故障内容如下:

2.4Ghz 获取IP过慢，且5Ghz无法正常驱动
启动过程中黄灯未常亮，而是蓝灯闪烁启动
固件网页设置中，无法正常识别到5Ghz无线网卡，且一网卡驱动不上，修改时显示为2.4Ghz无线网卡，怀疑是驱动混乱

考虑到可能是乌班图系统问题故更换系统为乌班图20.10

安装环境

拉取源码

git clone https://github.com/coolsnowwolf/lede
cd lede
./scripts/feeds clean
./scripts/feeds update -a
./scripts/feeds install -a

安装宝塔

wget -O install.sh http://download.bt.cn/install/install-ubuntu_6.0.sh && sudo bash install.sh

开防火墙

sudo ufw allow 8888
#允许外部访问8888端口(tcp/udp)

上传历史文件

开始编译

cd /lede
make menuconfig

遇到报错 Build dependency: Please install GNU 'awk' Prerequisite check failed. Use FORCE=1 to override. make: *** [/home/yuos/lede/include/toplevel.mk:174：staging_dir/host/.prereq-build] 错误 1

sudo apt-get install subversion gawk
#问题解决
make menuconfig
/*选择配置*/
make -j8 download V=s
#下载dl库（国内请尽量全局科学上网）

编译成功

建议搭配魔改版信号文件食用效果更佳

Thanks.
I got Mir3 openwrt firmware. it worked very well.
I try build firmware for Mi4A gigabit and R3G, signal is not good.
Mi R4A gigabit 's 5Ghz singal only have 1dBm Transmit power
R3G only have 5Ghz and 1dBm power.
Those is source code i had try:

    No, i dont.
    can you show me how to do it?
    i cpoied folder: https://github.com/MeIsReallyBa/Redmi2100-WIFI-ProprietaryDriver-linux5.4
    to lede/package/lean/mt
    but 5Ghz band still weak

    I am amatuer.
    So i dont know how to change driver open source to close source!
    Can you explain step by step?
    "请问ac2100需要将哪几个设置替换成闭源驱动，谢谢~"

老大在吗今天我把TP 740NV5 9331的装上了X-OPENWRT
进去后发现没shadonsockts plus+ 郁闷了
这个怎么把SHADONSOCKTS PLUS+ 加进去
https://downloads.x-wrt.com/rom/
下载的740N V1的这个文件x-wrt-9.0-b202104170928-ath79-generic-tplink_tl-wr710n-v1-squashfs-sysupgrade.bin

  不客气，我的主要问题是为了自己成砖的小米路由3编译的，话说好好的小米路由3你为啥要硬改呢，难道只是为了刷不死吗(๑•̀ㅁ•́ฅ)

故障内容如下:

2.4Ghz 获取IP过慢，且5Ghz无法正常驱动
启动过程中黄灯未常亮，而是蓝灯闪烁启动
固件网页设置中，无法正常识别到5Ghz无线网卡，且一网卡驱动不上，修改时显示为2.4Ghz无线网卡，怀疑是驱动混乱
