I've been trying to get my D-Link DWA-140(H/W working properly for quite some time. I've tried several guides including: D'Link Wireless DWA-140 speeds are crippled on 12.04 but I still have slow and unstable connection. What do I do?

I notice that compiling that file gave me rt5370sta but shouldn't it be RT3072?

Here is some more information: mattias@ubuntudator:~$ lsusb

It seems you have to blacklist all your rt mods except the rt5370sta one.

sudo gedit /etc/modprobe.d/blacklist.conf

Add those lines:

blacklist rt2800usb
blacklist rt2800lib
blacklist rt2x00usb
blacklist rt2x00lib

Then reboot.

Check this guide for a new installation: http://www.konopolis.com/iniciativas/instalacion-de-d-link-wifi-usb-dwa-140-en-ubuntu-12-04-lts.html It's in spanish, but commands are well explained. I've followed it and my DWA-140/B3 is working great.

Regards.
