국내에서 판매하는 n지원 무선랜은 대부분 요 칩셋인듯 한데…
우분투 10.10사용중입니다… 인식은 문제없는데, 채널이 1~11까지밖에 안잡힙니다… 전 13번 채널을 사용해야 하거든요…
rt2870드라이버 파일중에서 rt2870sta.bat파일 요놈이 설정파일이던데, 지역코드가 1~14번까지 가능한 지역으로 기본이 돼 있는 상태였고, 1~13번지역으로 변경후에 설치를 해도 채널이 11번까지밖에 안나오네요…
어떻게 해야 채널을 13번까지 잡게 하는지 성공하신 분들 좀 알려주세요~~
보통 rt2870에 관한 문제라면
rt2X00 오픈소스 드라이버와 rt2870sta의 독점 드라이버로 인한 문제가 많은데…
그건 아닌가보네요 ㅠㅠ
잘모르겠어요…
별개의 이야기지만, 제 노트북은 미국 판매 제품이어서 무선랜 채널을 하드웨어적으로 11채널까지 밖에 지원하지 않았던 기억이 나는군요~_~ 13채널에는 아예 접속할 수도 없었죠.
/etc/modprobe.d/blacklist.conf
위의 파일에 아래 내용을 첨부하여서 시도해보시기 바랍니다.
blacklist rt2800usb
아래 내용을 참조하시고요.
한단계씩 천천히 해보세요.
Re: RT2870. Help!
Wireless usb : Asus USB-N11
Chip : Ralink rt2870
Finally my wireless usb is detected by ubuntu karmic, and connect to internet.
Here are the procedures to get it done for those who have the rt2870 chipset.
To make your wireless dectectable.
Step 0 : At terminal, aaa@ubuntu:~$ sudo gedit /etc/modprobe.d/blacklist.conf
Add “blacklist rt2800usb” without quote at the end of the file, then save it.
Step 1 : Download the latest rt2870 driver ( 2009_0820_RT2870_Linux_STA_V2.2.0.0.tar.bz2 ) from Ralink.
Step 2 : Untar the file and save to your home folder, and name it (my folder is rt2870).
Step 3 : Don’t plug your wireless usb at this moment, at terminal aaa@ubuntu:~$ type lsusb.
Step 4 : Now plug in your wireless usb to the computer, type lsusb again, you will find your wireless usb ID (8 digits). Write it down.
Step 5 : Check your
At aaa@ubuntu:~/rt2870/os/linux$, sudo gedit usb_main_dev.c, check your usb device is included, if not, add your wireless usb ID. Save the file. It is quite interesting for my asus usb ID, I have to add two lines.
{USB_DEVICE(0x0B05,0x1761)}, /* Asus /
{USB_DEVICE(0x1761,0x0B05)}, / Asus */
Step 6 : At same terminal , sudo gedit config.mk, and change two settings.
HAS_WPA_SUPPLICANT=n → y
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n → y
Step 7 : At aaa@ubuntu:~/rt2870$, sudo gedit Makefile, check the folllowing at the top of the file:
RT28xx_MODE = STA
TARGET = LINUX
CHIPSET = 2870
If ok, close the file. If not, change the setting as above.
Step 8: rt2870 2.2.00 version do not support kernel 2.6.31-14-generic, so you have to do a patch.
Googling RT2870-2.6.31.patch, download it to rt2870 folder, then do the patch. If you get a message of unable to patch, then download and install Patch_2.5.9-5_amd64.deb. You will then able to patch RT2870-2.6.31.patch
At aaa@ubuntu:~/rt2870$ patch -p1 < rt2870-2.6.31.patch
Step 9 : At aaa@ubuntu:~/rt2870$, do the compilation.
sudo make uninstall
sudo make clean
sudo make
sudo make install
Step 10 : At aaa@ubuntu:~$ sudo modprobe rt2870sta
Step 11 : At aaa@ubuntu”~$ sudo gedit /etc/rc.local, add following two lines prior to exit0.
ifconfig ra0 up
pkill NetworkManager
save it, then at same terminal, sudo gedit /etc/modules, add rt2870sta, then save the file.
Step 12 :At aaa@ubuntu:~$ ifconfig or iwconfig, you will see your wireless is up as ra0 or wlan0.
Step 13 : Now configure networkmanager, use wep instead of wpa-psk or wpa2-psk. Your wireless will be able to connect to the internet. If there’s no connection, then do step 13.
Step 13 : Update networkmanager. Go to System – Software Sources – Other software, add the following line
deb http://ppa.launchpad.net/network-manager/trunk/ubuntu karmic main
It works.
