TPLINK-841N_V3.4刷OPENWRT

昨天晚上把手里的841n V3.4改成openwrt了,要用单wan双拨功能

在网上走了几圈。发现有改这个机子成功的了。

于是,开始动手,上TTL无信息,R356直连后还是不行(rx,tx,gnd)

无果,没TTL如何刷呢,分析网上的方法后。闪光一灵,直接用编程器刷,分析后得出结论

0x0000-0x20000存放uboot

0x20001-0x7f0000存放factory命令的固件

0x7f0001-0x800000存放的是board_config

按顺序刷上后,一切OK成功了

编程器固件下载:

昨天安装了 debian 发现只能使用有线网卡上网,无线无法使用,用lsmod看也挂载了RT73的模式,但是dmesg后发现

用桌面工具也搜不到无线网,手工加入也是上不了
ifup wlan0显示
Ignoring unknown interface wlan0=wlan0

iwlist wlan0 scanning
显示网卡没有启动

这里有点晕菜了,后来发现应该是驱动的问题

下边说说解决的过程
我下载的的debian5.08 i386 DVD 第一张盘
安装后并无iwlist之类的命令,要自己安
aptitude install frimware-iwlwifi wireless-tools
安完后
再安装雷凌网卡的驱动包就OK了
aptitude install firmware-ralink
然后就看到nm-applet搜出了无线信号
问题解决了
