I have a Trim-Slice Value using Ubuntu 11.04. It comes with a Ralink RT5370 802.11n WiFi dongle.

When I plug the dongle in, it does not 'just work'; ifconfig and iwconfig do not show the device, though lsusb does show the device listed:

phrogz@trimslice:~$ lsusb | grep Ralink
Bus 001 Device 004: ID 148f:5370 Ralink Technology, Corp. 

I downloaded the link for RT5370 from Ralink's Linux Drivers site, resulting in a file named 2011_0225_RT5370_RT5372_Linux_STA_V2.5.0.1_DPO.tar.bz2. After extracting it, the only README in the file mentions the "RT2870 Wireless Lan Linux Driver"; however, the Makefile at the root of the directory does have these lines:

ifeq ($(CHIPSET),)
CHIPSET = 5370
endif

I edited os/linux/config.mk to have these settings:

# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y

# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

When I return to the root of the extracted directory and run make, however, it fails:

phrogz@trimslice:~/2011_0225_RT5370_RT5372_Linux_STA_V2.5.0.1_DPO$ sudo make
[sudo] password for phrogz:

make: *** /lib/modules/2.6.38.3-trimslice-1.03/build: No such file or directory.  Stop.
make: *** [LINUX] Error 2

How can I build the driver for this device?

I use a Tenda W311M that uses the same chip. Thanks for mentioning the download URL for the driver.

This thread http://ubuntuforums.org/showthread.php?t=1285828 mentions the solution.

I hope it works for you.

Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. –  Stefano Palazzo Feb 8 '12 at 8:58

You have to install Linux headers corresponding to you kernel release, to get the build directory mentioned:

apt-get install linux-headers-[version]

You can get the kernel release by typing:

uname -r
