research to the next item found, "N" to search for the previous element (or "p") and "q" to exit less .

The system warns me that did not find the configuration of the wireless key in the file:

/ etc/Wireless/RT2870STA/RT2870STA.dat

and in fact no such file exists in my system.

Search and Internet research, I finally found some references:
https: / / bugs.launchpad.net / ubuntu / + source / linux / + bug/377745

The driver and documentation can be downloaded from the site of Ralink

at:

http://www.ralinktech.com/support.php?s=2

for my WUSB600N key (which requires the kernel module rt2870sta) I downloaded the link: "RT2870USB ( RT2870/RT2770) "

In the downloaded package that I did was grab the file" RT2870STA.dat "which must then be edited and copied to / etc/Wireless/RT2870STA. The explanation of the parameters found in the corresponding text file README_STA.
... and finally now my wireless works fine with 802.11n.

Others prefer (or are forced to make it all work) use the new driver you just downloaded: certainly the best solution for those who want to use the latest version of the driver, but in this case require some adjustments to the software before proceeding with compilation ... (is the topic of another post ...).


Note riquardo software system configuration

final consideration with respect to software used by the my distribution. Using both KDE4 that LXDE on the same PC, I decided to install "Wicd Network Manager, uninstalling" network-manager "and" network-manager-gnome "(so you can use the same program on both interfaces.)

Then in the "System Settings" in KDE on the "Advanced" under "Hardware", I set as the default backend for network management, "the program" Wicd ".
