I'm trying to install D-Link DWA-140 in a fresh install of Sabayon. Im following this guide How to make DLink DWA-140 B2 perfectly work on Linux and I've reached step 5 where I get this error msg:

Code:

sabayon mattias # wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf
Could not set interface wlan0 flags: No such file or directory
Failed to initialize driver interface

ndiswrapper says this:

Code:

sabayon mattias # ndiswrapper -l
drt2870 : driver installed
	device (07D1:3C0A) present (alternate driver: rt2800usb)

And my entire wpa_supplicant.conf consists of

Code:

network={
	ssid="Snaret"
	#psk="Correct pswd"
	psk=35487fb1c52502fa683cbd5abff5ee139ca17996e2584ee0c3869f6f3dc3cbea
}

Help!

Got help over at the Ubuntu IRC. It appears that if you hover the mouse over Network Manager it will say something like: "Device not active(firmware missing)". From here you will know that two drivers are loaded at once, causing none to be used. You do this by first determining what driver you should be using by "lsusb"(I think) and then "sudo lsmod | grep rt28" to see that two are loaded.

Now you need to follow the guide Ralink RT2870 based USB Wireless N adapters (Ubuntu) by Mark Greaves (PCNetSpec).

Got this to work on my Ubuntu 10.04 64-bit. I suppose not having firmware installed caused the problem. Also, you dont need to use ndiswrapper the drivers are loaded by default.
