Ralink wireless driver in Ubuntu 10.04

In ubuntu 10.04, if it is a ralink wireless network adapter, it may be connected to a wireless network that is not encrypted or TKIP, but cannot be connected to a CCMP wireless network. This is because the system's built-in rt2870sta driver has a bug. The system comes with the 2870sta and 3070sta drivers, so there are conflicts during loading. Therefore, you need to add other unused blacklist drivers or simply delete them directly, however, the original 3070sta of my system was not working properly. If I deleted it in my anger, I had to edit it myself. 9.10 of the time was a long time, but I cannot remember it for a long time. This time, I will try again to avoid further trouble. I would like to write a short article.

 

 

1. Add rt2870sta to the blacklist, that is, blacklist rt2870sta.

Gedit/etc/modprobe. d/blacklist. conf

Add the following lines at the end of the file:

Blacklist rt2800usb

Blacklist rt2x00lib

Blacklist rt2x00usb

Blacklist rt2870sta

 

 

2. Download ralink for 2.6 kernel chipset 3070 prepare driver http://www.ralinktech.com/support.php? S = 2

(Rt3070_linuxsta_v2.3.0.20.20100208.tar.gz 2)

 

Decompress the package. Compile.

Failed to manually load the kernel. error message:

 

Insmod: Error inserting './rt3070sta. Ko':-1 unknown symbol in Module

Run the command # dmesg | grep-e rT3 to obtain the information.

Note that the first line indicates that the license of the module threatens the kernel. Obviously, this is a license problem. Solution: # grep module_lic *./-r -- include = *. c ./Common/rtmp_init.c: module_license ("ralink "); ./OS/Linux/rt_linux.c: module_license ("GPL "); ./OS/Linux/rt_main_dev.c: module_license ("GPL ")
Edit rt_linux.c and rt_main_dev.c, and remove the ifdef that limits module_license ("GPL") to recompile.

 

 

3. There is a small problem during sudo make install and an error is prompted.

 

CP: cannot stat '~ /Ralink/rt3070_linuxsta_v2.3.0.20.20100208/rt3070sta. dat ': no such file or directory

Solution: CP rt2879sta. dat rt3070sta. dat, and then sudo make install

Basically, I also rely on gooooogle to do these things. It's really a good thing. I have to turn it around when I learn technology! 4. Reference: http://ubuntuforums.org/showthread.php? T = 1407165
