wifi很慢,卡RT5390

我有全新的 ASUS X501A 和 Ubuntu 12.04(我不擅长使用 Ubuntu),WiFi 非常慢 - 1Mb/s。WiFi 芯片是 RT5390。

我尝试了在网上找到的所有方法,因此我需要一步一步的指导。

答案1

我也有一台华硕 X501A,我也遇到了同样的问题,无线速度很慢。

我按照这篇文章中的说明进行操作: 无法在 13.04 下使用 wifi(Ralink rt5390)

基本上,您要执行以下操作(取自上面的帖子):

  1. 输入您的姓名和电子邮件并下载驱动程序:http://www.mediatek.com/_en/07_downl...il.php?sn=5001
  2. 转到下载目录并运行以下命令

    tar -xvf 2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO_v2.bz2.bz2
    cd 2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO
    wget http://gridlox.net/diff/rt5592sta_fix_64bit_3.8.patch
    patch -p1 <rt5592sta_fix_64bit_3.8.patch
    

    如果补丁要求目录,请将其指向 pci_main_dev.c

  3. 确保 ./os/linux/config.mk 读取 HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

  4. 构建并安装驱动程序:

    make
    sudo make install
    sudo modprobe rt5390sta
    

    我在命令末尾收到各种编译器警告和错误消息,make提示我没有足够的权限,但在之后它就可以正常工作了sudo make install

  5. 将冲突的内核模块列入黑名单,然后运行

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

    然后在文件末尾添加以下行:

    # Blacklist conflicting kernel modules
    blacklist rt2800pci
    blacklist rt2800lib
    blacklist rt2x00usb
    blacklist rt2x00pci
    blacklist rt2x00lib
    blacklist rt2860sta
    blacklist rt3090st
    
  6. 重启后,无线速度应该会更快。我不得不重新输入无线密码,但效果很好。
