How to install a D-Link DWA-525 wireless network card in Ubuntu 10.04（不一定哟，我的就是10.10）

I was having an issue with an old network card in my Ubuntu machine (x86 arch), so I went out and got a new one that supports 802.11n. It’s been some time since I swapped out hardware, and Linux has matured greatly since then: the last install of Ubuntu detected everything perfectly, first time, including the network devices!

Not so for this network card. After much searching it turns out it’s actually unsupported [1] out of the box. Bah! I finally found the information I need to get it running. This article is a combination of several articles [2], [3], [4], I had to borrow bits and pieces from all of them, listed below.

Here’s how to get up and running with the D-Link DWA-525 on Ubuntu 10.04:

1. Install the card and power up the machine.

2. Open the terminal and run

lspci


In the list you will see:

Network Controller: Ralink Device 3060 0


So now we know what device we need drivers for.

3. Go to http://www.ralinktech.com/support.php?s=2 and download theRT3062PCI/mPCI/CB/PCIe(RT3060/RT3062/RT3562/RT3592) drivers.

You’ll be prompted for your name and email but you don’t need to sign into anything.

4. Extract the package and cd to the directory.

5. We need to make a slight modification to the configuration for the driver:

nano os/linux/config.mk


And set:

# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y

# Support Native WpaSupplicant for Network Manager
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y


By default they are both set to ‘n’. Save and close the file.

6. From the top level directory, compile and install the driver:

sudo su
make && make install

You need to use ‘sudo su’ and not just ‘sudo’ so it creates the directories properly.

7. After compilation, and whist still root, modprobe the driver:

modprobe rt3562sta


You should get no output signalling success.

8. Now an important step. We need to blacklist a conflicting driver that will be loaded preferentially for this network card.

sudo nano /etc/modprobe.d/blacklist.conf


and enter the following line at the bottom of the file:

blacklist rt2800pci


Save and close.

9. Restart the machine.

10. When the machine is back up, verify the driver has been loaded and is being used by the device:

lsmod


You should see the following in the list:

rt3562sta     924607     1


11. Now, launch the Network Manager and it should have detected the available wireless networks and you can configure the one you want.

经验分享：

1，先切换到超级用户态，即sudo su，不然后面的make和make install有无法正确安装。

2，驱动程序最好别用光盘自带的那个，到ralink官网去下载最新的，网址在上面有给出。

3，安装ubuntu系统时最好别用wubi安装（为啥？我也不知道现在，求解 ~），我就是用这个安装后，最后怎么弄都不行，具体当时的状况就是当我把rt3562的驱动装好后，用iwlist scanning发现可以搜索到网络，但在network-manager上却死活搜不出来，一顿无语，无奈换回grub安装，这个安装方法在网上一搜一大把，另外个人觉得wubi这玩意安装后，等到哪天在windows上一误操作（啪，格式化了），那就泪流满面了。。其它的就基本上按照这篇文章这样做就是了。。

PS：

个人尝试过wicd，当时是想代替network-manager去做网络搜索功能，貌似确实可以搜索到无线网络，不过在连接的过程中出错了，原因可能是wicd依赖的其它文件安装不对，所以wicd安装起来还是比较麻烦的，所以觉得吧network-manager就够用了。

呵呵，当然连无线，几个常用命令还得知道啊：iwconfig/iwlist scanning/lspci -k
