I just wanted to share how I got the rt2870 Wifi 802.11abgn chipset to work with Intrepid Ibex.

I ordered two [b]ENGENIUS EUB-9701 EXT - EUB9701X2[/b] because it had two external antennas and also of course the rt2870 chipset.

The driver from Ralink needs a patch to work with kernels newer than 2.6.24. The patch was made by a user on these forums and posted on Launchpad. Thank god for that. I was getting mad with ndiswrapper.

Install build-essential (This may not be needed so try the next steps without build-essential first).

 

sudo apt-get install build-essential

 

Create a directory in for example your home directory to keep all the files.

 

cd ~/

mkdir rt2870

cd rt2870

 

Now retrieve the driver

 

http://www.ralinktech.com.tw/data/drivers/2008_0925_RT2870_Linux_STA_v1.4.0.0.tar.bz2

 

Extract the compressed driver directory and files.

 

tar xvfj 2008_0925_RT2870_Linux_STA_v1.4.0.0.tar.bz2

 

Enter the directery and edit the config.mk file so that the driver will support NetworkManager

 

Change from this

 

# Support Wpa_Supplicant

HAS_WPA_SUPPLICANT=n

 

 

# Support Native WpaSupplicant for Network Magang

HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n

 

to this

 

# Support Wpa_Supplicant

HAS_WPA_SUPPLICANT=y

 

 

# Support Native WpaSupplicant for Network Maganger

HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

 

Compile and install.

 

 

cd

2008_0925_RT2870_Linux_STA_v1.4.0.0.tar.bz2

sudo make

sudo make install

 

Edit the Ralink settings file to your liking.

 

 

sudo nano /etc/Wireless/RT2870STA/RT2870STA.dat

 

 

 

This is what mine looks like without the passwords and accesspoint.

I think the important part of my changes is this.

 

 

AuthMode=WPA

 

 

 

This was what I had to change to make the driver work with NetworkManager.

 

Now make the driver load at bootup

 

 

sudo nano /etc/modules

 

and add this line to the the file.

 

 

alias ra0 rt2870sta

 

 

 

My /etc/modules looks like this.

 

 

# /etc/modules: kernel modules to load at boot time.

#

# This file contains the names of kernel modules that should be loaded

# at boot time, one per line. Lines beginning with "#" are ignored.

fuse

lp

sbp2

#ndiswrapper

uinput

alias ra0 rt2870sta

# Added for Nero Linux device access

sg

 

Add an ugly fix to make the ra0 interface come up during each boot. There must be a better way which I hope someone here knows of.

 

 

sudo nano /etc/init.d/rc.local

 

 

 

and add these lines to the end of the file

 

ifconfig ra0 inet up

/etc/init.d/NetworkManager restart

 

Reboot and it should work. It did for me.
