lAN*4：1000M
wAN*1：1000M
WIFI：300M 天线可拆卸
JNR3210 CPU主频率达到了非常高的620Mhz,(一般无线路由CPU在400Mhz以下)
采用了 Realtek RTL8198(620Mhz) + RTL8192CE
详细测评在此http://www.360doc.com/content/12/0506/01/3220376_208948057.shtml
砖头是因为升级最新官方固件过程中断电所致，论坛没有该路由的相关资料，所以摸着石头过河！首先准备编程器，复制出原来坏的固件，提取出前128K CFE，然后烧写入闪存，焊接回路由，(因不知道怎么停止CFE启动，常规停止方法都是试过无效，故出此方法，单写CFE硬性停止，此处还望高手指点，后附正常CFE启动信息，可做参考，以备其他无编程器的同学思考)，再准备TFTP，设置好本地连接，设置好TTL比特率，如下图
本地连接设置
TTL比特率设置
路由TTL脚位定义
TFTP设置
把原厂页面升级固件后缀改为 .bin 然后浏览到要刷的固件待用
上述准备妥当后，连接好网线，通电，看到TTL显示如下图
启动至此见Enter TFTP_REC_wait4pkt时可以按TFTP更新固件按钮，TTL通信出现如下图
说明刷写正常，耐心等待，直到出现下图后提示闪存刷写固件成功，如图
然后断电重启，可见原厂固件界面，默认登录地址192.168.1.1登录账户为admin/password
至此救砖头成功!
